what is difference between semaphore and mutex in freertos ?

Question

Accepted Answer

Semaphores allow multiple tasks to access a shared resource, while mutexes only allow one task at a time to access the resource.

Semaphores can have a count greater than 1, allowing multiple tasks to access a shared resource simultaneously.
Mutexes have a count of 1, ensuring only one task can access the resource at a time.
Semaphores are typically used for signaling between tasks, while mutexes are used for exclusive access to resources.
Example: A semaphore could be used to control access to a shared buffer between multiple tasks, while a mutex could be used to protect a critical section of code from concurrent access.
