GNU GENERAL PUBLIC LICENSE
|
||||
Version 2, June 1991
|
||||
|
||||
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
|
||||
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
License is intended to guarantee your freedom to share and change free
|
||||
software--to make sure the software is free for all its users. This
|
||||
General Public License applies to most of the Free Software
|
||||
Foundation's software and to any other program whose authors commit to
|
||||
using it. (Some other Free Software Foundation software is covered by
|
||||
the GNU Library General Public License instead.) You can apply it to
|
||||
your programs, too.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. Our General Public Licenses are designed to make sure that you
|
||||
have the freedom to distribute copies of free software (and charge for
|
||||
this service if you wish), that you receive source code or can get it
|
||||
if you want it, that you can change the software or use pieces of it
|
||||
in new free programs; and that you know you can do these things.
|
||||
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
anyone to deny you these rights or to ask you to surrender the rights.
|
||||
These restrictions translate to certain responsibilities for you if you
|
||||
distribute copies of the software, or if you modify it.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must give the recipients all the rights that
|
||||
you have. You must make sure that they, too, receive or can get the
|
||||
source code. And you must show them these terms so they know their
|
||||
rights.
|
||||
|
||||
We protect your rights with two steps: (1) copyright the software, and
|
||||
(2) offer you this license which gives you legal permission to copy,
|
||||
distribute and/or modify the software.
|
||||
|
||||
Also, for each author's protection and ours, we want to make certain
|
||||
that everyone understands that there is no warranty for this free
|
||||
software. If the software is modified by someone else and passed on, we
|
||||
want its recipients to know that what they have is not the original, so
|
||||
that any problems introduced by others will not reflect on the original
|
||||
authors' reputations.
|
||||
|
||||
Finally, any free program is threatened constantly by software
|
||||
patents. We wish to avoid the danger that redistributors of a free
|
||||
program will individually obtain patent licenses, in effect making the
|
||||
program proprietary. To prevent this, we have made it clear that any
|
||||
patent must be licensed for everyone's free use or not licensed at all.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
GNU GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License applies to any program or other work which contains
|
||||
a notice placed by the copyright holder saying it may be distributed
|
||||
under the terms of this General Public License. The "Program", below,
|
||||
refers to any such program or work, and a "work based on the Program"
|
||||
means either the Program or any derivative work under copyright law:
|
||||
that is to say, a work containing the Program or a portion of it,
|
||||
either verbatim or with modifications and/or translated into another
|
||||
language. (Hereinafter, translation is included without limitation in
|
||||
the term "modification".) Each licensee is addressed as "you".
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running the Program is not restricted, and the output from the Program
|
||||
is covered only if its contents constitute a work based on the
|
||||
Program (independent of having been made by running the Program).
|
||||
Whether that is true depends on what the Program does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Program's
|
||||
source code as you receive it, in any medium, provided that you
|
||||
conspicuously and appropriately publish on each copy an appropriate
|
||||
copyright notice and disclaimer of warranty; keep intact all the
|
||||
notices that refer to this License and to the absence of any warranty;
|
||||
and give any other recipients of the Program a copy of this License
|
||||
along with the Program.
|
||||
|
||||
You may charge a fee for the physical act of transferring a copy, and
|
||||
you may at your option offer warranty protection in exchange for a fee.
|
||||
|
||||
2. You may modify your copy or copies of the Program or any portion
|
||||
of it, thus forming a work based on the Program, and copy and
|
||||
distribute such modifications or work under the terms of Section 1
|
||||
above, provided that you also meet all of these conditions:
|
||||
|
||||
a) You must cause the modified files to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
b) You must cause any work that you distribute or publish, that in
|
||||
whole or in part contains or is derived from the Program or any
|
||||
part thereof, to be licensed as a whole at no charge to all third
|
||||
parties under the terms of this License.
|
||||
|
||||
c) If the modified program normally reads commands interactively
|
||||
when run, you must cause it, when started running for such
|
||||
interactive use in the most ordinary way, to print or display an
|
||||
announcement including an appropriate copyright notice and a
|
||||
notice that there is no warranty (or else, saying that you provide
|
||||
a warranty) and that users may redistribute the program under
|
||||
these conditions, and telling the user how to view a copy of this
|
||||
License. (Exception: if the Program itself is interactive but
|
||||
does not normally print such an announcement, your work based on
|
||||
the Program is not required to print an announcement.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Program,
|
||||
and can be reasonably considered independent and separate works in
|
||||
themselves, then this License, and its terms, do not apply to those
|
||||
sections when you distribute them as separate works. But when you
|
||||
distribute the same sections as part of a whole which is a work based
|
||||
on the Program, the distribution of the whole must be on the terms of
|
||||
this License, whose permissions for other licensees extend to the
|
||||
entire whole, and thus to each and every part regardless of who wrote it.
|
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest
|
||||
your rights to work written entirely by you; rather, the intent is to
|
||||
exercise the right to control the distribution of derivative or
|
||||
collective works based on the Program.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Program
|
||||
with the Program (or with a work based on the Program) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may copy and distribute the Program (or a work based on it,
|
||||
under Section 2) in object code or executable form under the terms of
|
||||
Sections 1 and 2 above provided that you also do one of the following:
|
||||
|
||||
a) Accompany it with the complete corresponding machine-readable
|
||||
source code, which must be distributed under the terms of Sections
|
||||
1 and 2 above on a medium customarily used for software interchange; or,
|
||||
|
||||
b) Accompany it with a written offer, valid for at least three
|
||||
years, to give any third party, for a charge no more than your
|
||||
cost of physically performing source distribution, a complete
|
||||
machine-readable copy of the corresponding source code, to be
|
||||
distributed under the terms of Sections 1 and 2 above on a medium
|
||||
customarily used for software interchange; or,
|
||||
|
||||
c) Accompany it with the information you received as to the offer
|
||||
to distribute corresponding source code. (This alternative is
|
||||
allowed only for noncommercial distribution and only if you
|
||||
received the program in object code or executable form with such
|
||||
an offer, in accord with Subsection b above.)
|
||||
|
||||
The source code for a work means the preferred form of the work for
|
||||
making modifications to it. For an executable work, complete source
|
||||
code means all the source code for all modules it contains, plus any
|
||||
associated interface definition files, plus the scripts used to
|
||||
control compilation and installation of the executable. However, as a
|
||||
special exception, the source code distributed need not include
|
||||
anything that is normally distributed (in either source or binary
|
||||
form) with the major components (compiler, kernel, and so on) of the
|
||||
operating system on which the executable runs, unless that component
|
||||
itself accompanies the executable.
|
||||
|
||||
If distribution of executable or object code is made by offering
|
||||
access to copy from a designated place, then offering equivalent
|
||||
access to copy the source code from the same place counts as
|
||||
distribution of the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
4. You may not copy, modify, sublicense, or distribute the Program
|
||||
except as expressly provided under this License. Any attempt
|
||||
otherwise to copy, modify, sublicense or distribute the Program is
|
||||
void, and will automatically terminate your rights under this License.
|
||||
However, parties who have received copies, or rights, from you under
|
||||
this License will not have their licenses terminated so long as such
|
||||
parties remain in full compliance.
|
||||
|
||||
5. You are not required to accept this License, since you have not
|
||||
signed it. However, nothing else grants you permission to modify or
|
||||
distribute the Program or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Program (or any work based on the
|
||||
Program), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Program or works based on it.
|
||||
|
||||
6. Each time you redistribute the Program (or any work based on the
|
||||
Program), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute or modify the Program subject to
|
||||
these terms and conditions. You may not impose any further
|
||||
restrictions on the recipients' exercise of the rights granted herein.
|
||||
You are not responsible for enforcing compliance by third parties to
|
||||
this License.
|
||||
|
||||
7. If, as a consequence of a court judgment or allegation of patent
|
||||
infringement or for any other reason (not limited to patent issues),
|
||||
conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot
|
||||
distribute so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you
|
||||
may not distribute the Program at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Program by
|
||||
all those who receive copies directly or indirectly through you, then
|
||||
the only way you could satisfy both it and this License would be to
|
||||
refrain entirely from distribution of the Program.
|
||||
|
||||
If any portion of this section is held invalid or unenforceable under
|
||||
any particular circumstance, the balance of the section is intended to
|
||||
apply and the section as a whole is intended to apply in other
|
||||
circumstances.
|
||||
|
||||
It is not the purpose of this section to induce you to infringe any
|
||||
patents or other property right claims or to contest validity of any
|
||||
such claims; this section has the sole purpose of protecting the
|
||||
integrity of the free software distribution system, which is
|
||||
implemented by public license practices. Many people have made
|
||||
generous contributions to the wide range of software distributed
|
||||
through that system in reliance on consistent application of that
|
||||
system; it is up to the author/donor to decide if he or she is willing
|
||||
to distribute software through any other system and a licensee cannot
|
||||
impose that choice.
|
||||
|
||||
This section is intended to make thoroughly clear what is believed to
|
||||
be a consequence of the rest of this License.
|
||||
|
||||
8. If the distribution and/or use of the Program is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Program under this License
|
||||
may add an explicit geographical distribution limitation excluding
|
||||
those countries, so that distribution is permitted only in or among
|
||||
countries not thus excluded. In such case, this License incorporates
|
||||
the limitation as if written in the body of this License.
|
||||
|
||||
9. The Free Software Foundation may publish revised and/or new versions
|
||||
of the General Public License from time to time. Such new versions will
|
||||
be similar in spirit to the present version, but may differ in detail to
|
||||
address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the Program
|
||||
specifies a version number of this License which applies to it and "any
|
||||
later version", you have the option of following the terms and conditions
|
||||
either of that version or of any later version published by the Free
|
||||
Software Foundation. If the Program does not specify a version number of
|
||||
this License, you may choose any version ever published by the Free Software
|
||||
Foundation.
|
||||
|
||||
10. If you wish to incorporate parts of the Program into other free
|
||||
programs whose distribution conditions are different, write to the author
|
||||
to ask for permission. For software which is copyrighted by the Free
|
||||
Software Foundation, write to the Free Software Foundation; we sometimes
|
||||
make exceptions for this. Our decision will be guided by the two goals
|
||||
of preserving the free status of all derivatives of our free software and
|
||||
of promoting the sharing and reuse of software generally.
|
||||
|
||||
NO WARRANTY
|
||||
|
||||
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
|
||||
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
|
||||
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
|
||||
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
|
||||
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
||||
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
|
||||
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
|
||||
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
|
||||
REPAIR OR CORRECTION.
|
||||
|
||||
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
|
||||
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
|
||||
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
|
||||
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
|
||||
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
|
||||
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
|
||||
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
|
||||
POSSIBILITY OF SUCH DAMAGES.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
How to Apply These Terms to Your New Programs
|
||||
|
||||
If you develop a new program, and you want it to be of the greatest
|
||||
possible use to the public, the best way to achieve this is to make it
|
||||
free software which everyone can redistribute and change under these terms.
|
||||
|
||||
To do so, attach the following notices to the program. It is safest
|
||||
to attach them to the start of each source file to most effectively
|
||||
convey the exclusion of warranty; and each file should have at least
|
||||
the "copyright" line and a pointer to where the full notice is found.
|
||||
|
||||
<one line to give the program's name and a brief idea of what it does.>
|
||||
Copyright (C) <year> <name of author>
|
||||
|
||||
This program is free software; you can redistribute it and/or modify
|
||||
it under the terms of the GNU General Public License** as published by
|
||||
the Free Software Foundation; either version 2 of the License, or
|
||||
(at your option) any later version.
|
||||
|
||||
This program is distributed in the hope that it will be useful,
|
||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
||||
GNU General Public License for more details.
|
||||
|
||||
You should have received a copy of the GNU General Public License
|
||||
along with this program; if not, write to the Free Software
|
||||
Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
|
||||
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
If the program is interactive, make it output a short notice like this
|
||||
when it starts in an interactive mode:
|
||||
|
||||
Gnomovision version 69, Copyright (C) year name of author
|
||||
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
|
||||
This is free software, and you are welcome to redistribute it
|
||||
under certain conditions; type `show c' for details.
|
||||
|
||||
The hypothetical commands `show w' and `show c' should show the appropriate
|
||||
parts of the General Public License. Of course, the commands you use may
|
||||
be called something other than `show w' and `show c'; they could even be
|
||||
mouse-clicks or menu items--whatever suits your program.
|
||||
|
||||
You should also get your employer (if you work as a programmer) or your
|
||||
school, if any, to sign a "copyright disclaimer" for the program, if
|
||||
necessary. Here is a sample; alter the names:
|
||||
|
||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
|
||||
`Gnomovision' (which makes passes at compilers) written by James Hacker.

||||
|
||||
This General Public License does not permit incorporating your program into
|
||||
proprietary programs. If your program is a subroutine library, you may
|
||||
consider it more useful to permit linking proprietary applications with the
|
||||
library. If this is what you want to do, use the GNU Library General
|
||||
Public License instead of this License.

The FreeRTOS GPL Exception Text:
|
||||
|
||||
Any FreeRTOS source code, whether modified or in it's original release form,
|
||||
or whether in whole or in part, can only be distributed by you under the terms
|
||||
of the GNU General Public License plus this exception. An independent module is
|
||||
a module which is not derived from or based on FreeRTOS.
|
||||
|
||||
Clause 1:
|
||||
|
||||
Linking FreeRTOS statically or dynamically with other modules is making a
|
||||
combined work based on FreeRTOS. Thus, the terms and conditions of the GNU
|
||||
General Public License cover the whole combination.
|
||||
|
||||
As a special exception, the copyright holder of FreeRTOS gives you permission
|
||||
to link FreeRTOS with independent modules that communicate with FreeRTOS
|
||||
solely through the FreeRTOS API interface, regardless of the license terms of
|
||||
these independent modules, and to copy and distribute the resulting combined
|
||||
work under terms of your choice, provided that
|
||||
|
||||
+ Every copy of the combined work is accompanied by a written statement that
|
||||
details to the recipient the version of FreeRTOS used and an offer by yourself
|
||||
to provide the FreeRTOS source code (including any modifications you may have
|
||||
made) should the recipient request it.
|
||||
|
||||
+ The combined work is not itself an RTOS, scheduler, kernel or related product.
|
||||
|
||||
+ The independent modules add significant and primary functionality to FreeRTOS
|
||||
and do not merely extend the existing functionality already present in FreeRTOS.
|
||||
|
||||
Clause 2:
|
||||
|
||||
FreeRTOS may not be used for any competitive or comparative purpose, including the
|
||||
publication of any form of run time or compile time metric, without the express
|
||||
permission of Real Time Engineers Ltd. (this is the norm within the industry and
|
||||
is intended to ensure information accuracy).

/**
|
||||
* An event group is a collection of bits to which an application can assign a
|
||||
* meaning. For example, an application may create an event group to convey
|
||||
* the status of various CAN bus related events in which bit 0 might mean "A CAN
|
||||
* message has been received and is ready for processing", bit 1 might mean "The
|
||||
* application has queued a message that is ready for sending onto the CAN
|
||||
* network", and bit 2 might mean "It is time to send a SYNC message onto the
|
||||
* CAN network" etc. A task can then test the bit values to see which events
|
||||
* are active, and optionally enter the Blocked state to wait for a specified
|
||||
* bit or a group of specified bits to be active. To continue the CAN bus
|
||||
* example, a CAN controlling task can enter the Blocked state (and therefore
|
||||
* not consume any processing time) until either bit 0, bit 1 or bit 2 are
|
||||
* active, at which time the bit that was actually active would inform the task
|
||||
* which action it had to take (process a received message, send a message, or
|
||||
* send a SYNC).
|
||||
*
|
||||
* The event groups implementation contains intelligence to avoid race
|
||||
* conditions that would otherwise occur were an application to use a simple
|
||||
* variable for the same purpose. This is particularly important with respect
|
||||
* to when a bit within an event group is to be cleared, and when bits have to
|
||||
* be set and then tested atomically - as is the case where event groups are
|

*
|
||||
* A version of xEventGroupClearBits() that can be called from an interrupt.
|
||||
*
|
||||
* Setting bits in an event group is not a deterministic operation because there
|
||||
* are an unknown number of tasks that may be waiting for the bit or bits being
|
||||
* set. FreeRTOS does not allow nondeterministic operations to be performed
|
||||
* while interrupts are disabled, so protects event groups that are accessed
|
||||
* from tasks by suspending the scheduler rather than disabling interrupts. As
|
||||
* a result event groups cannot be accessed directly from an interrupt service
|
||||
* routine. Therefore xEventGroupClearBitsFromISR() sends a message to the
|
||||
* timer task to have the clear operation performed in the context of the timer
|
||||
* task.
|
||||
*
|
||||
* @param xEventGroup The event group in which the bits are to be cleared.
|
||||
*
|
||||
* @param uxBitsToClear A bitwise value that indicates the bit or bits to clear.
|
||||
* For example, to clear bit 3 only, set uxBitsToClear to 0x08. To clear bit 3
|
||||
* and bit 0 set uxBitsToClear to 0x09.
|
||||
*
|
||||
* @return If the request to execute the function was posted successfully then
|
||||
* pdPASS is returned, otherwise pdFALSE is returned. pdFALSE will be returned
|
||||
* if the timer service queue was full.

|
||||
* ***NOTE***: Uniquely among FreeRTOS objects, the stream buffer
|
||||
* implementation (so also the message buffer implementation, as message buffers
|
||||
* are built on top of stream buffers) assumes there is only one task or
|
||||
* interrupt that will write to the buffer (the writer), and only one task or
|
||||
* interrupt that will read from the buffer (the reader). It is safe for the
|
||||
* writer and reader to be different tasks or interrupts, but, unlike other
|
||||
* FreeRTOS objects, it is not safe to have multiple different writers or
|
||||
* multiple different readers. If there are to be multiple different writers
|
||||
* then the application writer must place each call to a writing API function
|
||||
* (such as xMessageBufferSend()) inside a critical section and set the send
|
||||
* block time to 0. Likewise, if there are to be multiple different readers
|
||||
* then the application writer must place each call to a reading API function
|
||||
* (such as xMessageBufferRead()) inside a critical section and set the receive
|
||||
* timeout to 0.
|
||||
*
|
||||
* Message buffers hold variable length messages. To enable that, when a
|
||||
* message is written to the message buffer an additional sizeof( size_t ) bytes
|
||||
* are also written to store the message's length (that happens internally, with
|
||||
* the API function). sizeof( size_t ) is typically 4 bytes on a 32-bit
|
||||
* architecture, so writing a 10 byte message to a message buffer on a 32-bit
|
||||
* architecture will actually reduce the available space in the message buffer
|
||||
* by 14 bytes (10 byte are used by the message, and 4 bytes to hold the length
|
||||
* of the message).

* An interrupt safe version of the API function that receives a discrete
|

* message from a message buffer. Messages can be of variable length and are
|
||||
* copied out of the buffer.
|
||||
*
|
||||
* ***NOTE***: Uniquely among FreeRTOS objects, the stream buffer
|
||||
* implementation (so also the message buffer implementation, as message buffers
|
||||
* are built on top of stream buffers) assumes there is only one task or
|
||||
* interrupt that will write to the buffer (the writer), and only one task or
|
||||
* interrupt that will read from the buffer (the reader). It is safe for the
|
||||
* writer and reader to be different tasks or interrupts, but, unlike other
|
||||
* FreeRTOS objects, it is not safe to have multiple different writers or
|
||||
* multiple different readers. If there are to be multiple different writers
|
||||
* then the application writer must place each call to a writing API function
|
||||
* (such as xMessageBufferSend()) inside a critical section and set the send
|
||||
* block time to 0. Likewise, if there are to be multiple different readers
|
||||
* then the application writer must place each call to a reading API function
|
||||
* (such as xMessageBufferRead()) inside a critical section and set the receive
|
||||
* block time to 0.
|
||||
*
|
||||
* Use xMessageBufferReceive() to read from a message buffer from a task. Use
|
||||
* xMessageBufferReceiveFromISR() to read from a message buffer from an
|
||||
* interrupt service routine (ISR).
|
||||
*
|
||||
* @param xMessageBuffer The handle of the message buffer from which a message
|
||||
* is being received.
|
||||
*
|
||||
* @param pvRxData A pointer to the buffer into which the received message is
|
||||
* to be copied.
|
||||
*
|
||||
* @param xBufferLengthBytes The length of the buffer pointed to by the pvRxData
|
||||
* parameter. This sets the maximum length of the message that can be received.
|
||||
* If xBufferLengthBytes is too small to hold the next message then the message
|
||||
* will be left in the message buffer and 0 will be returned.
|
||||
*
|
||||
* @param pxHigherPriorityTaskWoken It is possible that a message buffer will
|
||||
* have a task blocked on it waiting for space to become available. Calling
|
||||
* xMessageBufferReceiveFromISR() can make space available, and so cause a task
|
||||
* that is waiting for space to leave the Blocked state. If calling
|
||||
* xMessageBufferReceiveFromISR() causes a task to leave the Blocked state, and
|
||||
* the unblocked task has a priority higher than the currently executing task
|
||||
* (the task that was interrupted), then, internally,
|
||||
* xMessageBufferReceiveFromISR() will set *pxHigherPriorityTaskWoken to pdTRUE.
|
||||
* If xMessageBufferReceiveFromISR() sets this value to pdTRUE, then normally a
|
||||
* context switch should be performed before the interrupt is exited. That will
|
||||
* ensure the interrupt returns directly to the highest priority Ready state
|
||||
* task. *pxHigherPriorityTaskWoken should be set to pdFALSE before it is
|
||||
* passed into the function. See the code example below for an example.
|
||||
*
|
||||
* @return The length, in bytes, of the message read from the message buffer, if
|
||||
* any.

* <pre>SemaphoreHandle_t xSemaphoreCreateBinary( void )</pre>
|
||||
*
|
||||
* Creates a new binary semaphore instance, and returns a handle by which the
|
||||
* new semaphore can be referenced.
|
||||
*
|
||||
* In many usage scenarios it is faster and more memory efficient to use a
|
||||
* direct to task notification in place of a binary semaphore!
|
||||
* http://www.freertos.org/RTOS-task-notifications.html
|
||||
*
|
||||
* Internally, within the FreeRTOS implementation, binary semaphores use a block
|
||||
* of memory, in which the semaphore structure is stored. If a binary semaphore
|
||||
* is created using xSemaphoreCreateBinary() then the required memory is
|
||||
* automatically dynamically allocated inside the xSemaphoreCreateBinary()
|
||||
* function. (see http://www.freertos.org/a00111.html). If a binary semaphore
|
||||
* is created using xSemaphoreCreateBinaryStatic() then the application writer
|
||||
* must provide the memory. xSemaphoreCreateBinaryStatic() therefore allows a
|
||||
* binary semaphore to be created without using any dynamic memory allocation.
|
||||
*
|
||||
* The old vSemaphoreCreateBinary() macro is now deprecated in favour of this
|
||||
* xSemaphoreCreateBinary() function. Note that binary semaphores created using
|
||||
* the vSemaphoreCreateBinary() macro are created in a state such that the
|
||||
* first call to 'take' the semaphore would pass, whereas binary semaphores
|
||||
* created using xSemaphoreCreateBinary() are created in a state such that the
|
||||
* the semaphore must first be 'given' before it can be 'taken'.
|
||||
*
|
||||
* This type of semaphore can be used for pure synchronisation between tasks or
|
||||
* between an interrupt and a task. The semaphore need not be given back once
|
||||
* obtained, so one task/interrupt can continuously 'give' the semaphore while
|
||||
* another continuously 'takes' the semaphore. For this reason this type of
|
||||
* semaphore does not use a priority inheritance mechanism. For an alternative
|
||||
* that does use priority inheritance see xSemaphoreCreateMutex().
|
||||
*
|
||||
* @return Handle to the created semaphore, or NULL if the memory required to

* Counting semaphores are typically used for two things:

|
||||
* 1) Counting events.
|
||||
*
|
||||
* In this usage scenario an event handler will 'give' a semaphore each time
|
||||
* an event occurs (incrementing the semaphore count value), and a handler
|
||||
* task will 'take' a semaphore each time it processes an event
|
||||

* the difference between the number of events that have occurred and the

||||
* number that have been processed. In this case it is desirable for the

* initial count value to be zero.
|
||||
*
|
||||
* 2) Resource management.
|
||||
*
|
||||
* In this usage scenario the count value indicates the number of resources
|
||||
* available. To obtain control of a resource a task must first obtain a
|
||||
* semaphore - decrementing the semaphore count value. When the count value
|
||||
* reaches zero there are no free resources. When a task finishes with the
|
||||
* resource it 'gives' the semaphore back - incrementing the semaphore count
|
||||
* value. In this case it is desirable for the initial count value to be
|
||||
* equal to the maximum count value, indicating that all resources are free.
|

If you find your application is crashing here then likely causes are

more tips, and ensure configASSERT() is defined!
|

https://www.freertos.org/a00110.html#configASSERT
|
||||
|
||||
If you find your application is crashing here then likely causes are:
|
||||
1) Stack overflow -
|
||||
see https://www.freertos.org/Stacks-and-stack-overflow-checking.html
|
||||
2) Incorrect interrupt priority assignment, especially on Cortex-M
|
||||
see http://www.freertos.org/Stacks-and-stack-overflow-checking.html
|
||||
2) Incorrect interrupt priority assignment, especially on Cortex-M3
|
||||
parts where numerically high priority values denote low actual
|
||||
interrupt priorities, which can seem counter intuitive. See
|
||||
https://www.freertos.org/RTOS-Cortex-M3-M4.html and the definition
|
||||
of configMAX_SYSCALL_INTERRUPT_PRIORITY on
|
||||
https://www.freertos.org/a00110.html
|
||||
interrupt priories, which can seem counter intuitive. See
|
||||
configMAX_SYSCALL_INTERRUPT_PRIORITY on http://www.freertos.org/a00110.html
|
||||
3) Calling an API function from within a critical section or when
|
||||
the scheduler is suspended, or calling an API function that does
|
||||
not end in "FromISR" from an interrupt.
|
||||
4) Using a queue or semaphore before it has been initialised or
|
||||
before the scheduler has been started (are interrupts firing
|
||||
before vTaskStartScheduler() has been called?).

||||

microcontroller or compiler, where the directory name denotes the compiler

specific files the directory contains.
|

|

|

|

For example, if you are interested in the [compiler] port for the [architecture]

microcontroller, then the port specific files are contained in
|

FreeRTOS/Source/Portable/[compiler]/[architecture] directory. If this is the

The easiest way to use FreeRTOS is to start with one of the pre-configured demo
|
||||
application projects (found in the FreeRTOS/Demo directory). That way you will
|
||||
have the correct FreeRTOS source files included, and the correct include paths
|

configured. Once a demo application is building and executing you can remove
|
||||
the demo application file, and start to add in your own application source
|

files.

OTA Bootloader (rboot) source module and support files.
|
||||
|
||||
rboot is an open source bootloader by Richard Burton:
|
||||
https://github.com/raburton/rboot
|
||||
|
||||
Can be used to build an esp-open-rtos compatible rboot bootloader. Run 'make bootloader' in this directory to compile a new bootloader.
|
||||
|
||||
Compiling a new bootloader is optional, there's a prebuilt one in the "firmware_prebuilt" directory that will be used if no new bootloader was compiled.
|
||||
|
||||
It is also possible to use rboot from upstream verbatim, but *ensure that the `RBOOT_BIG_FLASH` option is enabled or images in slots other than 0 won't work correctly.
|
||||
|
||||
See the contents of the 'rboot' directory for more information on rboot.

/* ESP GPIO interrupts.
|
||||
|
||||
Use with gpio_set_interrupt(), defined in esp/gpio.h
|
||||
|
||||
These interrupt vectors are default implementations with weak
|
||||
linkage. If you write your own GPIO interrupt vectors in your program
|
||||
then they will replace these at link time.
|
||||
|
||||
Look in examples/button/ for a simple GPIO interrupt example.
|
||||
|
||||
You can implement GPIO interrupt handlers in either of two ways:
|
||||
|
||||
- Implement gpXX_interrupt_handler() for each GPIO pin number that
|
||||
you want to use interrupt with. This is simple but it may not
|
||||
be enough in all cases.
|
||||
|
||||
void gpio01_interrupt_handler(void) {
|
||||
// Do something when GPIO 01 changes
|
||||
}
|
||||
|
||||
void gpio12_interrupt_handler(void) {
|
||||
// Do something when GPIO 12 changes
|
||||
}
|
||||
|
||||
OR
|
||||
|
||||
- Implement a single function named gpio_interrupt_handler(). This
|
||||
will need to manually check GPIO.STATUS and clear any status
|
||||
bits after handling interrupts. This gives you full control, but
|
||||
you can't combine it with the first approach.

that not that not all pins are confirmed to work, GPIO 0 is

confirmed not usable as the SDK configures it as the WLAN_ACTIVE

output - even if you change the pin mode the SDK will change it

back.)

To change pins and have coexistence work successfully the BT

coexistence feature must be enabled in the phy_info configuration

(get_default_phy_info()). You can then modify the initial

configuration by calling this function from your own user_init

function.

to enable coexistence without SDK support at all, but not yet.)

This function will enable bt_active_pin & bt_priority_as GPIO
|

inputs, according to the mode parameter.
|

Remember that the default Bluetooth Coexistence pins will be

Please follow the steps below to build and run the example on your ESP8266.
|
||||
|
||||
1. Modify client_config.c to provide your own account-specific AWS IoT
|
||||
endpoint, ECC-based client certificate, and private key.
|
||||
|
||||
Your endpoint is in the form of ```<prefix>.iot.<region>.amazonaws.com```.
|
||||
It can be retrieved using the following command:
|
||||
|
||||
```sh
|
||||
$ aws iot describe-endpoint
|
||||
```
|
||||
|
||||
Your ECC-based certificate and private key can be generated by using
|
||||
the following commands:
|
||||
|
||||
```sh
|
||||
$ openssl ecparam -out ecckey.key -name prime256v1 -genkey
|
||||
$ openssl req -new -sha256 -key ecckey.key -nodes -out eccCsr.csr
|
||||
$ aws iot create-certificate-from-csr --certificate-signing-request file://eccCsr.csr --certificate-pem-outfile eccCert.crt --set-as-active
|
||||
```
|
||||
|
||||
To convert the certificate or key file into C string, you could try
|
||||
the following example:
|
||||
|
||||
```sh
|
||||
$ cat ecckey.key | sed -e 's/^/"/g' | sed -e 's/$/\\r\\n"/g'
|
||||
```
|
||||
|
||||
*Note, more information about using ECC-based certificate with AWS IoT
|
||||
can be found in the following blog*
|
||||
|
||||
https://aws.amazon.com/blogs/iot/elliptic-curve-cryptography-and-forward-secrecy-support-in-aws-iot-3/
|
||||
|
||||
2. Create and attach AWS IoT access policy to the certificate
|
||||
|
||||
```sh
|
||||
$ aws iot create-policy --policy-name test-thing-policy --policy-document '{ "Version": "2012-10-17", "Statement": [{"Action": ["iot:*"], "Resource": ["*"], "Effect": "Allow" }] }'
|
||||
$ aws iot attach-principal-policy --policy-name test-thing-policy --principal "arn:aws:iot:eu-west-1:892804553548:cert/2d9c2da32a95b5e95a277c3b8f7af40869727f5259dc2e907fc8aba916c857e"
|
||||
```
|
||||
|
||||
*Note, the 'principal' argument is the certificate ARN generated from the
|
||||
pervious command 'aws iot create-certificate-from-csr'.*
|
||||
|
||||
3. Modify include/ssid_config.h with your Wifi access Id and credential.
|
||||
|
||||
4. Build and flash the example firmware to the device using the command
|
||||
below:
|
||||
|
||||
```sh
|
||||
$ make flash -C examples/aws_iot ESPPORT=/dev/ttyUSB0
|
||||
```
|
||||
|
||||
*Note, it assumes your ESP8266 is connected through USB and exposed under
|
||||
your Linux host as /dev/ttyUSB0.*
|
||||
|
||||
5. Once the ESP8266 is connected to AWS IoT, you can use the MQTT client
|
||||
on the AWS IoT console to receive the messages published by the ESP8266
|
||||
to topic 'esp8266/status'. You could also publish 'on' or 'off' message
|
||||
to topic 'esp8266/control' to toggle the GPIO/LED (GPIO2 is used by the
|
||||
example).
