Please check if the ADC configuration is correct and the output is connected to the ADC channel you are using.

You might provide more information about this topic if you still have questions.

Which ControlCard? What current sensing you measured? The ADC registers configuration and reading code...

What example project are you using? The example project is in ControlSuite or motorWare? If not, provide more information about the ADC configuration.

You might take a look at the hardware guide of the DRV812kit, make sure that the switches are set correctly.
