Error in code light on, trouble finding error
Hey guys, finally got code to compile (I really hate MPLAB now), and got it to download to the controller, but the OI has the code error, no valid data/radio (blinking red), Program state (blinking orange), and radio modem (blinking red) lights on, and the RC mode light is off. I've been looking through the code, and have no idea whats going on.
