EdgeTX 2.4 Lua Reference Guide

NextIntroduction

The latest version of this guide will always be available . At the top of the left sidebar there is a version option if you are running an older version of EdgeTX or OpenTX and need the docs for that specific version.

This guide covers the development of user-written scripts for R/C transmitters running the EdgeTX 2.4 operating system with Lua support. Readers should be familiar with EdgeTX/OpenTX, the OpenTX Companion, and know how to transfer files the SD card in the transmitter.

Part I of the guide shows how to enable Lua support for Taranis and includes basic examples of each types of script.

Part II is a programming guide that introduces the types of EdgeTX Lua scripts and how to use them.

Part III is the EdgeTX Lua API Reference

Part IV addresses common issues in converting Lua scripts that were originally written for OpenTX 2.0

Part V addresses common issues in converting Lua scripts that were originally written for OpenTX 2.1

Part VI covers advanced topics with examples
