Special Features of Color Remote Controller Model Settings

I. Special Functions

The Special Functions section of model settings, as the name implies, is where you can configure the special functions included in EdgeTX. These special functions add additional capabilities beyond normal model control, such as enabling trainer mode, playing sounds, adjusting radio backlight, adjusting radio volume, etc.
On the special functions screen, you will see all configured special functions along with some configuration options such as function name, activation switch, whether the function is enabled, and other configuration options.

Selecting the + button will allow you to select an unused special function to configure, and the special function configuration window will appear. For information on configuring a new special function, see Configuring Special Functions below.
Selecting a configured special function will give you the following options:

• Edit - Opens the special function configuration page
• Copy - Copies the selected special function
• Paste - Pastes the copied special function to the selected special function. Note: This will overwrite the values of the selected special function with the copied special function.
• Insert - Inserts a blank special function above the selected special function
• Clear - Clears all configuration options for the selected special function.
• Delete - Deletes the selected special function.
• Enable - Enables the special function
• Disable - Disables the special function

1.1 Configuring Special Functions

All special functions have the following configuration options. Depending on the selected function, additional options may be added.

• Trigger - The switch that activates the special function.
• Function - The function to be used. See the function descriptions below.
• Enable - Toggle on/off to enable the function. To be able to activate the special function via a switch, it must be enabled. A disabled special function will not work regardless of the configured switch position.

    Set Failsafe - When activated, sets the custom failsafe value for the selected module (internal/external) to the current stick position. For this option to work, the failsafe mode of the RF module must be set to Custom.
    Play Sound - Plays the sound selected in the value field when activated.
• Value - The sound to play. Possible values are Beep1/2/3, Warn1/2, Cheep, Ratata, Tick, Siren, Ring, SciFi, Robot, Chirp, Tada, Crickt, AlmClk. Note: SD card sound pack is not required.

  Play Track - Plays the selected .wav sound file from the value field when activated.

• Repeat - The frequency to repeat the announcement. Options are !1x (don't announce at startup even if switch is activated), 1x (announce once), 1s to 60s (announce every xx seconds).
  Lua Script - Executes the Lua script defined in the value field. The Lua script must be in the /SCRIPTS/FUNCTIONS/ folder on the SD card. Lua scripts that display screen information cannot be executed with this special function.
• Value - The LUA script file to play from the SD card.
• Repeat - The frequency to repeat the Lua script. Options are: ON (repeat infinitely as long as the switch is activated) or 1x (once)
  Background Music - Loops the selected .wav file in the value field when enabled. The file should be in the SOUNDS/(language)/ folder on the SD card.

  SD Log - Creates a log .csv file of radio and telemetry values in the LOGS folder on the SD card. The radio will create new entries in the log file at the frequency configured in the Interval setting, with value options from 0.1s to 25.5s.
  Each time the function is activated, the radio will create a new log file, provided the function is activated for at least as long as the value setting. Note: If the available space on the SD card is less than 50mb, logging will not start.
  Backlight - Adjusts the brightness of the radio screen based on the source defined in the value dropdown. The brightness is limited to the on/off values configured in Radio Settings -> Backlight Screen.
  Screenshot - Creates a screenshot in .bmp file format in the SCREENSHOT folder on the SD card.

  Set Main Screen - Changes the currently visible screen to the defined screen number.
• Value - The screen number defined in the screen settings.
• Repeat - When the switch remains activated, the repeat value determines how often the special function will change the screen to the defined screen. Options are !1x (don't change at startup even if switch is activated), 1x (change once), 1s to 60s (change every xx seconds).
  This is useful because when the switch is activated, the user can still manually switch screens, and it will change back to the defined screen after the defined duration.
  Audio Amplifier Off - Disables the audio amplifier so the speaker makes no sound, including annoying feedback or interference. This option is only available on certain radios.
