Circuit diagram for single phase energy meter with ADE7763, ACS712-20A, PIC18F?

Hi,

I am trying to do an single phase energy monitoring project. The voltage and current I want to measure is 240Vrms and 20A rms respectively.
I am planning to use a voltage divider for voltage measurement and ACS 712 -20A for current measurement . Micro controller planning using is pic 18f series. Energy meter Ic planning to use is ADE 7763.
But i have no idea about how to design circuit of energy meter( i am at level 0 at energy meter). So please provide me with circuit diagram of energy meter using the components and specifications given above.


thanks in advance....
