reading electrical parameters by atm90e26 and pic18f

Hi guys,

I have single phase rectifier project. I need to read electrical parameters (volt, amp, watt etc.) on single phase AC.
I expect;
to read all parameters that atm90e26 can do it by PIC18F57Q84, then using zcd function on atm90e26 to trig thyristor.

design circuit on isis proteus and simulate,
programming on mplab x ide,
codes should be simple and understandable, and need description for codes,

thank you
