I am new to Frodo and car pc world. After installing Frodo an looking at the video input from my camera, I was wondering if you could make it automatically run a script in Frodo when a pin was grounded in the parallel port (like a backup camera when in reverse). I have found pinouts and scripts to use the ports link.
Also If you used a button on the frontend to control an output pin it could turn on fog lights, wipers, many other things. Please tell me if I think too much and do not need to pursue this any more.

thanks
