I’m having trouble figuring out where I’m going wrong with the G2 motor driver. I’ve used these before and as far as I can tell, I’m using it the same as I did before. What I’m seeing is the drive current jumping rather than ramping with the PWM input.
Here are some more details of my setup:
Arduino PWM to G2 PWM (100 resistor between)
Arduino digital pin to G2 DIR (1k resistor between) pulled high
Arduino digital pin to G2 !SLP (1k resistor between) pulled high
I’ve scoped the PWM output and sure enough it ramps fine. I can set the PWM to 50% and that seems fine, but it won’t ramp up from there.
Am I missing something obvious?
