Other Parts Discussed in Thread: DRV8301, MOTORWARE
My hardware is DRV8301-69M-KIT, and I would like to modified OP gain of current sensing via SPI communication.
I try to read the register of drv8301 first, but I can't establish the communication.
I try to read "control register 1", and send a command, 0x9800, to drv8301. However, it do not have any response.
I have checked following:
SPI_VDD is 3.3V
EN_GATE is set to high, or low.
Swap SDO and SDI.
PVDD is 24V.
Change SPI clock from 1MHz to 10MHhz.
However, I still can't resolve. Has anyone can advise me?
The signal from top to button are CS, Clock, SDI(MCU to DRV), SDO(DRV to MCU)
