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...

hmm, it is odd as in my current sounds directory I have messages up to code 125.
this spreadsheet does seem to end at 98 - ready to track.
I always assumed codes come directly from ardupilot firmware - is it a wrong assumption? is it a teensy code alone that assigns a specific numerical code to a message?
There's a second spreadsheet that I couldn't attach that covers those codes.
And the sounds are most likely the ones I've created on a Mac using either AVA or ALLISON synthetic voice.
The codes are generated at the Teensy, where a translator function checks the text message sent by Ardupilot and maps that message to a code that is sent on the OpenTX telemetry link, because sending the entire text messages over the OpenTX telemetry link was not viable.
The parser is here:

OK, now I get it.
With new EKF changes I think most important part is to figure out what warning messages to include into this mechanism. 'compass variance' and 'velocity variance' are probably most important ones, 'bad ahrs' is not quite clear if it is important or not, then it is a bunch of EKF error scenarios that also probably need to be evaluated, as I do not think current script will say anything specific in a case of an EKF failsafe emergency landing...
Hi,
do anybodyknow how I can get additional telemetry values an the taranis? I need the "sonarrange" value.
Thanks for any hint!
I found this very useful to decode MAVLINK messages from Pixhawk. Thanks. My latest problem is while this was very effective in reading data how can I set parameters on the Pixhawk using MAVLINK. In other words the reverse process. I have spent considerable time on the web but MAVLINK documentation is a real mess with no examples on how to use the GCS Mavlink library. For example - there is a SET_PARAM command but how to use it ?
i have added this script to show the error messages, on latest clooneys82 Lua scripts
but now it says : syntax error ( but it was working fine ), any ideas what could be wrong?, thank you

After Configuring all the telemetry parameters , how should the other pages be configured . And the rest of the SD folders ..
Thank you
Have a look at the readme here: https://github.com/Clooney82/MavLink_FrSkySPort/tree/s-c-l-v-rc-ope...
yes i did ,
the three pictures explains just the new telemetry screen configuration , but how to configure the rest ?, there are many missing pieces of information , and my question is if i should copy everything of the configuration that is valid for 2.0.17 for the rest ( the other lua scripts, the mix,es, input, flight modes, logical sw , special functions , there is no orientation on how to configure that part ..
this branch is under development. also devs are on trail and error with 2.1. so this is why there is no clear set-up information at this state of development.
if you need stable telemetry on apm please use opentx 2.0.17 and the main s-c-l-v-rc branch. this will work stable with no eu x8r firmware. on eu firmware receivers you need currently the new branch. but this is on many parts untested and buggy. because devs are working on different things over the whole code base.
