Problem with creating counting semaphore.Posted by buka86 on December 27, 2011 Hi I have some problems with creating counting semaphore in my project (binary works great). {xSemaphoreHandle xSemaphoreTimer;//Semaphore for Timer 1}{xSemaphoreTimer = xSemaphoreCreateCounting( 5, 0 );}and after this instruction i have linker error: "Error: L6218E: Undefined symbol xQueueCreateCountingSemaphore (referred from main.o)." Please help me to solve it. RE: Problem with creating counting semaphore.Posted by MEdwards on December 27, 2011 Make sure configUSE_COUNTING_SEMAPHORES is set to 1 in FreeRTOSConfig.h RE: Problem with creating counting semaphore.Posted by buka86 on December 27, 2011 adding: #define configUSE_COUNTING_SEMAPHORES 1 helped. Now everything is working properly :D Thank you.
