OpenTX – Application Note 01

Model Selection Text File and Audio Files

When the radio is turned on or the model is selected, display a check list text file and play an audio file.

 

This is an example of a text file.

 

 

Audio files at model selection time may contain music, reminder to do a range check, reminder to orientate the antenna appropriately, other pre-flight checks or anything else you can imagine.

Create The Text File

Using a text editor, like Notepad in Microsoft Windows, create a text file with name ‘Modelname.txt”. ‘Modelname must be exactly the same as the name of the model, without blanks.

The width of the Taranis screen is 35 characters so limit each line in the file to 35 characters. The screen has 7 lines below the heading but you can scroll down to more lines.

 

Information to include in the file.

   Switch operation, for example, flight modes, timer control

   Slider operation, for example, sound volume control.

   Pot operation,

  Telemetry data that is valid,

  Trainer setup,

  Pre-flight check list.

Transfer the Text File to the SD Card

The text file can be transferred to the SD card several ways.

 

USB Cable file Transfer

On the Taranis, display the Bootloader screen. Connect a USB cable between the PC and the Taranis. Use OpenTX Companion or Windows Explorer to transfer the file to the SD card folder [MODELS].

Refer to the ‘Power Up Screens’ section of the Control Flow page for information about the Bootloader screen.

 

SD Card Removal

Alternatively, with the Taranis power off, remove the SD card from the battery compartment of the radio and plug it into the PC. Transfer the text file to the SD card folder [MODELS]. Reinstall the SD card in the radio.

Enable the Checklist

On the Model Setup screen, highlight the checkbox next to the ‘Display Checklist’ Parameter under the Preflight Checks. Press ENT to tick the box.

Confirm The Text File Display Works

On power up, after the splash screen and warning screens, the text file is displayed. The text file is also displayed when a new model is selected.

The text file can also be displayed from the main screen by pressing ENT LP and selecting ‘View Notes’.

If there are more than seven lines in the text file, use the ‘-‘ and ‘+’ buttons to scroll down and up.

To exit the text file, press EXIT.

Create The Audio File

Refer to Application Note 4 for information on audio file creation.

A special function is used to play the audio file once when the model is selected.
