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.

Make sure configUSE_COUNTING_SEMAPHORES is set to 1 in FreeRTOSConfig.h

adding:

#define configUSE_COUNTING_SEMAPHORES 1 

helped. Now everything is working properly 😀
Thank you.
