Tunigy 9x Firmware with Mavlink stack

Hello,

 

I release a new firmware for Turnigy 9x,

You can use telemetry from APM (watching battery voltage and GPS informations).

You can tune major value of PID (not all).

And the last you can change flight mod via Mavlink or PPM chanel. 

 

Actually I tested only on the last version of AduCopter, I thing you can easily change the sources code to adapt for ArduPlane

Main screen with alternate voltage display (transmitter and APM)

On the picture, '20.1' is the voltage of APM and 'STAB' is the flight mod

PID settings screen (can modify P & I parameters)

 

Settings flight mod cmd

 

I had two another parameters :

alarm on low battery from mavlink and the setting of the baud rate (it is preferable to get an high speed RF module)

Ya know, we should update my work to do the mavlink protocol. My ardupilot display was for old ascii data. I will be glad to help to change to mavlink, in fact I'd be delighted !

Ahhh! Yes! We should, great work Earl and I'm in the process of learning enough to help out. It's a lot of work and my load is huge but I'd like to find time to help get that going. Why don't you start a Group working on the 9x and such? It's easy to do that! Maybe we can all benefit.

ok sounds good, but remember I am going to school here in NM...UNM for astrophysicist so time is limited sometimes. Trying to keep my 4.16 GPA so far. A little hard at 65 yo. but I am gonna show them young wipper snappers !

Who says we don't have an uplink?  Couldn't we use the raw data encoded into a PPM channel to send data to the APM?  It would require "translation" code in the APM firmware to accomplish this, but I'm seeing the bigger picture... 

  • 9x with FrSky could be a standalone setup with PID tuning & save waypoint capability using your firmware.
  • Add bluetooth on the 9x, and then design smartphone GCS station.
  • USB connection (or bluetooth as above) from 9x (Smartieparts board?) to laptop in the field, for on the fly updates.
  • PC-based PPM encoder to FrSky directly.  You could then fly exclusively via joystick and not need a TX at all.  This capability exists already, just with the more expensive Xbee link.
