*** 0.3.4 ***
- Fixed a problem in chVTSetI().
- Modified chEvtWaitTimeout() to work correctly in the TIME_INFINITE
scenario.
- New API, chVTIsArmedI(), it is a macro in delta.h.
- New API, chThdResumeI(), it is a macro in threads.h. This function is just
an alias for chSchReadyI() but makes the code more readable.
- New API, chThdSuspend(). New switch CH_USE_SUSPEND added to chconf.h.
*** 0.3.3 ***
- Modified the chVTSetI(), now for the "time" parameter can have value zero
with meaning "infinite". This allows all the APIs with timeout parameters
@ -54,7 +56,7 @@ AVR-AT90CANx-GCC - Port on AVER AT90CAN128, not complete yet.
- Modified the chSysInit() to give the idle thread absolute priority, the
priority is then lowered to the minimum value into the chSysPause(). This
is done in order to ensure that the initializations performed into the
main() procedure are performed before any thread starts.
main() procedure are finished before any thread starts.
- Added chThdSetPriority() new API.
- Added a generic events generator timer modulee to the library code.
- Modified the ARM7-LPC214x-GCC demo to show the use of the event timer.
