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

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

The FreeRTOS GPL Exception Text:
|
||||
|
||||
Any FreeRTOS source code, whether modified or in it's original release form,
|
||||
or whether in whole or in part, can only be distributed by you under the terms
|
||||
of the GNU General Public License plus this exception. An independent module is
|
||||
a module which is not derived from or based on FreeRTOS.
|
||||
|
||||
Clause 1:
|
||||
|
||||
Linking FreeRTOS statically or dynamically with other modules is making a
|
||||
combined work based on FreeRTOS. Thus, the terms and conditions of the GNU
|
||||
General Public License cover the whole combination.
|
||||
|
||||
As a special exception, the copyright holder of FreeRTOS gives you permission

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 end of the list and acts as a marker. The list member pxHead always
|
||||
* points to this marker - even though it is at the tail of the list. This
|
||||
* is because the tail contains a wrap back pointer to the true head of
|
||||
* the list.
|
||||
*
|
||||
* In addition to it's value, each list item contains a pointer to the next

* <i>Macro</i> that implements a semaphore by using the existing queue mechanism.

* The queue length is 1 as this is a binary semaphore. The data size is 0

*
|

* 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
|

|

* <i>Macro</i> that creates a counting semaphore by using the existing

|
||||
*
|
||||
* 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
|
||||
* equal to the maximum count value, indicating that all resources are free.
|
||||
*
|
||||
* @param uxMaxCount The maximum count value that can be reached. When the

* Creates a new software timer instance. This allocates the storage required

* handle by which the new timer can be referenced.
|
||||
*

* 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.
|

* which is "void vCallbackFunction( xTimerHandle xTimer );".

/**

* portBASE_TYPE xTimerReset( xTimerHandle xTimer, portTickType xBlockTime );
|
||||
*
|
||||
* Timer functionality is provided by a timer service/daemon task. Many of the
|
||||
* public FreeRTOS timer API functions send commands to the timer service task
|
||||
* though a queue called the timer command queue. The timer command queue is
|
||||
* private to the kernel itself and is not directly accessible to application
|
||||
* code. The length of the timer command queue is set by the
|
||||
* configTIMER_QUEUE_LENGTH configuration constant.
|
||||
*
|
||||
* xTimerReset() re-starts a timer that was previously created using the
|
||||
* xTimerCreate() API function. If the timer had already been started and was
|
||||
* already in the active state, then xTimerReset() will cause the timer to
|
||||
* re-evaluate its expiry time so that it is relative to when xTimerReset() was
|
||||
* called. If the timer was in the dormant state then xTimerReset() has
|
||||
* equivalent functionality to the xTimerStart() API function.
|
||||
*
|
||||
* Resetting a timer ensures the timer is in the active state. If the timer
|
||||
* is not stopped, deleted, or reset in the mean time, the callback function
|
||||
* associated with the timer will get called 'n' ticks after xTimerReset() was
|
||||
* called, where 'n' is the timers defined period.
|
||||
*
|
||||
* It is valid to call xTimerReset() before the scheduler has been started, but
|
||||
* when this is done the timer will not actually start until the scheduler is
|
||||
* started, and the timers expiry time will be relative to when the scheduler is
|
||||
* started, not relative to when xTimerReset() was called.
|
||||
*
|
||||
* The configUSE_TIMERS configuration constant must be set to 1 for xTimerReset()
|
||||
* to be available.
|
||||
*
|
||||
* @param xTimer The handle of the timer being reset/started/restarted.
|
||||
*
|
||||
* @param xBlockTime Specifies the time, in ticks, that the calling task should
|
||||
* be held in the Blocked state to wait for the reset command to be successfully
|
||||
* sent to the timer command queue, should the queue already be full when
|
||||
* xTimerReset() was called. xBlockTime is ignored if xTimerReset() is called
|
||||
* before the scheduler is started.
|
||||
*
|
||||
* @return pdFAIL will be returned if the reset command could not be sent to
|
||||
* the timer command queue even after xBlockTime ticks had passed. 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 xTimerStart() is actually called. The
|

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

1) Stack overflow -

see http://www.freertos.org/Stacks-and-stack-overflow-checking.html
|
||||
2) Incorrect interrupt priority assignment, especially on Cortex-M3
|

parts where numerically high priority values denote low actual
|
||||
interrupt priories, which can seem counter intuitive. See
|
||||
configMAX_SYSCALL_INTERRUPT_PRIORITY on http://www.freertos.org/a00110.html
|
||||
3) Calling an API function from within a critical section or when
|

the scheduler is suspended.
|
||||
4) Using a queue or semaphore before it has been initialised or
|
||||
before the scheduler has been started (are interrupts firing
|

before vTaskStartScheduler() has been called?).
|

See http://www.freertos.org/FAQHelp.html for more tips.

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 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/include directory contains the real time kernel header
|
||||
files.

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.

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.
