Kernel changes:
- Remove an assert that was preventing xQueueSendFromISR() being used to give a mutex from an ISR (mutexes cannot be given using xSemaphoreGiveFromISR()).
- Introduce xTaskNotifyAndQueryFromISR() as the interrupt safe version of xTaskNotifyAndQuery().
Common demo task changes:
- Update IntSemTest.c to prove the theory that it is safe to give a mutex type semaphore from an interrupt using xQueueSendFromISR() instead of xSemaphoreGiveFromISR().
- Update TaskNotify.c to test the new xTaskNotifyAndQuery() from ISR fuction.
Links to a documentation page for each demo are provided on the following
URL: http://www.freertos.org/a00090.html
Each RTOS port has a demo application to demonstrate it's use.
+ The Demo/Common directory contains the demo application files as described on
the http://www.FreeRTOS.org WEB site. Each file creates one or more tasks.
The files in the Demo/Common directory are used by every demo application for
every port.
+ All the other directories contain a project or makefile for the demo
application targeted at a particular microcontroller.
For example, if you are interested in the ATMega323 demo application for
the WinAVR tools then the AVR_ATMega323_WinAVR directory contains the
relevant makefile. The makefile includes files from the Demo/ATMega323
and the Demo/Common directories. If this is the only port you are
interested in then all the other directories can be ignored.
