Need More COBRA II Digital IO


#1

I’m using CAN1, CAN2, COM2, and AD1-7 pins and still need a few more digital IO pins. Can I use the COM1, 3, and 4 pins or are there other COBRA pins that I can use for digital IO?


#2

All of the pins on the header are GPIO if you choose them to be. If COM 1, COM3, and COM4 are not being used as those peripherals, then they can be used without any problem as GPIO pins. The only thing to watch for is if you need an interrupt pin. Only Ports 0 and 2 are interrupt capable.
