Hello
I am trying to read two analogue values and I’m getting the same values for both. One channel is connected to a differential input instrumentation amplifier and the other directly to a humidity sensor. Independently the channels work. If I connect only one of the two the readings are fine. The program works fine when simulated with proteus. What might be the problem? Are there any special precautions that need to be made, what should happen to the unconnected channels?
I appreciate any help.
