Enable/Disable Interrupts on one pin only. Leave the others enabled.

Keith asked 2 years ago

I want to have interrupts always enabled on one pin but want to enable and disable interrupts on another pin. I understand how to enable and disable interrupts but I don’t want to do that for some of the pins that I have interrupt enabled all of the time. Do you have any advice on how to do this? Thanks for your time.

Hi.
Have you taken a look at the detachInterrupt() function? It accepts as an argument the GPIO you want to disable the interrupt:

detachInterrupt(GPIOPin);

I hope this helps.
