Wow Menno, what a tremendous job. Makes me think of changing to GRP.

Cheers

Again very good job.
Thanks Menno.

Menno

Very nice work.

Graupner is not very popular in the USA. Do you know of other RC Transmitters could use your set up?

Taranis is what I have and it would be great not to have to use all the individual sensors with the AQ.

I believe the frsky taranis uses more or less the same half duplex technique for the protocol, so part of the code could be modified or used for the protocol.
The actual data conversion is obviously different. Peter has a taranis and already modified my mav2hott code to display some data, so I guess it should be possible to port it to AQ.
It is however time consuming

Excellent stuff, Menno.
The Graupner boyz will love it!

Waiting for confirmation or can we transfer it to the Wiki?

This is great work Menno!

One thing I will say is the GPS accuracy reported in cm is absolutely fantastic and makes PID tuning a lot easier. I never takeoff now until I get an error below 90cm or better. Such a great feature.

The distance to next waypoint is cool and really makes you appreciate the telemetry. I can't wait for the DIMU to be released so we can try the other great features that CAN brings.

I've purchased the breakout board that Menno designed for the external current sensor from oshpark, just waiting for it to arrive. At $1.20 delivered for 3 copies who can complain.

So many great features here and is one of the main reasons I purchased autoquad - absolutely fantastic work Menno!

Hi Menno,

impressive work! Well done!

Too bad that I'm one of those Spektrum users out there. Any chance to get native Spectrum telemetry from the AQ6 (we have a free-to-use I2C on board) or to have it bridged from your HOTT telemetry (on the external Mav2HoTT / LED / CAN board)?

I've collected some links dealing with Spektrum telemetry:

This guy is bridging Mavlink from an APM to Spektrum. Shouldn't be to complicated for you to add this functionality to the existing software running on your Mav2Hott Board.

Most of the reverse engineering info on Spektrum telemetry originates from this thread.

some of the (still missing sensor info) is here

Since the pro Mini/Micro's I2C interface is free to use on the Mav2Hott board the external solution could still be useful for all the spektrum guys (besides signaling only when Hott comes natively from the AQ6).

What do you think?
I will have the TM1000 telemetry with (at the moment) external GPS and capacity Sensor (bought one of those http://www.rctronix.de/wp/?p=163) on my CamCruiser and I could aid you in testing (and maybe coding) the telemetry stuff.

Ho Joerg,

Have to read all the stuff you posted, cannot comment yet on it My most used transmitter is a JR DXM-9 (spektrum) but from the pre-telemetry era so I don''t have HW that is usable. Have to see if it is straightforward to develop..
At least the interface is i2c and no slow bitbanging uart on the arduino.
