included to allow you to distribute a combined work that includes FreeRTOS
without being obliged to provide the source code for any proprietary
components. See the licensing section of http://www.FreeRTOS.org for full
details. The exception text is also included at the bottom of this file.
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.
The FreeRTOS download also includes demo application source code, some of
which is provided by third parties AND IS LICENSED SEPARATELY FROM FREERTOS.

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).
1) Various header files provided by silicon manufacturers and tool vendors
that define processor specific memory addresses and utility macros.
Permission has been granted by the various copyright holders for these
files to be included in the FreeRTOS download. Users must ensure license
conditions are adhered to for any use other than compilation of the
FreeRTOS demo applications.
2) The uIP TCP/IP stack the copyright of which is held by Adam Dunkels.
Users must ensure the open source license conditions stated at the top
of each uIP source file is understood and adhered to.
3) The lwIP TCP/IP stack the copyright of which is held by the Swedish
Institute of Computer Science. Users must ensure the open source license
conditions stated at the top of each lwIP source file is understood and
adhered to.
4) Various peripheral driver source files and binaries provided by silicon
manufacturers and tool vendors. Permission has been granted by the
various copyright holders for these files to be included in the FreeRTOS
download. Users must ensure license conditions are adhered to for any
use other than compilation of the FreeRTOS demo applications.
5) The files contained within FreeRTOS\Demo\WizNET_DEMO_TERN_186\tern_code,
which are slightly modified versions of code provided by and copyright to
Tern Inc.

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

* Receive an item from a queue. The item is received by copy so a buffer of
* adequate size must be provided. The number of bytes copied into the buffer
* was defined when the queue was created.
*
* This function must not be used in an interrupt service routine. See
* xQueueReceiveFromISR for an alternative that can.
*
* @param xQueue The handle to the queue from which the item is to be
* received.
*
* @param pvBuffer Pointer to the buffer into which the received item will
* be copied.
*
* @param xTicksToWait The maximum amount of time the task should block
* waiting for an item to receive should the queue be empty at the time
* of the call. The time is defined in tick periods so the constant
* portTICK_PERIOD_MS should be used to convert to real time if this is required.
* xQueueGenericReceive() will return immediately if the queue is empty and
* xTicksToWait is 0.
*
* @param xJustPeek When set to true, the item received from the queue is not
* actually removed from the queue - meaning a subsequent call to
* xQueueReceive() will return the same item. When set to false, the item
* being received from the queue is also removed from the queue.
*
* @return pdTRUE if an item was successfully received from the queue,
* otherwise pdFALSE.
*
* Example usage:

Each real time kernel port consists of three files that contain the core kernel
components and are common to every port, and one or more files that are
specific to a particular microcontroller and/or compiler.
+ The FreeRTOS/Source/Portable/MemMang directory contains the five sample
memory allocators as described on the http://www.FreeRTOS.org WEB site.
+ 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.

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