First am a newbie to FlightGear and am throughly enjoying the experience ;-)
Am hacking in pyqt experimenting/researching with sockets (to eventually
interface with Arudino)
The FG->output to pyqt listening is working great, with no major issues.
However I am having problems with the input side and would appreciate
some direction.
The issues are.
1) can I acknowledge/debug that fg is receiving the input from socket
2) unsure about the formatting of the <input><chunk>
3) unsure how to format the input variable in the correct way..
below are the various elements snipped in parts
my command line is
/home/flight-sim/flight-gear-9/source/src/Main/fgfs \
--fg-root=/home/flight-sim/flight-gear-9/data \
--httpd=9090 \
--aircraft=A380 \
--disable-real-weather-fetch --disable-clouds --timeofday=noon
--fog-disable \
--generic=socket,out,10,127.0.0.1,6789,udp,mash \
--generic=socket,in,5,127.0.0.1,6788,udp,mash \
--trace-write=/sim/gui/dialogs/autopilot/speed-active
and the mash.xml protocol file
<?xml version="1.0"?>
<PropertyList>
<generic>
<input>
<line_separator>newline</line_separator>
<var_separator>tab</var_separator>
<chunk>
<name>speed-active</name>
<type>bool</type>
<node>/sim/gui/dialogs/autopilot/speed-active</node>
</chunk>
</input>
<output>
<line_separator>newline</line_separator>
<var_separator>tab</var_separator>
<chunk>
<name>aileron</name>
<type>float</type>
<format>aileron=%03.2f</format>
<node>/controls/flight/aileron</node>
</chunk>
<chunk>
<name>elevator</name>
<type>float</type>
<format>elevator=%03.2f</format>
<node>/surface-positions/elevator-pos-norm</node>
</chunk>
---- snipped------
the python code
# eg "speed-active=true\n" is sent
datagram = "speed-active=%s\n" % (val)
print datagram
self.udpSocket.writeDatagram(datagram,
QtNetwork.QHostAddress(QtNetwork.QHostAddress.Broadcast), 6788)
help would be greatly appreciated
