Current version of FreeVario: 1.1.1

From the official Image 21033 of OpenVario, the FreeVario driver is integrated in the image. So you are no longer dependent on using images from FreeVario.de. If you have already installed an image higher the 21032, you can connect the FreeVario directly to your OpenVario without making any changes at the software.

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).
