This demo creates three tasks all of which access the same recursive mutex:
|

prvRecursiveMutexControllingTask() has the highest priority so executes

first and grabs the mutex. It then performs some recursive accesses -

prvRecursiveMutexControllingTask() has the highest priority so executes
|
||||
first and grabs the mutex. It then performs some recursive accesses -
|
||||
between each of which it sleeps for a short period to let the lower
|
||||
priority tasks execute. When it has completed its demo functionality
|
||||
it gives the mutex back before suspending itself.
|
||||
|
||||
prvRecursiveMutexBlockingTask() attempts to access the mutex by performing
|
||||
a blocking 'take'. The blocking task has a lower priority than the

a blocking 'take'. The blocking task has a lower priority than the
|

controlling task so by the time it executes the mutex has already been

does not unblock until the controlling task has given the mutex back,

itself (due to the relative priorities). When it eventually does obtain

itself. At this point both the controlling task and the blocking task are

suspended.
|
||||
|

prvRecursiveMutexPollingTask() runs at the idle priority. It spins round
|
||||
a tight loop attempting to obtain the mutex with a non-blocking call. As
|
||||
the lowest priority task it will not successfully obtain the mutex until
|
||||
both the controlling and blocking tasks are suspended. Once it eventually
|
||||
both the controlling and blocking tasks are suspended. Once it eventually
|
||||
does obtain the mutex it first unsuspends both the controlling task and
|
||||
blocking task prior to giving the mutex back - resulting in the polling
|
||||
task temporarily inheriting the controlling tasks priority.
