HELP! Reading two ADCs. Reading two potentiometer signals.

Hello everyone,

Right now I am working on a project with a DC motor and I need two potentiometers: one for sensing and one of reference (related to control systems) The thing is that I need to compare, maybe using if-else statements, the readings of two potentiometers whether one is bigger or lesser than the other. If anyone can help me on how to set this up in CCS it I will appreciate.

Thanks in advance,
LM

This thread has sample code to read the ADC and compare it to
the previous value. That's not exactly what you want, but it should help.

See this thread which shows how to expand that code so it
will read two ADC channels:
