RE: [Paparazzi-devel] GCS Receiving

[Brendan Chen]

Sorry to be so stubborn about this, but somehow i can't open the messages 
executable anywhere? I tried the terminal, just won't open, I tried it while 
the simulation is running, still won't open. Could you please tell me how and 
whether that executable is to be opened and how?

Also do I need to make modification to the messages.ml file to display the data?

Thanks
Brendan

Displaying messages graphically on GCS is tricky and requires changing
.ml files. What you can do for now is display then numerically using
messages.ml. I believe is is compiled as messages. file located in
/sw/ground_segment/tmtc, or just do a search. parameters are in the
file and I think is is messages -c downlink. It will show you all
received messages as a list in the window.
