Hi all,
I just bought an FrSky Taranis for my quad copter and needed to get the Mavlink data up on the Taranis LCD telemetry display. So here is my solution using a Teensy3.1 as a converter between MavLink and the S.Port on FrSky X8R.
See attached file below...

Hi Jared
Placed an order on ebay last wednesday. Any idea on when you're planning to ship, because I have to plan for opening my Hexa to place the Teensy.

Dont worry ,it is on its way! :)
LoL
It's only the number of things that I have to take apart on my hexa that worries me :)
No, thank's ... it's very kind of you but i'm just happy to see that so many people likes the application.
Don't miss to change to the updated code ( Mavlink_FrSkySPort_1.3.zip) , there was a problem with GPS coordinates for the western part of the globe, this is now corrected.
okay, ill check it out, is there a charity you would like me to donate to maybe?
Rolf, IT WORKS!
The data was being passed. I finally saw how it was being reinitialized. Once I corrected that the data appeared in the Taranis as expected.
I did some playing around with sending data to the SPort when I couldn't get the live data working. What I noticed was that the ground speed displayed on the Tx was not a 1 for 1 representation of the data I sent. If I sent 25 the Tx showed 23, 50 ->49, 100->101, and 200->202. Have you seen this in your testing?
Thanks for your help in getting this working, and thanks again for making your code available so I could do this.

Roger,
Taranis is showing the Speed (FR_ID_SPEED) in knot and is using the following code for this:
frskyData.hub.gpsSpeed_bp = (frskyData.hub.gpsSpeed_bp * 46) / 25/1000;
46/25 = 1.84
This must be a fault in the taranis code. To convert m/s to knot the factor is 1m/s = 1.94384449 knot and not 1.84
In my code i have converted to km/h
