 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.

-ARM7-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. Full demo.

-ARM7-LPC214x-GCC-min - Minimal demo for LPC214X.

-AVR-AT90CANx-GCC     - Port on AVR AT90CAN128, not complete yet.

   chEvtWaitTimeout() code if it is enabled.

 - Size optimization in the semaphores code, now the chSemWaitTimeout() just

   invokes the chSemWaitTimeoutS() inside its system mutex zone.

+- Added a threads create/exit/wait benchmark to the test suite, the system

+  is capable of 81712 threads started/terminated per second on the reference

+  LPC2148 board. The figure is inclusive of two context switch operations

+  for each thread.

 - Minor improvement in the LPC214x serial driver, unneeded events were

   generated in some rare cases.

 - Fixed a chSysInit() documentation error.
