SmoothStepper USB / Using port 3 as generic IO

« on: August 01, 2012, 09:11:13 AM »

I want to use pins 1A, 1B and 1I (1, 2 and 3) as generic TTL inputs. How are these ports setup? High? Low? Do they have a corresponding pull up/down resistor? The lack of proper documentation can be frustrating at times.

Thanks!
