DRV8825EVM: Noise When Enabling DAC in DRV8825 Evaluation Module

Part Number: DRV8825EVM
Other Parts Discussed in Thread: DRV8825


I am using DRV8825 evaluation module , whenever i use DAC input for the VREF there is a lot of noise in stepper motor and the expected speed is not achieved.Tried slow and fast decay also no improvement.

Config:- 32 microstepping mode , fast decay enabled.

The same config with POT enabled in the module runs smoothly without any noise and distraction in the speed.
