Are you by any chance affiliated with MindSensors or FRC 540? If so, it would definitely be worth mentioning-- then your comments aren't being taken as being from some random person on the internet, but instead as someone who actually has knowledge of how this controller was designed, which is something many of the people in this thread are interested in, and lends your statements more weight.

If you are just some random person on the internet, ignore me, this back and forth is vaguely interesting (as someone who has very little knowledge of electrical engineering).
