Semaphore

Hi, firstly sorry all for posting so many questions but I’m complete novice!!! I’trying to use the example aboute "mutexes" but the commpiler return: undefined reference to xSemaphoreCreateMutex; I include the headres file : semphr.h and queue.h. The example posted on web page is: http://www.freertos.org/a00122.html Thanks for all!!!!

Have you set configUSE_MUTEXES to 1 in FreeRTOSConfig.h?  You might need to add the definition in, if it is omitted it will get defaulted to 0. Regards.
