The program main_stick in sw/ground_segment/joystick is not designed for the fixed wing airframes. I'm using it for booz airframes right now. But it is possible to adapt it to airplanes. The library usb_stick.h in sw/ground_segment/joystick is derived from Martin's work. He has already used joystick with a workaround in the flight plan and the file joystick.c you've compiled (that's why it is supposed to work only in auto2). Maybe he can explain how to use it.


address@hidden a écrit :

is there a chance to use a USB joystick at the groundstation as RC replacement 
via the telemetry link?

I experimented a bit with the XML configs, added joystick.c to the airframe configuration and started the main_stick program. main_stick recognizes the USB joystick and sends its positions (debug). How can I view/add this info to the messages window?

How does mapping of the USB joystick axis/buttons to the autopilot variables 
roll,pitch etc. work?

Can the USB joystick be used for ´normal` flight? I found only a if (MODE2 and flight plan block joystick active) statement in the code, changing it to if (1) didn`t help to move the rudders with the joystick...

Help please :-)
Best, Rainer
