Hi all

I've been using X-Plane to develop navigation/takeoff and landing for a .60 trainer. X-Plane exports (in real time) all sensor data via UDP and accepts control surface deflections input (as well as throttle) with UDP inputs.

By the way, since it uses UDP it frees you to choose whatever programming language you like to write the prototype code.

It also outputs pitch, roll, yaw settings (real heading + mag heading + ias + tas) so you can use whichever values correspond to the sensors you will have on board.

It's great to prototype. It took me 2 days to develop a full PID autopilot with X-Plane. Now i just have to scale UDP deflection values to servo values and copy the code to the mcu.

Cheers

Filipe

Fixed (version 1.16 of sw/tools/gen_flight_plan.ml)

Thanks for you exhaustive tests !

When someone gets a chance, could they try a mission in Paparazzi2 with
an xyz,
a simulation that is.  When I run it the desired_pitch increases, and
continues
to increase without bound. I want to know if its Isolated to me or if
everyone
has the problem with the new pitch code in the 1.54 update, thanks

Hi Anton,

Pascal,
found a nasty bug in the code today. If you use vmode="gaz" and give
a gaz
setting gaz="?" you are unable to also specify a pitch angle.  This
may be a
bug from adding autopitch I am unsure.  Good luck




  You are right.
Before the auto_pitch mode was added, "desired_pitch" was computed in
navigation_task() (main.c) with
    desired_pitch = nav_pitch + pitch_of_vz;
and it was independent from the current vertical mode.

This line has been unfortunately moved into climb_pid_run() (pid.c)
which is
called only with a vertical_mode greater than AUTO_CLIMB (i.e. CLIMB
or ALT).

  This is now fixed:
   - climb_pid_run() computes (if auto_pitch) or updates (else)
nav_pitch ;
   - desired_pitch is always set to nav_pitch in navigation_task()

Please check the source code before flying ...

 Hi,

What do you sink about the integration of a GPL flight-model in paparazzi such as Flight Gear
It can be a good to test virtually pid and other...

it's a C++ open source flightmodel projet (seems to "near" from with flight gear)

it uses xml configuration files ;-)
