Hey,

Does anyone know if you could get data from an RC receiver through a phidget 8/8/8? I'm sort of thinking you could just use the digital input... and connect servo extention wires from the receiver to the digital inputs...If you connect a common ground, and then the signal wires? I don't have much in the way of experience with digital inputs.

Just thinking this would be a great way to control a robot...well...you get it.

Ok...first try didn't work. I'm thinking maybe I could use a servo in between and somehow get the signal from the potentiometer? Any ideas on where I would get the leads from?

Seriously has anyone tried to get an RC signal and feed it to a computer either through an SSC-32 or Phidget 8/8/8? Seams like this might be handy for mechwars.

The Phidget 8/8/8 isn't going to be fast enough to read the R/C signal and I think the SSC-32 may have a couple GPIO lines, but I'm not sure. You'll most likely need a microcontroller running a program like this one (http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1199165055) to decode the R/C signal.

Edit: The SSC-32 does provide four inputs, but they are not designed to measure pulses but rather slower events. Since the SSC-32 software is open source, you could modify it, but it's probably simplier just to through another microcontroller at the problem (one that supports something simple like a pulsein).

You need a microcontroller to read the R/C PWM pulses. The SSC-32 can be used for discrete digital I/O, but I have my doubts as to whether it will be fast enough due to being controlled via the serial port using ASCII text commands.

If you wrote new firmware for it. The SSC-32 is a "glorified Arduino" under the hood. Or maybe that's vice-versa.

I've been wondering about plugging an Atmega168 with the Arduino bootloader into an SSC-32 ever since I got my Arduino. The SSC-32 already has all those nice 3 pin headers. I'm going to have to look into the communication aspect and see if I can communicate with the bootloader on an SSC-32. That means I will probably have to look at the sources for the SSC-32 firmware also.

There are so many things I want to do.
