Single ISR for different interrupt sources

keyboardcowboy — Sat, 30 Jan 2021 04:59:52 GMT

How can I set a single interrupt handler for interrupts generated from 2 different ports?. I have interrupts enabled on pins PTD7, and PTE7 on MK64FN1M0VLQ12, but I want to execute the same ISR when either interrupt happens, and I know that both interrupts cannot happen at the same time (they happen one after the other). The component inspector in ProcessorExpert doesn't let me change the name of the Interrupt handler (see picture below)

I want to set both PORTD IRQ HANDLER and PORTE IRQ HANDLER to be the same (lets say updateCounter)

Hi @keyboardcowboy

PortD and PortE have different vectors , and they cannot assign the same ISR for the two interrupts. I have tried this with Codewarriror and KDS.

I would suggest you do the same thing in the PORTD IRQ HANDLER and PORTE IRQ HANDLER.
