Part V - Converting OpenTX 2.1 Scripts

This section also covers some of the requirements for scripts that are necessary for them to function properly under both OpenTX 2.2.

New features

• LUA Widgets (Horus only)

• LUA Themes (Horus only)

Changes

• Lua Themes and Widgets run in a separate Lua environment. They are isolated from the other Lua environment which runs other scripts. This means they can not share variables, etc... (Horus only)

• Function scripts can have a background() function defined (similar to the Telemetry scripts). It will be called periodically when the switch that activates it is FALSE.
