Current version of FreeVario: 1.1.4
Here you will find everything you need to build. All data is also published on GitHub: https://github.com/SashLi/FreeVarioGauge
In the GitHub, you can find the older files in particular, in case you need access to the old files again.
IMPORTANT – PTT and mute function
If you want to use the FreeVario’s mute function, you need to have at least the FreeVario image from 20295 installed on your OpenVario. In addition, at least firmware V.1.1.1 must be installed on the sound board as well as on the display board. If you are using the sound board with the 3-pin connector on the back, but without the diode D1, a small change has to be made here. Please write me about this by email (dirk@freevario.de).
new OpenVario-Image incl. XCSoar 7.24, the new menu and FreeVario driver for the classic OpenVario
All images newer than 22005 are optimized so that switching between STF and Vario mode works correctly when using the FreeVario together with the stick remote control. Of course, the images can still be used without FreeVario, but then other settings must be used to use the stick remote control. The exact procedure is described in the assembly instructions.
