The AVRRC program has been written in AVR Assembler, targeted at the ATMEGA8 microcontroller to provide a minimal-hardware cost efficient solution to interface Radio Control transmitters to Personal computers for diagnostic and application purposes.
AVRRC can emulate major interface protocols that allow it to be used with the FMS Flight simulation.
