Help Setting Current on DRV8825
« on: December 16, 2017, 01:55:25 PM »
I'm trying to set the Current limit on a DRV8825. I put the negative of my multimeter on the GND pin (top right when pot is in lower left orientation) and then put the positive probe on the VREF point. I see the full voltage of the attached battery.

But when I put the positive probe on the center of the potentiometer, I get 0 (zero) volts and turning the pot does nothing.

Please help. I've tried this on four drv8825 boards and all of them show 0 volts regardless of how I turn the pot.

Thanks for your help.

Gord
