Good day guys !!
I feel the need to obtain the information from my PixHawk in my Graupner MZ-24 screen. I found
some threads talking about a change in arducopter firmware to run the telemetry, not good at messing original controller firmware.
Then I found an "adapter" that staff of the AutoQuad made to convert the MavLink in Hott telemetry.
I come here to share a few changes I made in the project Mav2Rott downloaded here: http://autoquad.org/software-downloads/?did=31.
This is an adaptation to send the telemetry PixHawk for Graupner Hott Protocol.
Is correct with some features:
Battery Voltage;
Altitude for barometer;
Satellite count Speed;
Flight Modes Current drawn by the motor;
Direction of the Head;
I am not able to make it work:
Correct display Latitude and Longitude;
Distance of Home;
Direction of Home;
If anyone can help thank you very much.
The project is attached to the topic. The connections are equal to the jd-ioboard. I am using an Arduino Pro Mini.

and an idea from me,
can you add mavlink error massages ?
for ie not arm high gps hdop etc...
and a question,
which sensors must be emulated for minimum voltage amperage gps heading data?
Thanks for help
That is great work !!!!
Firmware latest must be download from old versions page. 1.4.1
Yes, this is good idea.
Some more rectification: why should we use sat count while we have GPS fix type?
This feature should be switchable via text menu like "YAW if spd less" (I'll think how to name it better)
If disarmed or no GPS fix, YAW should be shown always.
A symbol should be shown right to direction display "Y" indicating yaw, "G" indicating GPS travel direction.
More ideas are appreciated.
P.S. Could you make pictures of MC-32 RC screens I'd like to add to docs page.
I have GR-24 and it works ok with MX-16 and MX-20. Also MZ-24 with GR-16 was reported to work ok.

Your idea is a good approach, maybe a little extended:
If movement in air about <min> km/h and about <min> satellites show GPS direction else show compass yaw.
This will avoid changing direction on copters with weak GPS signal when hovering (there is always statistical movement without useful direction vector).

I have positive report with MZ-24. Which receiver do you use?
Please consult documentation here http://mediamax.pro/MAVLink2HoTT
You shouldn't tune anything in FC. All tuning is done via HoTT text menu.

May show compass yaw when on ground / disarmed and GPS travel direction in air.

Thank you, coordinates are now correct, perfect.
The flight-direction may need some more thoughts and discussion.
