The FreeRTOS open source license covers the FreeRTOS source files,
|
||||
which are located in the /FreeRTOS/Source directory of the official FreeRTOS
|
||||
download. It also covers most of the source files in the demo application
|
||||
projects, which are located in the /FreeRTOS/Demo directory of the official
|
||||
FreeRTOS download. The demo projects may also include third party software that
|
||||
is not part of FreeRTOS and is licensed separately to FreeRTOS. Examples of
|
||||
third party software includes header files provided by chip or tools vendors,
|
||||
linker scripts, peripheral drivers, etc. All the software in subdirectories of
|
||||
the /FreeRTOS directory is either open source or distributed with permission,
|
||||
and is free for use. For the avoidance of doubt, refer to the comments at the
|
||||
top of each source file.
|
||||
|
||||
----------------------------------------------------------------------------
|
||||
|
||||
NOTE: The modification to the GPL is included to allow you to distribute a
|
||||
combined work that includes FreeRTOS without being obliged to provide the source
|
||||
code for proprietary components.
|
||||
|
||||
----------------------------------------------------------------------------
|
||||
|
||||
Applying to FreeRTOS V8.2.3 up to the latest version, the FreeRTOS GPL Exception
|
||||
Text follows:
|
||||
|
||||
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 with other modules is making a combined work based on FreeRTOS.
|
||||
Thus, the terms and conditions of the GNU General Public License V2 cover the
|
||||
whole combination.
|
||||
|
||||
As a special exception, the copyright holders of FreeRTOS give you permission to
|
||||
link FreeRTOS with independent modules to produce a statically linked
|
||||
executable, regardless of the license terms of these independent modules, and to
|
||||
copy and distribute the resulting executable under terms of your choice,
|
||||
provided that you also meet, for each linked independent module, the terms and
|
||||
conditions of the license of that module. An independent module is a module
|
||||
which is not derived from or based on 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).

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.

|
||||
covers most of the source files in the demo application projects, which are

and is licensed separately to FreeRTOS. Examples of third party software
|
||||
includes header files provided by chip or tools vendors, linker scripts,

* Message buffers build functionality on top of FreeRTOS stream buffers.
|
||||
* Whereas stream buffers are used to send a continuous stream of data from one
|
||||
* task or interrupt to another, message buffers are used to send variable
|
||||
* length discrete messages from one task or interrupt to another. Their
|
||||
* implementation is light weight, making them particularly suited for interrupt
|
||||
* to task and core to core communication scenarios.
|
||||
*
|
||||
* ***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).

|
||||
* ***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 xMessageBufferSend() to write to a message buffer from a task. Use
|
||||
* xMessageBufferSendFromISR() to write to a message buffer from an interrupt
|
||||
* service routine (ISR).

* message buffer.
|
||||
*
|
||||
* @param xDataLengthBytes The length of the message. That is, the number of
|
||||
* bytes to copy from pvTxData into the message buffer. When a message is
|
||||
* written to the message buffer an additional sizeof( size_t ) bytes are also
|
||||
* written to store the message's length. sizeof( size_t ) is typically 4 bytes
|
||||
* on a 32-bit architecture, so on most 32-bit architecture setting
|
||||
* xDataLengthBytes to 20 will reduce the free space in the message buffer by 24
|
||||
* bytes (20 bytes of message data and 4 bytes to hold the message length).
|
||||
*
|
||||
* @param pxHigherPriorityTaskWoken It is possible that a message buffer will
|
||||
* have a task blocked on it waiting for data. Calling
|
||||
* xMessageBufferSendFromISR() can make data available, and so cause a task that
|
||||
* was waiting for data to leave the Blocked state. If calling
|
||||
* xMessageBufferSendFromISR() 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, xMessageBufferSendFromISR()
|
||||
* will set *pxHigherPriorityTaskWoken to pdTRUE. If
|
||||
* xMessageBufferSendFromISR() sets this value to pdTRUE, then normally a
|
||||
* context switch should be performed before the interrupt is exited. This will
|
||||
* ensure that 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 number of bytes actually written to the message buffer. If the
|
||||
* message buffer didn't have enough free space for the message to be stored

|

*
|

* The sbRECEIVE_COMPLETED() macro is called from within the FreeRTOS APIs when
|
||||
* data is read out of a message buffer or stream buffer. If there was a task
|
||||
* that was blocked on the message or stream buffer waiting for data to arrive
|
||||
* then the sbRECEIVE_COMPLETED() macro sends a notification to the task to
|
||||
* remove it from the Blocked state. xMessageBufferReceiveCompletedFromISR()
|
||||
* does the same thing. It is provided to enable application writers to
|
||||
* implement their own version of sbRECEIVE_COMPLETED(), and MUST NOT BE USED AT
|
||||
* ANY OTHER TIME.
|
||||
*
|
||||
* See the example implemented in FreeRTOS/Demo/Minimal/MessageBufferAMP.c for
|
||||
* additional information.

||||
* @param xStreamBuffer The handle of the stream buffer from which data was
|
||||
* read.
|
||||
*
|
||||
* @param pxHigherPriorityTaskWoken *pxHigherPriorityTaskWoken should be
|
||||
* initialised to pdFALSE before it is passed into
|
||||
* xMessageBufferReceiveCompletedFromISR(). If calling
|
||||
* xMessageBufferReceiveCompletedFromISR() removes a task from the Blocked state,
|
||||
* and the task has a priority above the priority of the currently running task,
|
||||
* then *pxHigherPriorityTaskWoken will get set to pdTRUE indicating that a
|
||||
* context switch should be performed before exiting the ISR.
|
||||
*
|
||||
* @return If a task was removed from the Blocked state then pdTRUE is returned.
|
||||
* Otherwise pdFALSE is returned.

* FreeRTOS objects, it is not safe to have multiple different writers or

* For advanced users only.
|
||||
*
|
||||
* The sbRECEIVE_COMPLETED() macro is called from within the FreeRTOS APIs when
|
||||
* data is read out of a message buffer or stream buffer. If there was a task
|
||||
* that was blocked on the message or stream buffer waiting for data to arrive
|
||||
* then the sbRECEIVE_COMPLETED() macro sends a notification to the task to
|
||||
* remove it from the Blocked state. xStreamBufferReceiveCompletedFromISR()
|
||||
* does the same thing. It is provided to enable application writers to
|
||||
* implement their own version of sbRECEIVE_COMPLETED(), and MUST NOT BE USED AT
|
||||
* ANY OTHER TIME.
|
||||
*
|
||||
* See the example implemented in FreeRTOS/Demo/Minimal/MessageBufferAMP.c for
|
||||
* additional information.
|
||||
*
|
||||
* @param xStreamBuffer The handle of the stream buffer from which data was
|
||||
* read.
|
||||
*
|
||||
* @param pxHigherPriorityTaskWoken *pxHigherPriorityTaskWoken should be
|
||||
* initialised to pdFALSE before it is passed into
|
||||
* xStreamBufferReceiveCompletedFromISR(). If calling
|
||||
* xStreamBufferReceiveCompletedFromISR() removes a task from the Blocked state,
|
||||
* and the task has a priority above the priority of the currently running task,
|
||||
* then *pxHigherPriorityTaskWoken will get set to pdTRUE indicating that a
|
||||
* context switch should be performed before exiting the ISR.
|
||||
*
|
||||
* @return If a task was removed from the Blocked state then pdTRUE is returned.
|
||||
* Otherwise pdFALSE is returned.

components and are common to every port, and one or more files that are

|

|

+ The FreeRTOS/Source directory contains the three files that are common to
|
||||
every port - list.c, queue.c and tasks.c. The kernel is contained within these
|
||||
three files. croutine.c implements the optional co-routine functionality - which
|
||||
is normally only used on very memory limited systems.
|
||||
|
||||
+ The FreeRTOS/Source/Portable/MemMang directory contains the five sample
|

memory allocators as described on the http://www.FreeRTOS.org WEB site.
|
||||
+ The FreeRTOS/Source/Portable directory contains the files that are specific to
|

a particular microcontroller and or compiler.
|
||||
|
||||
+ The other directories each contain files specific to a particular
|
||||
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
|

only port you are interested in then all the other directories can be

||||
ignored.
|

Directories:
|
||||
|
||||
+ The FreeRTOS/Source directory contains the FreeRTOS source code, and contains
|
||||
its own readme file.
|
||||
|
||||
+ The FreeRTOS/Demo directory contains a demo application for every official
|
||||
FreeRTOS port, and contains its own readme file.
|
||||
|
||||
+ See http://www.freertos.org/a00017.html for full details of the directory
|

structure and information on locating the files you require.
|

|
||||
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.
