    The differences between binary semaphore and mutex are very simple:

    - Mutex is used exclusively for mutual exclusion. Both mutual exclusion and synchronization can be used by binary.
    - A task that took mutex can only give mutex.
    - From an ISR a mutex cannot be given.
    - Recursive taking of mutual exclusion semaphores is possible. This means that a task that holds before finally releasing a semaphore, can take the semaphore more than once.
    - Options for making the task which takes as DELETE_SAFE are provided by Mutex, which means the task deletion is not possible when holding the mutex.
