*****************************************************************************
*** Directories structure ***
*****************************************************************************
./readme.txt - This file.
./license.txt - GPL3 license file.
./src/ - ChibiOS/RT portable kernel source files.
./src/include/ - ChibiOS/RT include files.
./src/templates/ - ChibiOS/RT non portable source templates, new ports
are started by copying the templates into a new
directory under ./demos/.
./ports/ - Architecture/compiler specific portable files.
./demos/ - Demo programs for specific archtectures/boards.
./test/ - Test code, used by some demos.
./docs/Doxifile - Doxigen project file.
./docs/html/index.html - ChibiOS/RT documentation (after running doxigen).
The documentation is also available on the project
web page: http://chibios.sourceforge.net/
Current ports under ./demos:
Win32-MinGW - ChibiOS/RT simulator and demo into a WIN32 process,
MinGW version.
Win32-MSVS - ChibiOS/RT simulator and demo into a WIN32 process,
Visual Studio 7 or any later version should work.
LPC214x-GCC - ChibiOS/RT port for ARM7 LPC2148, the demo targets the
Olimex LPC-P2148 board. This port can be easily modified
for any processor into the LPC2000 family or other
boards. The demo can be compiled using YAGARTO or any
other GCC-based ARM toolchain.
*****************************************************************************
*** Releases ***
*****************************************************************************
*** 0.3.1 ***
- Test program added to the demos. Telnet the MinGW and MSVS demos and type
"test" at the "ch>" prompt. On the LPC214x demo the test is activated by
pressing both the board buttons. The test performs tests on the ChibiOS/RT
functionalities.
The test code is also a good example of APIs usage and ChibiOS/RT behavior.
- Fixed bug in chEvtWaitTimeout(), the timeout code performed an useless
dequeue operation.
- Fixed a bug in chSemWaitTimeoutS() and chSemWaitTimeout(), the semaphore
counter was not atomically updated on a timeout condition.
- Fixed bug on RT semaphores, the priority queuing was broken.
- Fixed a bug in the MinGW demo, the chThdExit() code was not correctly
reported to the thread waiting in chThdWait().
- Fixed a function declaration in semaphores.h.
- Lists code moved into chlists.c from various other places optimized and
reorganized.
- The list of the threads waiting in chThdWait() is now a single link list,
this saves some space.
- Cleaned the template files code, the files contained some obsolete
declarations.
- Code optimization in chSemWaitTimeoutS(), chSemWaitTimeout() and
chSemSignalWait().
- Code optimization in chEvtSend().
- Code optimization in chVTDoTickI().
- Added a Semaphore pointer to the Thread structure, this allows to know on
which semaphore a thread is waiting on. It takes no space because it is
located in the union inside the Thread structure. This also allowed a minor
optimization inside chSemWaitTimeout() and chSemWaitTimeoutS().
- Changed the priority type to unsigned in order to make it compatible
with a byte value, this is very important for 8 bits architectures.
- Modified the MinGW and MSVS demos to use 1ms ticks instead of 10ms as
before.
*** 0.3.0 ***
- ChibiOS/RT goes beta.
- Diet for the threads code, some simple APIs become macros.
- Thread Local Storage implemented as a single API: chThdLS().
The API simply returns a pointer into the thread working area, see the
documentation on the web site.
- Moved some documentation and images from the web site into the Doxigen
generated HTMLs.
*** 0.2.1 ***
- Optimizations in the RT semaphores subsystem. The support for this
subsystem should still be considered experimental and further changes may
happen in future versions.
- Bug fix in the virtual timers handling code, now the timers can be re-armed
from within the callback code in order to create periodic virtual timers.
- Modified the t_prio type in the demos to be 32bits wide instead of 16bits,
this results in a better code in critical sections of the kernel.
*** 0.2.0 ***
- Introduced support for ARM in thumb mode.
- Optimized context switching when thumb-interworking is not required, one
less instruction.
- Minor fixes to the ARM demo.
*** 0.1.1 ***
- Some fixes into the documentation
- Renamed makefiles to Makefiles, upper case M.
*** 0.1.0 ***
- First alpha release
