hi
you can certainly do it so easy. connect the analog inputs to two different channels of PORTA . select the channel you want to sample, wait for a delay of about 25 us and then take a sample.

note that you can switch between channels from the ADMUX register. after you switch the channel, you need to wait a delay of about convertion time simply 25 us to assure that changes will take place.

Hi
please refer to the atmega16 datasheet for detail. u can read from 2 channel very easily but at first u should specify your sampling rate then manage 2 different ADC channel.
