Change log

EdgeTX version
Change

2.4.0

Introduced

2.6.0

added filename to return value table.

2.8.0

added extendedLimits , jitterFilter, labels to return value table.

Examples

Displaying model's name

local modelInfo -- declare variable available to all functions 

local function my_init() {
    modelInfo = model.getInfo() -- read model's info table
}

local function my_run(event) {
    lcd.clear()
    lcd.drawText(0, 0, modelInfo.name) -- display model's name
    return 0
}

return { run = my_run, init = my_init }

Displaying model's all information

local modelInfo -- declare variable available to all functions 
local lineHeight = 8 -- for color radios change to 16

local function my_init() {
    modelInfo = model.getInfo() -- read model's info table
}

local function my_run(event) {
    lcd.clear()
    local y = 0
    for fieldName, fieldValue in pairs(modelInfo) do
        lcd.drawText( 0, y, fieldName .. ": " .. tostring(fieldValue) ) -- display model's name
        y = y + lineHeight
    end
    return 0
}

return { run = my_run, init = my_init }
Previousmodel.getGlobalVariable(index, flight_mode)Nextmodel.getInput(input, line)
