MC Workbench change mcu analog voltage reference

I am working working with a PMSM FOC project in MC Workbench 6.2.1 and I am wondering if there is a way to change the mcu's analog vref input voltage. From the numbers I'm seeing on the current measurement page, it seems like MC Workbench is expecting the mcu to have a 3.3v reference on the vref input pin of the mcu. However, I don't see a way to change that in MC Workbench or a field for it in any of the board files for the control or power boards. The custom board I am using has a 3.0v input to the vref+ pin on the mcu. Is it possible to input this information anywhere?

Hello @captat ,

The field you are looking for is called "amplifyingNetworkVm": 3.3, and is present in the CurrentSensing features of the json description of the power boards or inverter boards.

Be aware that it is something we did not have the chance to test.

Regards

Cedric
