Hi there,
I have problem reading ATMEGA16 ADC(setting: ADC interrupt with noise canceller/10bit). Actually this is not my first try with internal ADC,but this time with any reference, I receive data whith is not related to Analogue voltage.data is combination of 0x3F(satureated!!!) and 00. what could be the problem?
thanks,

Looks like initialization, reference voltage and reading data from ADC related issue.
Are you using AVR studio and any libraries ? if so check those functions used in initializing and reading of data. I am using ADC with AVR but did not experience such trouble.
Further information will help resolving the issue.
