The companion can be downloaded here. It's a very nice application that can, among other things, simulate a Taranis radio.
A very nice feature is to analyze logs from your quad. To do that, you first need to enable logs in your Taranis:
I have developed a script to extract GPS coordinates from the CSV log file to a GPX file. You can download it from here: https://github.com/sebastiendamaye/public/tree/master/csv2gpx.
The below procedure explains how to flash OpenTX on a Taranis X9D+.
- Go to http://www.open-tx.org/ and check the last version available in the section:
- Now, download the latest available version from the section:
- You'll need these 2 files
- SDCard content
- OpenTX Companion
- Put the Taranis in bootloader mode (press both horizontal trims inwards while powering on the radio):
- Once done, plug the USB cable.
- Open CompanionTX and go to menu > :
- Save as
- Go to > and customize the screen as follows:
- Select > . In the window, select and click on .
- Now, select > .
- Once finished, uncompress the content of the SDCard Content previously downloaded from OpenTX and replace the content on the memory card in your radio with the one just uncompressed.
- Properly eject the Taranis, unplug the USB cable and restart your radio to check that it works fine.
Flash the bootloader
To flash the bootloader:
- Copy the *.bin file to the FIRMWARE directory of the SDCard
- Rename the file so that it only contains 8 characters (e.g. OPENTX223.bin)
- Eject the Taranis from the computer and select EXIT from the bootloader menu
- Navigate to the files page of the Taranis and go to the FIRMWARE directory
- Hold on ENTER and select Flash bootLoader
From the main screen, long press thebutton to access the main menu.
This screen lets you update, among other things:
- alarms (e.g. low voltage battery on radio)
- regional settings (country, language, ...)
- radio mode (i.e. mode 1, mode 2, ...)
View, delete files on SDCard.
This screen will be helpful if you want to setup a trainer mode, in case you are learning with an instructor (the instructor will also have a radio).
Show version of OpenTX.
This screen can be used to check that all switches/buttons/sticks work properly on your radio.
This screeen shows the current value of your AUX channels. For example, the throttle stick associated toon the below screenshot has value (minimum: -100, max: +100)
This screen will let you calibrate the sticks and pots on your radio. It is an important process that should be done at least for the first use, as well as if your drone drifts.
From the main screen, long press the telemetry setup.button to access the telemetry screen. It will display the telemetry screens (see below) defined in the
Views (short press PAGE)
Once on the model screen, short pressto switch between these views:
This screen enables you to select a model, back it up, copy it, ...
This menu will let you:
- label your model
- choose an image
- create timers
- create switch positions checks
- define your radio receiver and bind it. See how to bind the FrSky X4RSB radio receiver
- define the failsafe behavior. See how to configure failsafe on your radio
- define the trainer port (e.g. Slave/Jack to connect to PC)
This screen will let you define flight modes as well as the associated switch. It is very common to define the following flight modes:
- Angle (SD switch in the upper position)
- Horizon (SD switch in the middle position)
- Accro/Rate (SD switch in the bottom position)
This screen will let you define the inputs. You can consider the inputs as custom labels for the radio commands (sticks, buttons, ...).
To modify an entry, long presson the selection. Most of the time, only these 2 fields will need to be updated:
To modify an entry, long presson the selection:
This screen will be usefull to fix the minimum and maximum values read by the flight controller software (normally 1000-2000 range, with the middle set to 1500).
This screen is where you define logical conditions. What you do is that you create conditions and you name them in order to refer to them in the next screen (special functions).
It is very convenient to get the value of the lowest cell of your lipo from the telemetry, and raise an alert if this value gets below a certain limit.
Special functions make use of physical switches or logical switches to trigger actions (play track, play sound, ...).
It is very convenient that your Taranis is talking to you when you are wearing FPV goggles :)
Notice that not all receivers are able to provide telemetry information. If you're interested in this feature, ensure that your receiver supports it before bying one. The FrSky X4RSB radio receiver is very popular in FPV racing/freestyle because it supports it natively, is lightweight, has a good radio range and is affordable.
First click on:
Then identify the sensors you are interested in (e.g.is the power sent by the VBAT link and is the lowest cell voltage):
Then add widgets to your telemetry wall:
Here is what it looks on the telemetry screen:
