Grand Central M4 Express Interrupt Pins

Post by richbai90 »

I can’t seem to find any documentation on which pins on the Grand Central can be configured as interior pins. I’m using the Arduino platform.

If you go down to the SAMD51 level, you can have 16 of the GPIO lines be interrupt lines. See section 23 on page 409 the datasheet https://ww1.microchip.com/downloads/aem ... 01507G.pdf.

For use in the Arduino framework, have a look at https://forum.arduino.cc/t/samd51-inter ... ess/613980.
