./src/templates/ - ChibiOS/RT non portable source templates, new ports

are started by copying the templates into a new

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. The test performs integrity tests on the main
|
|
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
