sorry to trouble you to check my design.
Tthe design Drv8818 stepper motor driver designed by customer self is more larger than DRV8818EVM in vibration noise . so we would ask what the case will lead to this phenomenon?
In addition, how to set up the Decay mode according to different stepper moter and configure the RCA/RCB pin resistance and capacitance parameters?
The moter model number is 57BYGH7401 and Attachment schematic for reference, thanks .
