True that it would require at least seven conductors to transfer 6 PWM signals, but that is only true if they are sent discretely. If they are sent via serial, it is quite possible that they could be sent over a four conductor cable.
After reading this thread last night, I decided to look into the default code for VEX. Now understand, I am
NOT a programming guru (yet), but I can figure a few things out by examination. It does look as though the signals sent from the Radio Controller to the micro controller are in fact PWMs. There appears to be no signals being returned to the Radio like there are on the FRC OI for things like LED's and Hex display.
BTW, I just ordered the programming kit yesterday
, it should be in this week, I hope, or early next week. I am also hoping the kit includes more info, like the other kits do. I'll post up what I received once it comes in.
