Tool/software: Code Composer Studio

Hello,

We are using a DRV8301 3 phase gate driver connecting to F28069M (LAUNCHXL-F28069M)

This is how i connect drv8301 to f28069

We use 28069 spi example , we just changed interrupt to sned data 0x800,0x8800 to drv8301

it can sand clocl and 0x8000 and 0x8800 to drv8301 but we can't get any data from drv8301 SDO PIN

1. how to enable f28069 CS pin by coding

2. shell we connect drv8301 SPO and f28069 SOMI or we can just use oscilloscope to get SPO data without connecting to f28069.

Hi,
Can you further elaborate on the pictures can you label which pin you care looking at with the oscilloscope? also by SPO do you mean SDO? can you still see the SCLK when you are having the data come out of the DRV8301?

Regards,
Michael
