How do we step out of a "lock zone"?

[ceremcem]

I'm trying to implement a debounce logic with the following procedure:

1. Define an input callback (button_callback) and register it when the application starts.
2. When an interrupt is received, disable the pad event on that pad inside this interrupt handler (button_callback)
3. Wait for a debounce time (100ms, for example)
4. Enable the pad event
5. Return from button_callback function.

However, this logic isn't working because documentation says:

Code: Select all

palDisablePadEvent

Function Class:Normal API, this function can be invoked by regular system threads but not from within a lock zone.

How can we step out of the lock zone so that we could implement this logic?

Look at palDisableLineEventI().
