> i think i can help you .i implemented a project using ad7715 (similar
to ad7730) at first you should use a cristal for your avr " don't use
internal oscillator "
2-use very good refrance voltage
3-you should calibrate ad7715 then you can read from it
4-this function i have written can help you :(for ad7715)
