Subject: [DPRG] Processor Communication via ADC

I am trying to design the electronics for a bipedal walking robot, and
the software design includes 5 separate controllers in a hierarchy
such that each controller needs to feed a setpoint to the next tier of
controllers.  Would it be a bad idea to use a digital potentiometer to
generate an analog voltage that is the desired setpoint, so that it
can be read with the ADC of the next controller.  Normally I wouldn't
try this, but I need to get both of these parts working anyway for
other parts of the project.
