Has anyone had any success writing their own control software for the Fun Rock, or reverse engineering the pinouts for the serial port? I'm now in a position to begin doing this myself, and I don't want to reinvent the wheel.

I just upgraded my PC from one that was running Windows XP, to a newer box with Vista. I had to use a USB to Serial adapter. The software runs, communicates with the wall, and initiates climbs, but once the program stats running, it just sticks with the initial condition, it doesn't track the changes in the program. Has anyone else seen this?

I've messed around with reverse engineering the serial port and was able to get it moving by duplicating/modifying commands sent by the control software. The problem is that the serial RS232 interface is extremely picky. I couldn't get it to work using several different RS232 converters. I was only able to send serial commands after bypassing the RS232 interface completely and hooking leads in directly to the chip (PIC16).

After messing with this for a while I've come to the conclusion that it would be easier to just remove the control board completely and replace it with a beaglebone for my uses. I will still use the motor control board but I want to make several modifications to the system itself that will be easier without being limited by using the serial interface.

I suspect that your problems with the new computer stem from using the USB - serial adaptor.

Message me offline if you want to talk about this more.
