Hi Team,
Good day. I'm posting this for our customer and they are using DRV8889A stepper motor driver.
Sleep pin is HIGH, DRVOFF pin is LOW and VM is 12V, They set the micro stepping to 1/256 using SPI and I have generated a PWM signal on the STEP pin but using an oscilloscope connected to AOUT and BOUT pins they can see that there is NO output to the coils of the motor, could you help us here (note that all other register values are left to defaults )
Thank you for your support.
Best regards,
Jonathan
