RE: [Paparazzi-devel] Antenna Tracker

[mark.griffin]

Hi guys,
Just to let you know about the development of the antenna tracker code.

In October last year, I modified the \sw\ground_segment\cockpit\ant_track.c 
code to work properly over the IVY bus. That is the version currently in the 
repo.

Todd Sandercock then modified it to work with his Pololu controller. This is 
the version in \sw\in_progress\antenna_track\ant_track_Pololu.c. He had 
problems with his Pololu controller and the code doesn't work with a standard 
Pololu controller.

Chris has significantly improved Todd's code to work properly with a Pololu 
controller. It should be available shortly in the repo in the 
\sw\in_progress\antenna_track\ folder.

Cheers, Mark

Gareth,

did you try both? I seems on first glance there are some improvements
in the in_progress version...
