Intro

Lua Version 5.2.4 from Fw 3.1.0 (https://www.lua.org/manual/5.2/)
3.1.0 only one script running in on own Thread in Safe Mode
From 3.2.0 FINAL file access available
multiple parallel Scripts run in one Thread in Safe Mode
Full LUA support
Execute any PFAL cmd -> avl.pfal("command")
Get Answer as String and Execution State
PFAL event call back -> avl.event(timeout)
PFAL state request -> avl.state(type[,index])

prerequisite Setup

use you preferred OS
install a bash and zip to compile a frp
- on Windows you can use WSL(https://docs.microsoft.com/en-us/windows/wsl/install-win10) or Cygwin (https://www.cygwin.com/)
- on Linux its build in or add via 'apt-get install bash unzip'
- on MacOSX its build in
setup your favorite IDE - preferred with build in LUA Highlight and/or COde check we can recommend :
IntelliJ (https://www.jetbrains.com/idea/) CE Edition is free of use
- download and Install IntelliJ
- start IntelliJ
- got to File/Settings/Plugins -> Browse repositories -> Type "LUA"
- select "Lua language integration for IntelliJ" click install
- checkout this repository File/new/Project from Version Controll/git
Eclipse (https://www.eclipse.org)
- Download Eclipse
- install Eclipse local
- go to HELP -> Eclipse Marketplace type "LUA"
- install "Lua Development Tools"
- go to HELP -> Eclipse Marketplace type "TM Terminal"
- install "TM Terminal 4.0"
- checkout this repository File/new/Project from Version Controll/git
there is NO need to have a local LUA Interpreter (https://www.lua.org) but you can use this for other projects as well
you need a FALCOM AVL EVAL Kit with at least FW 3.1.0 RC20 - FW 3.2 recommended

Sample Code

Sample is in the master branch of this project. so please checkout this project from here : git@git.falcom.de:pub/demo_lua.git The master branch will contain all snippets and demo script as well as a shell script to build OTA update package for FALCOM AVL.
