Where to set ADC_REFERENCE_VOLTAGE?

[DMeie.2]

Our project uses an external ADC reference voltage of 3.03V.
This value is properly set up inside the json I use to generate the inital project code ("amplifyingNetworkVm": 3.03, "polarizationOffset": 1.515).

Now I found in the generated code that inside paramters_converison.h, the ADC_REFERENCE_VOLTAGE is set to 3.3V.

Where am I supposed to set up the correct value so that it gets used by the code generator and stays when regenerating the project in CubeMX? Can I just manually set it?

Hello DMeie.2,

Currently ADC reference voltage is fixed to 3.3V regardless the settings in your board description. The quickest work around to avoid ADC_REFERENCE_VOLTAGE modification after each cubeMX generation is :

- open the *.ioc file in your project directory with your favorite text editor.

- search MotorControl.ADC_REFERENCE_VOLTAGE and set to the desired value.

- save your *.ioc file

- reload your *.ioc file with cubeMX and generate your project

ADC_REFERENCE_VOLTAGE should be set to the correct value in parameters_conversion.h file.

Please note this work around works only if you regenerate your project with CubeMX. If you regenerate the project with STMCWorkbench, the *.ioc will be overwritten and your modification will be lost.
