I am working on 3 phase energy meter using ADE7880...
For Energy measuring i use as below values
(200 Watt bulb)
LINECYC = 0x0258 ; // 600 cycles
LCYCMODE = 0x3F ;
1. How should i get the real word values ? ...Is that same llike(Vrms_const= Vrms/register value(xVRMS))
2. I use for wh/LSb= (V x I x 0.5 x 6 (sec for 600 cycles)) / (xWATTHR x 3600) ......is this correct?
3. when i reading the value from energy register , the value will sometimes increment and decrement....But as per meter reading it should be incremented on every time period....
4. In code , if i am not use interrupt like IRQ0 and IRQ1 then what will happen?....is this affect on application or not.?
Please , give valuable inputs on above questions
