I'm new to the VEX system. I've searched through the forums but I haven't found what I'm looking for. I'm programming the VEX kit using MPLAB. I'm trying to build a personal project using a VEX kit. I'd like the robot operate autonomously unless the RC is turned on. When it detects a good signal from the RC I'd like it to come out of autonomous mode so it can be controlled by the RC.

Is there any easy way to do this? I know that "txdata.user_cmd = 0x02;" enables autonomous mode and disables the RC.

I've noticed that VEX has a light to indicate when it has a good signal from the RC. Does anyone know how to detect a good RC signal in software?

Thanks for the help.
