This section includes Acknowledgments and Getting Started.
The OpenTX team has no intention of making a profit from their work. OpenTX is free and open source and will remain free and open source. But OpenTX is more expensive to maintain than most open source projects. The reason is that there is a never ending flood of hardware to integrate and maintain code for. Hardware that costs.
Another reason is that OpenTX maintains a build server that serves firmware compiled on demand. This is where OpenTX Companion orders your customized firmware. The server is not for free and the bandwidth is ever increasing with tens of thousands of firmware downloads each month.
The OpenTX team is grateful to those who have donated to the project. You have helped making OpenTX and OpenTX Companion great.
The Github Donor List is updated at each OpenTX release.
If you would like to contribute to OpenTX, donations are welcome and appreciated:
OpenTX Companion 2.2 is available for download at http://www.open-tx.org/downloads.html
If you intend to use mixer scripts, when updating the firmware on your transmitter you need to make sure the lua option is checked in the settings for your radio profile (Main menu -> Settings ->Settings...) as shown below. This is not required if you only intend to run telemetry, one-time and function scripts, support for those is included by default.
Also note that the SD Structure path should contain a valid path to a copy of your transmitter's SD card contents, although that's not specific to Lua.
