Hi Roman,
Thanks for the reply. The bit I don't understand is that after I put in the
lines in the message.xml (code below), how will the GCS know when to use that
format and how would I have this data displayed on the screen?
--------------------------------------------------------------------------------
<message name="AirspeedData" ID="6">
<field name="airspeed_1" type="char" unit="m/s"></field>
<field name="airspeed_2" type="char" unit="m/s"></field>
</message>
--------------------------------------------------------------------------------
Another thing is that I can't find an 'autopilot' dir from inside the 'sw' dir,
and I had a look for downlink.h, although there are few files at various
locations, they still look reasonably same. I'm not sure which one to use?
Thanks
Kind Regards,
Brendan

Hey Brendan,
The whole paparazzi system is based on sending numbers through uart
from the autopilot, receiving them on the ground station again through
the uart. You may start looking at /conf/messages.xml and
/sw/autopilot/downlink.h.
The point is, you configure what messages you will have in your system
by specifying format for each in messages.xml, then write a wrapper
function for each and put them into downlink.h, and call them either
automatically at certain periods, or in the code whenever you need to
transfer something. This task requires knowledge of C though.
Sincerely,
Roman
