Part Number: DRV8301
Hi Team,
Customer used DRV8301 and he needed to modify OC_ADJ_SET via SPI. But SPI is always unable to communicate properly. It is normal to measure the SCK SDI data by the oscilloscope, but the SDO data is not normal. Regardless of which register of the DRV8301 is read, SDO only MSB is high. The yellow line is SCK as shown. Blue line is SDO. This is the waveform when register 2 is read. The register 2 value has been set to 0x0100 before reading.
Thanks.
