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.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
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 kernel is released under the MIT open source license, the text of
which is provided below.
This license covers the FreeRTOS kernel source files, which are located in the
/FreeRTOS/Source directory of the official FreeRTOS kernel 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.

For esp-open-rtos, you can override settings in here by creating your own
FreeRTOSConfig.h file in your program directory. You could just copy this
file there and edit it, but it's recommended you instead define whatever you
want to override and then use #include_next<FreeRTOSConfig.h> to pick up
these defaults. The "blink" example in "examples/blink" provides an example
of how to do this.

* 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).

* Interrupt safe version of the API function that sends a stream of bytes to

*
* ***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 xStreamBufferSend()) 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 xStreamBufferRead()) inside a critical section and set the receive
* block time to 0.
*
* Use xStreamBufferSend() to write to a stream buffer from a task. Use

*
* @param pvTxData A pointer to the data that is to be copied into the stream
* buffer.
*
* @param xDataLengthBytes The maximum number of bytes to copy from pvTxData

*
* @param pxHigherPriorityTaskWoken It is possible that a stream buffer will
* have a task blocked on it waiting for data. Calling
* xStreamBufferSendFromISR() can make data available, and so cause a task that
* was waiting for data to leave the Blocked state. If calling
* xStreamBufferSendFromISR() 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, xStreamBufferSendFromISR()
* will set *pxHigherPriorityTaskWoken to pdTRUE. If
* xStreamBufferSendFromISR() 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 example code below for an example.

Each real time kernel port consists of three files that contain the core kernel

specific to a particular microcontroller and or compiler.
+ 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.
+ The FreeRTOS/Source/include directory contains the real time kernel header
files.
See the readme file in the FreeRTOS/Source/Portable directory for more
information.

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.
