+[This project](https://github.com/xythobuz/Saitek-X52-PPM) allows using an AVR-based Arduino with a USB-Host-Shield to be connected to a [Saitek X52](http://www.saitek.com/uk/prod/x52.html) ([Pro](http://www.saitek.com/uk/prod/x52pro.html)) 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.
