I would like to invoke a hardware interruption whenever there is a change in the PLU Inputs values (PLU_INs).
I have used the NVIC_EnableIRQ() from the CMSIS access NVIC functions.
Also I checked the PLU interrupt priority and it is 0.
But whenever I change the PLU_IN values, (from 0V to ), nothing occurs, no execution of the PLU_IRQHandler(). No interruption happen. I tried to manually pend the interruption (using the SW) only then the PLU_IRQHandler() is executed.
Any idea about what I maybe missing?
Any example deploying interruptions?
When does the SysTick has to do with peripheral interruption?
Thank you in advance.
