Arducopter MavLink To Hott Telemetry Adapter

Posted by marcelo siqueira lopes on March 22, 2015 at 4:04am 
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.

      Friend , I was dedicated to improve my Drone flight time just leaving it to the background , I was very interested in your code will test and see how it behaves .

      Here are HEX files.

      This code was tested on funduino pro mini controller with Graupner GR-12, GR16 and GR-20 receivers.

      RCs used in tested were Graupner MX-16 and MX-20.

      I'll appreciate feedback from owners of MC an MZ series RCs as I'm not able to test this confuguration.

    Thanks for sharing!

    I will try it as soon as my new AUAV-X2 arrives (small pixhawk comp. controller board).

    Good morning guys
    , 

    I'm sending firmware update to make the conversion MavLink ( Arducopter ) for Telemetry Hott . 

    It's working for now : 

    Altitude ( Baro ) 
    Speed ​​( GPS) 
    Latitude 
    Longitude 
    Battery Voltage 
    Battery current drain 
    Distance to Home
    Bearing to Home
    Satellite count 
    Flight Modes
    Direction of the Head;
