Abstraction for uC/OS OS_EVENT? #10

Open msplr opened 10 years ago

msplr commented 10 years ago

Will OS_EVENT's be used?

antoinealb commented 10 years ago

Well OS_EVENT is a generic type used for mutex, semaphore and various other features. So what do you mean ?

Not anymore in uC/OS-III. But still: Could you elaborate?

right. I meant OSEventPendMulti(). Being able to wait for multiple "events" at once is sometimes very useful, but it is probably difficult to abstract and test this.

Not anymore in uC/OS-III.

ok, didn't know. I was looking at uC/OS-II documentation.

They started to make actual types like OS_MUTEX and OS_SEM.

OSEventPendMulti() seems really useful to me, too.

The new API.

This seems pretty useful and could be abstracted into something like this maybe (function name not appropriate) :

semaphore_t *os_semaphore_take_many(semaphore_t *semaphores[], size_t count);

The function would return the semaphore that was accepted. Now if we want to add message queues into the mix, we probably should define an abstraction for message queues first.
