DRV8350: Cannot write data with SPI, but can read data normally

Annie Liu

Part Number: DRV8350

Hi Team,

The customer reads and writes data to DRV8350S through SPI, he found that the data cannot be written in, but the internal default value can be read. Would you help to share your suggestion for this case?

Thanks,

Annie

Hi Annie,

Has the customer reviewed our SPI FAQ? LINK

We often see customers unintentionally disabling the device through the ENABLE pin (which resets the SPI register settings).

Thanks,

Matt
