步进电机驱动芯片: DRV8434S

如何从通过SPI接口从DRV8434S芯片中读取当前的微步序号?

How to read out the Microstepping Indexer from DRV8434S by SPI?

Annie Liu:

Sorry, DRV8434S doesn't support that function. When the winding current Itrip is zero, the bridge output could stop switching. I am not sure the host controller can detect it or not.
