How compatible is the Xiao to an Arduino e.g. Nano?

Somewhere in your program you define the interrupt pin: #define kDCC_INTERRUPT 2 // make sure it says 2 for your interrupt pin

There wasn’t that line anywhere in the program - I have added it, it doesn’t make any noticeable difference.

PORT->Group[g_APinDescription[7].ulPort].PINCFG[g_APinDescription[7].ulPin].bit.DRVSTR = 1;

I think I spotted that whilst hunting for answers.

Previously you tested the outputs unconnected to the load with success. Are the outputs also able to drive the load when tested that way ?

I tested the outputs connected to the leds.
