Some fixes to original script

Changes

• 1. It's working (there was incorrect call to the script at the end of debug.lua
• 2. It works on Radiomaster TX16S (should also work on Jumper and Horus) other radios make require some tweaks to supportedRadios list in CROSSFIRE/DEVADDR.lua

Some code was borrowed from ELSR setup script https://github.com/ExpressLRS/ExpressLRS

TBS Crossfire SmartAudio Script

Foreword: I'm not an OpenTX or experienced LUA programmer. Just sharing a homebrewed script.

This LUA script lets you change the output power of your a VTX which is connnected to a TBS Crossfire RX, based on a switch on your Radio.

The work is done through a MIXERS script, for easier setup a debug CROSSFIRE Lua Script is provided.

Requirements

• OpenTX 2.2/2.3x compiled with LUA support (like opentx-x9d+-noheli-lua-luac-en)
• TBS Crossfire TX Module - works with Micro TX or Full TX (firmware later then v2.92)
• latest OpenTX crossfire scripts i.e. https://drive.google.com/open?id=1YioQ2nS29a4gQlYbjqz66X7JjPSfVYnw (props: KamiKatzeFPV)

Installation

• 1. connect the smartaudio port of your VTX to CH1 or CH4 of the TBS Crossfire RX
• 2. set the output (of the wired channel) to "smartaudio" via the normal crossfire.lua or OLED screen
• 3. copy DEVADDR.lua and DEBUG.lua to your CROSSFIRE folder and execute DEBUG.lua

• 

• 

• 4. navigate to your "XF Nano RX", a section VTX should be visible
• 5. note the deviceID, address and value of the power setting

• 

• 6. place cfSA.lua into you SCRIPTS/MIXES folder
• 7. enable the script on the models "CUSTOM SCRIPTS" page in openTX

• 

• 8.1) set "LEVEL" to a globalvar of your choice

• 8.2) set "ADDR" to the address obtained in step #5

• 8.3) set "DEVICEID" to the deviceID obtained in step #5

• 8.4) optional, enable beep or sounds on script execution

• 

• 9. use SPECIAL FUNCTIONS to alter the GVAR and enter the powerlevel of choice
