I'm new here and just picked up the mdd3a driver. I'm trying to understand the instructions at the beginning of the StepperFullDrive example, where it states: '// Connect 4 pin on SHIELD-2AMOTOR to "Signed Magnitude" mode'. I assume it's talking about setting up the 4 output pins to connect the driver, but it's clearly more than that. I see no jumpers or pin labeled as such. This is one of the examples in the Cytron 3A Motor Driver Shield library I got from Arduino, so maybe it's not even the right library...
Not wanting to fry this driver, I was hoping someone might explain it to me? I'm using an Arduino Nano to run a NEMA 17 stepper with this driver. Thanks in advance.
