How does one test if an A4988 driver is working?
I installed a PSU Molex the wrong way around and fried an ATMega with 12V instead of 5V, and its possible that the four A4988 on the same board are toast as well. I’m hoping that since they weren’t driving the motors at the time, they might have survived, so would like to check them if possible.
I’m on OSX, so the Windows tool doesn’t help me, nor do I have an oscilloscope. Is there anything I could measure with a multimeter which could tell me what’s what?
Using them with a Gen7 1.2 RepRap board loaded with Teacup firmware and Pronsole & ReplicatorG on the computer.
