Hi,

I have a problem with AFE and ADC module. I need to read neutral and phase voltage &current values from the device. I didn't understand how to do initializations. I need proper meteringlib header files. mkm34z256vll7 microcontroller 39 and 40 pins doesn't have portnum and pin num . how to use that pins. how to select channel for AFE.I have gone through data sheet https://www.nxp.com/docs/en/data-sheet/KM34P144M75SF0.pdf here I couldn't get information about pins. I'm using IAR EW.

Hi @Divyasree ,

Please download KM34 SDK package from https://mcuxpresso.nxp.com/en/welcome. There is AFE and ADC examples in the package.
