[Paparazzi-devel] Re: Telemetry over UDP (Michael Weigand)

[Paul Cox]

Michael,

Poinix and others helped me last summer get telemetry and datalink working over udp (over wifi) with the fms code on the overo. It was on the "beth" test bench (which uses the Lisa-L board). My notes are on the wiki (http://paparazzi.enac.fr/wiki/Paul_Cox_Activity_Log#Summer_2010) and the code is in git (sw/airborne/firmwares/beth). I try to compile it regularly to make sure it doesn't break as the build system evolves, but please let me know if something is no longer working.

Paul

Hello All!

I was wondering if someone could help explain or give more detailed
instructions on how to get the fms code working on an OMAP3 computer
(such as an Overo or Beagleboard). I found the instructions below
after a great deal of googling but I can't figure out how to make the
code! ("make" outputs: "*** no rule to make target 'fms_main.c',
needed by 'fms'. stop.; and "make install" doesnt work either!)

Thank you for your advice!

Michael

1/ on the autopilot

  I have only used this on Linux based paparazzis, but I hear there's
some code floating around for sending UDP packets on LPCs who support
this peripheral ( not the 2148, though).
  On Linux, just compile sw/airborne/fms/fms_network.c and
sw/airborne/udp_transport.c
  There is an example ( overo_test_telemetry) with makefile in
conf/autopilot/lisa_test_progs.makefile and main in
sw/airborne/fms/overo_test_telemetry.c

2/ on ground

 start "link" with the -udp option. It will listen on port 4242 (
configurable with options -udp_port and -udp_uplink_port ). It
extracts paparazzi telemetry messages from the stream of UDP packets
it receives just like it does on a serial port
