[Paparazzi-devel] Reply to:"Joystick control (Felix Ruess)"

[James Peverill]

We've actually been flying this way through the joystick/datalink for 
quite a while.  We have added a 4 channel message, and control the 
flight mode through button presses and the DL_SETTING message rather 
than through the position of one of the radio axes as is done with the PPM.

We've made a few improvements to the input2ivy actually:
  1. Moved the joystick xml configs to a conf/joystick directory.
  2. Added exponential to the axes.
  3. Added trim control for the axes (which as a side effect also 
allows you to control an axis up and down through button presses).
  4. Added support for joystick input devices (rather than just event 
devices).  I found that some joysticks don't really work well with the 
event interface (the ps3 controller being one) and floods the program 
with movements which caused some issues.

I think there were some other small fixes as well to the flight code and 
input2ivy as well.


This all has worked quite well for us.  We have the code in our fork at 
https://github.com/mantauav/paparazzi if you want to take a look.
