Hi to all engineers. I am working with 16c71 to learn more about it. this is what I know about it. 1. adres A/D result will be in this register after conversion 2. adcon1 to setup analog inputs and Voltage reference 3. adcon0 conversion clock, analog channel select, and more I played with one A/D converter I got good result. since I see only one result (adres) register I do not imagine using all four A/D converters where are you going to put results from each A/D converter at the same time. Could you please explain how it works. Andre Abelian.
