I am trying to use Vref on the 12F675. I only require A0, as an analogue input, but I need to use A1 as the reference. How is this accomplished using the 12F675?
I am having a ferw problems getting the 10-Bit ADC value out of the 12F675. All I want to do is turn two LED's oon depending on the input voltage. The voltage can go between 0-Vdd, and I want 0-1023 ...
