Hi
Im using 3 DRV8825 modules to move my 12.5" telescope with worm gears, in that behavior a holding torque is not necessary at all and is just a waste of energy from the batteries. So I just DISABLE and ENABLE the driver every time I need it to use it, but that need a digital pin from the STM32 Bluepill MCU to manage each motor for the ENABLE signal.
There is any way to configure the DRV8825 to maintain 0 holding current without the use of the ENABLE pin when no pulse is send to it?
I think on connecting the STEP pin to the SLEEP pin…
