I am new in forum please be forbearance. I tray to read Vrms using ADE7763+ATmega16A (SPI communications). I can read and write to ADE7763 register but when I plug voltage to channel 2 of ADE7763 register with VRMS (0x17) they show 0. Only after power up for ~2 seconds show fast changing number and then stop on zero. Where is the problem? Please see attached schema.
Best regards ,
