Heading indication wouldn't work

[jlMarsu]

Hello

I built the vario on TT w/ 2.9'' paperink screen
I did setup Hardware config etc .. and compiled successfully
GPS / Display work fine.
Pressure sensor works fine (detects successfully pressure increase / decrease => vario speed)
I only have an issue with heading indication which either is totally random, or is about stand still.
I have ran the calibration process, including online calibration file computing, but don't get any improvement.

Maybe did I miss some setup in hardwareconfig file, but I can't figure out which parameter .....

Would you have any suggestion about what I could do to improve the situation ?

I am running at the moment the test code ....

Thanks for any feedback

Great project indeed!
