Hi ADE experts,well, After following the kick-start steps to make the ade7880 works as an energy meter. I tried to read the Vrms and Vinsant registers but i found something weird. The register value always is high with little number of swing. According to the datasheet the ADC output swings between +5326737 and -5326738. when max input volt is .5v but the values doesn't follow that.
for debugging, I have read used the EVAL kit and the GUI to read the RMSvolt but also the value always high with little swing!. do i misunderstand something?
can you give some more information?
what are your input signals?
psm0 and psm1 pin voltages?
reset pin voltage ?
reference voltage ?
avdd and dvdd voltages.
Are you writing the run bit in…
Are you writing the run bit in the run register?
Take a picture of your setup.
Thanks Dave for your continuous support. it was a problem in the MAIN AC.thank you
