This project allows using an AVR-based Arduino with a USB-Host-Shield to be connected to a Saitek X52 (Pro) flight control joystick, generating a CPPM-Signal that can be fed to most common RC transmitters.
Features
All Parameters, like the channel count, CPPM specifications, endpoints, trim and invert, can be changed using the Multi-Function-Display on the Saitek Joystick and stored to the Arduino EEPROM.
A modified host telemetry port (D-Port) of an FrSky TX module can be connected to the hardware serial port so the link quality and voltage will be displayed on the Multi-Function-Display. Obviously, you have to remove the RS232 level-converter from the TX module or use an adaptor to bring the UART to 5V level.
Currently the code only supports the Saitek X52 series, but you could easily adapt the code to work with other joysticks or gamepads.
