Most of the barcode sensors I've come across do the threshold sensing for you and just output a digital value - no need to use the adc.


I agree. When I did barcode decoding, the sensor itself was already returning a digital value--I didn't have to use an ADC to do that. If he's make the barcode sensor then I guess that'd be an issue. And I again agree with you, he'd want to use the delta in the sensor intensity, not a fixed, absolute value.
