Hello,
according to the datasheet the PIN is on D0 pin 46 because the PIC has a USB interface and not on B7
The Int1-4 are also not all correct on the listed PICs They actually have PPS pins and not fixed ones.
Dear Matrix Team please change quickly
Sincerely SpeedPIC
I have renamed the INT0 pin assignment now so it's now set to pin D0.
The other interrupts are remappable and can be configured via the interrupt properties. The simulated pin is locked to the first option as it currently cannot handle multiple options so let us know if you would like a different pin assigned for simulation purposes.
