+ 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 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).

+ * as we don't want to actually store any data - we just want to know if the
+ * queue is empty or full.
+ *
+ * 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().
+ *
+ * @param xSemaphore Handle to the created semaphore. Should be of type xSemaphoreHandle.
+ *
+ * Example usage:
+ <pre>
+ xSemaphoreHandle xSemaphore;
+
+ void vATask( void * pvParameters )
+ {
+ // Semaphore cannot be used before a call to vSemaphoreCreateBinary ().

+ *
+ * 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
+ * (decrementing the semaphore count value). The count value is therefore
+ * 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

+ *
+ * Creates a new software timer instance. This allocates the storage required
+ * by the new timer, initialises the new timers internal state, and returns a
+ * handle by which the new timer can be referenced.
+ *
+ * Timers are created in the dormant state. The xTimerStart(), xTimerReset(),
+ * xTimerStartFromISR(), xTimerResetFromISR(), xTimerChangePeriod() and
+ * xTimerChangePeriodFromISR() API functions can all be used to transition a timer into the

+ *
+ * @param pcTimerName A text name that is assigned to the timer. This is done
+ * purely to assist debugging. The kernel itself only ever references a timer by
+ * its handle, and never by its name.
+ *
+ * @param xTimerPeriodInTicks The timer period. The time is defined in tick periods so
+ * the constant portTICK_RATE_MS can be used to convert a time that has been
+ * specified in milliseconds. For example, if the timer must expire after 100
+ * ticks, then xTimerPeriodInTicks should be set to 100. Alternatively, if the timer
+ * must expire after 500ms, then xPeriod can be set to ( 500 / portTICK_RATE_MS )
+ * provided configTICK_RATE_HZ is less than or equal to 1000.
+ *
+ * @param uxAutoReload If uxAutoReload is set to pdTRUE then the timer will
+ * expire repeatedly with a frequency set by the xTimerPeriodInTicks parameter. If
+ * uxAutoReload is set to pdFALSE then the timer will be a one-shot timer and
+ * enter the dormant state after it expires.
+ *
+ * @param pvTimerID An identifier that is assigned to the timer being created.
+ * Typically this would be used in the timer callback function to identify which
+ * timer expired when the same callback function is assigned to more than one
+ * timer.
+ *
+ * @param pxCallbackFunction The function to call when the timer expires.
+ * Callback functions must have the prototype defined by tmrTIMER_CALLBACK,
+ * which is "void vCallbackFunction( xTimerHandle xTimer );".

+ * portBASE_TYPE xTimerResetFromISR( xTimerHandle xTimer,

+ *
+ * A version of xTimerReset() that can be called from an interrupt service
+ * routine.
+ *
+ * @param xTimer The handle of the timer that is to be started, reset, or
+ * restarted.
+ *
+ * @param pxHigherPriorityTaskWoken The timer service/daemon task spends most
+ * of its time in the Blocked state, waiting for messages to arrive on the timer
+ * command queue. Calling xTimerResetFromISR() writes a message to the timer
+ * command queue, so has the potential to transition the timer service/daemon
+ * task out of the Blocked state. If calling xTimerResetFromISR() causes the
+ * timer service/daemon task to leave the Blocked state, and the timer service/
+ * daemon task has a priority equal to or greater than the currently executing
+ * task (the task that was interrupted), then *pxHigherPriorityTaskWoken will
+ * get set to pdTRUE internally within the xTimerResetFromISR() function. If
+ * xTimerResetFromISR() sets this value to pdTRUE then a context switch should
+ * be performed before the interrupt exits.
+ *
+ * @return pdFAIL will be returned if the reset command could not be sent to
+ * the timer command queue. pdPASS will be returned if the command was
+ * successfully sent to the timer command queue. When the command is actually
+ * processed will depend on the priority of the timer service/daemon task
+ * relative to other tasks in the system, although the timers expiry time is
+ * relative to when xTimerResetFromISR() is actually called. The timer service/daemon
+ * task priority is set by the configTIMER_TASK_PRIORITY configuration constant.
+ *
+ * Example usage:
+ *
+ * // This scenario assumes xBacklightTimer has already been created. When a
+ * // key is pressed, an LCD back-light is switched on. If 5 seconds pass
+ * // without a key being pressed, then the LCD back-light is switched off. In
+ * // this case, the timer is a one-shot timer, and unlike the example given for
+ * // the xTimerReset() function, the key press event handler is an interrupt
+ * // service routine.
+ *
+ * // The callback function assigned to the one-shot timer. In this case the
+ * // parameter is not used.
+ * void vBacklightTimerCallback( xTimerHandle pxTimer )
+ * {
+ * // The timer expired, therefore 5 seconds must have passed since a key
+ * // was pressed. Switch off the LCD back-light.
+ * vSetBacklightState( BACKLIGHT_OFF );
+ * }
+ *
+ * // The key press interrupt service routine.
+ * void vKeyPressEventInterruptHandler( void )
+ * {
+ * portBASE_TYPE xHigherPriorityTaskWoken = pdFALSE;
+ *
+ * // Ensure the LCD back-light is on, then reset the timer that is
+ * // responsible for turning the back-light off after 5 seconds of
+ * // key inactivity. This is an interrupt service routine so can only
+ * // call FreeRTOS API functions that end in "FromISR".
+ * vSetBacklightState( BACKLIGHT_ON );
+ *
+ * // xTimerStartFromISR() or xTimerResetFromISR() could be called here
+ * // as both cause the timer to re-calculate its expiry time.
