[Paparazzi-devel] joystick configuration problem

[Chris]

I think i need some help.
I am trying to use the joystick for flying a fixed wing without the 
standard rc using the datalink
but i am getting an error concerning the joystick.xml file.
Any help welcomed...

Here is the error from the GCS console output:

joystick ID (option -id): 129
Joystick SDL device index (option -d): 0
Fatal error: exception Failure("Couldn't parse message DL_SETTING")
Fatal error: exception Failure("Couldn't parse message JUMP_TO_BLOCK")

It used to work fine with the twog  but somehow with version 5.8.1and 
lisa_m_2.0  it isn't.
The joystick is detected just fine and it works if i remove the 
offending code
(ie the calls to "DL_SETTING" and "JUMP_TO_BLOCK"

here is the joystick file:
