a two short questions.
a) How can i free the allocated memory of a semaphore handle?
xSemaphoreHandle myHandle = xSemaphoreCreateMutex();
ToDo: How to free the allocated memory?
b) Why does this handle allocate 0x58 bytes?

a) All semaphore functionality is built on top of queue functionality, so you can use the queue delete function to delete a semaphore too. Be careful that no tasks hold the semaphore or are blocked on the semaphore before it is deleted though.
b) See the FAQ "why does a queue use that much RAM" http://www.freertos.org/FAQMem.html It is not just the handle, but the entire semaphore.
