Function Scripts

Purpose

Function scripts are invoked via EdgeTX 'Lua Script' of Special Functions configuration page.

Typical uses of Function scripts are:

• specialized handling in response to switch position changes

• customized announcements

Execution & Lifetime

Function script is loded when model is selected. Script executes until

• it misbehaves (e.g. run-time error or low memory)

• One-time Script is running. When One-time script finishes execution, Wigdet Script resumes execution.

File Location

Function scripts are located on the SD card in the folder /SCRIPTS/FUNCTIONS/

Interface

Every Function script must include a return statement at the end, defining its interface to EdgeTX.

This statement returns a table with the following fields:

Parameters none

Return values none

Parameters none

Return Values none

Parameters none

Return Values none\

Example

local function my_init()
  -- Called once when the script is loaded
end

local function my_run()
  -- Called periodically while the Special Function switch is on
end

local function my_background()
  -- Called periodically while the Special Function switch is off
end

return { run = my_run, background = my_background, init = my_init }
