F28379D DRV8301 current sense problem

Hello,

I´m working on a U/f-Controll for Launchpad F28379D and DRV8301 to test current measurement.

I removed JP1 JP2 JP3 and set JP6. With DRV onboard AD-conversion is working and also host communication.

In the main ISR EN_GATE is set to high. The U/f control works fine and the motor spins.

On the Pins at J3 (IA-FB, IB-FB, IC-FB) I can mesure 1.65 V without an AC-component and therefore the serial monitor receives 2048 from current measurement.

Everything but the current sense is working.

My supspicion is that the gain for current shunt amplifiers is unselected.

I want to send over SPI, but is this the correct way?

constant block (hex2dec('16 bit word`) -> convert(uint16) -> SPI Master Transfer TX
