Hi !

I ve interfaced ADE7758 with PIC18F4520 !  I'm getting trouble in reading the WATTHR, VAHR and VARHR registers !

 

i have connected a 10 watts resistive load to my board, I can able to read VRMS, IRMS and Frequency of all the three phases exactly without any error.  But when i m reading WATTHR registers, i m getting values around 65000d.  I dont know what is the problem.  I m using ADE config registers as follows

OPMODE - 0x04

MMODE - 0x00

WAVMODE - 0x00

COMPMODE - 0x00

LCYCMODE - 0x3F

 

LINECYC - 0x8000

 

Can anyone help me out to solve this issue !
