DRV8305: SPI Communication

Zoey Wu

Part Number: DRV8305

Tool/software:

hi team,

my customer is using DRV8305 and the SCK and SDO signal is tested as below. the signal of SDI is always 0 and the VREG is 5v.

Could u kindly help to check what is the problem? thanks!

Hi Zoey,

Is it possible to get a waveform off all the SPI signals? SDO, SDI, SCLK, and nSCS?

Can they also provide a schematic?

Regards,

Yara

Hi Zoey,

From the SDI waveform it doesnt even looks like they are communicating with the device, are they sure their MCU is sending anything on SDI?

Regards,

Yara
