Hi,
I have to switch some relays and so I have to wait until this relays stop bouncing. Ok, I will have a sequence like this:
switchRelays(); // not blocking
switchOtherRelays(); // not blocking
prepareSomethingElse(); // not blocking
// Wait until all semaphores or mutexes or whatever were free e.g. given
if ( getWhatEverSemaphoreOrMutex() == true
{ start out working
}
Problem:
This is going on in one task. Semaphores and Mutexes were for sync between tasks.
How can I do this best?
I don’t understand what you are using the semaphores for. What is giving the semaphores? An interrupt that executes a service routine when the relays stop bouncing?
Hi,
I take a semaphore, switch the relays and start a timer, one shot. After this timer expires the semaphore is given in a callback.
Using recursive semaphores would allow to take the semaphore more then once (more than one relay, different relay types, different bouncing time …) and block the work until all semaphores were given in the timers callbacks.
