Hi Team,
I am currently trying to drive the DRV8311 Eval board with a DRV8311P on it with an external MCU (not the launch pad).
The tSPI drivers are read correctly, and can be written also. However, no matter what the registers A-C is written after power up, as PWMG_PERIOD is 0x03e8 and PWM_EN is 1h, others register are default value, the OUTA, OUTB, OUTC is low. The VM power supply with 5V or 12V (configurable), OUTx is always low.
Is there a standard operating procedure or diagram for what registers need to be configured before successfully driving a motor?
Could you help check this case? Thanks.
Best Regards,
Cherry
