The RC's PWM is not the same as the Stamp's PWM, so I'm guessing it isn't going to work. Furthermore, the stamp has no "PWM in" type function.

My main goal is to get an approximate value out of the Auxilliary Stamp Chip. Perhaps if one was truely desperate, they could use the tether/debug talk to the Stamp, but that's insane. However, that data I want to send is more "parallel" and I don't want to tie up tons of digital inputs.
Doing it throught the program port is actually not that insane. This is how RoboCon works, and it really isn't that hard. Plus, the Stamp has native support for RS-232, so you wouldn't even need any addition electronics. Unfortunately, it is not legal to exchange data in any way other than with the digital/analog inputs on the RC. This also rules out the idea of doing it with PWMs.

May I ask what advantage this would have, aside from letting you input a few number of sensors?
