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...

My apologies if this has been covered but I have looked through the last forty or so pages and can't find any help.
My set up: Pixhawk AC 3.3 - FrSky FLVSS - OpenTX 2.1 on a X9E with latest firmware - Lastest Clooney 2.1 with lua, compiled and uploaded with no changes to includes or defines. Telemetry set up as per Wiki on 9E
Telemetry works as is should with lua script except for lowest cell voltage (Cmin) and distance/direction to home in lua screen. All other telemetry values are transmitted and respond perfectly. I have gone over, re-done and otherwise beat this to the end of my understanding for the last several days. Could really use some help on this one.
Thanks, RandyB
Looks like 3.3 is default and 3.2 is commented out so I left as is.
Randy, On your telemetry sensor setup screen on the Taranis, do you have the Cmin sensor setup correctly? - If it is configured correctly, then with your Rx powered, and FLVSS correctly connected to s-port, plus LiPo balance connector connected to FLVSS etc, you should see the value of the calculated Cmin sensor displaying and updating on this sensor setup screen. If this appears to be displaying OK then check your spelling of the Cmin sensor name on this screen, as this is case sensitive in the LUA script, so its important its named with an upper-case 'C' and lower-case 'min'. The LUA script basically accesses this sensor data by name and displays the value directly onto the telem1 screen. If this is set correctly, and still not displaying, then can you make sure you are using the lua script from the s-c-l-v-rc-opentx2.1 branch, and not the -next branch (as this determines minimum cell voltage in the code and not through the calculated Cmin telem sensor)?
I have done some testing on all these script revisions and I also do not have working distance from home, so you are not alone. Clooney is aware of this issue.
I only know enough about Arduino C to get myself in trouble but it seems to me that there needs to be a variable called 'Cell' to get single lowest cell voltage from the FLVSS and the 'Cels' to get the sum of all cells for battery voltage as we had in the original code. Otherwise using the Cels you could only get battery voltage divided by the number of cells and that is not worthwhile info. In the WIKI it shows 'Cell' as the source for 'Cmin' but does not give any setup for 'Cell'
Thanks Paul, I believe that I have everything set up right. I had it working with the original Rolf teensy code and open tx but not after the switch to 2.1. I have checked setup multiple times and still can't get Cmin to display on the sensor setup screen, all other values are live and working as expected. I am going to spend a little more time on it this evening. I'll post results. Am I right that nothing has to be changed in the sketch if the FLVSS is used? When I use Cels as the source I get battery voltage for Cmin.

I have APM 2.6 with 3.2.1 firmware and taranis with OpenTx 2.1.6.
I have download : https://github.com/Clooney82/MavLink_FrSkySPort/tree/s-c-l-v-rc-ope... and send to Teensy3.1.
In MavLink_FrSkySPort, change this:
#define AC_VERSION 3.2
//#define AC_VERSION 3.3
and
#define MAXCELLS 4 (4S Lipo)
Compile ok, but not work.
In old versión "MavLink_FrSkySPort_1.3" led flashing in Teensy. In new versión led is ON.
Please help me.
Hi,
I downloaded the led-control tree https://github.com/Clooney82/MavLink_FrSkySPort/tree/led-control .
I did everything as stated in the wiki using the Teensy version MavLink_FrSkySPort.
If i comment the two led lines for led it compiles, but if i copy any led-control file one folder up it does not compile anymore.
'get_gps_status' was not declared in this scope, if i shift the function over the function it gets called in this goes on with other functions.
Can anybody help me, how can i get this to compile?
Well i'm looking for some help with the sounds pack ....
In the github there is the 3.3 sounds and the normal sounds
which do i put and where??
I have this directory
https://github.com/Clooney82/MavLink_FrSkySPort/tree/s-c-l-v-rc-ope...
in this folder on the SD card SOUNDS/en/TELEM
i upgraded to 3.3 last night what do i need to do with the sounds now??
do i remove the files in this folder on my SD card ( SOUNDS/en/TELEM ) and replace them with the 3.3 sounds??
or do i keep the directory structure on github and create a new folder structure on the SD card
SOUNDS_AC3.3/en
Thank you
