Trying to read current from the PDP

[franktate]

It does work now, mainly. Putting a load on the motor (with a finger) does get some different values returned. We just do still have some values coming from channels that aren't used. Oh well. This is just the test rig. Once we're on the robot, we'll be able to look at the data and throw out erroneous values (hopefully).

Thanks for your help.
