Hi everyone! I'm have trouble with strange ADC single conversion offset.. I have RF04EB with cc2510. When I set ADC for single 8-bit conversion with 3.3V reference voltage, I get different values from those I have measured with voltmeter. Val. around 0V and 3.3V are matching, but in between I notice offset that is not linear, and it is the largest in the middle of scope ( about 100 mV ?!).
