Facing an error when using MCSDK 6.4.1

[一hang]

Hello,

I encountered an error when using MCSDK 6.4.1 (Motor Control Software Development Kit 6.4.1) to configure the STM32G431VBT for using the three-resistor internal operational amplifier and performing external differential gain sampling. I would like to ask how to resolve this issue.

The following images show my configuration process：

Hello @一hang,

For the current MCSDK implementation, only ThreeShunt_RawCurrents_Differential_ExternalGain_FilteredADCInput is supported on the STM32G4 series.
The description of the current sensing feature is available here.
