Re: [Paparazzi-devel] spectrum

Hi Adam

The code to decode the spektrum radio control protocol is in
sw/airborne/booz/radio_control/booz_radio_control_spektrum.[ch] and a
makefile showing how to use it in
conf/autopilot/subsystems/booz2_radio_control_spektrum.makefile
The signal is an asynchronous serial signal and is available on the
connector of the spektrum satellite receiver, you don't need to
perform any surgery. The receiver is supplied by 3.3V

Regards

Poine
