I want to use the eval board for ADE7878A with an external MCU by using the isolated pins.
I have tried to use the non isolated pins, it works correctly. But when I use the P17 port (isolated) I get wrong values (365072V instead of 230V). I closed the jumper JP21, soldered JP71, 72, 73, 74 for SPI use and reset the board MCU. Did I miss something ?
Thank you for your help.
