Hello community

Would anyone please help me in using "SPLL_1ph" function using SDFM instead of ADC ? I want to measure the voltage of the grid with AMC1305 sensor.

Regards

    Lio, 

    The SPLL_1ph function does not care whether the input is coming from SDFM or ADC, the input of the module is a PU value of ACsine. 

    Please see the following example that uses ADC sensing for the grid voltage with SPLL. It is part of our C2000Ware-DigitalPower-SDK
