We are doing a project of interfacing AD7730 with ATmega8.
we are able to successfully read or write in all internal registers of AD7730, but the problem is when we are reading data register we are getting '0', even though the input at analog pins was 5mV, and ADC is configured for 0-10mV.
we think that there is some configuration / calibration sequence is missing.. please help us in this regard...
Find attached code files for reference.
Any help is highly appreciated...!
