Particular Features in EdgeTX are one of many highly effective options that many FPV pilots overlook. Whereas Inputs, Mixes, and Outputs tabs deal with your fundamental stick and change mapping, Particular Features allow you to assign particular actions to switches or situations (like logical switches) — you are able to do issues like throttle minimize, voice readouts/alerts, quantity management, knowledge logging, and extra. On this tutorial, I’ll clarify what Particular Features are, offer you an introduction on how you can set them up, and present you some helpful examples.
What Are Particular Features in EdgeTX?
Particular Features are actions that occur when a change is activated, or a sure situation is met.
- Set off: Often a bodily change (SA, SB, SC, SH, and many others.) or a Logical Change.
- Motion: Play a sound, override a channel, change quantity, begin logging, and many others.
To entry Particular Features:
- Press the MDL button to enter Mannequin Setup.
- Hold urgent the Web page button till you attain the Particular Features tab.
Notice that Particular capabilities solely apply to the present mannequin (set inside every mannequin profile).
There’s additionally International Features that work the identical approach, however apply to all fashions on the radio. To entry International Features:
- Press the SYS button to enter Radio Settings.
- Press the Web page button just a few occasions to the International Features tab.
I normally put issues like quantity management and backlight management in International Features, so that you don’t must duplicate them in each mannequin. For mannequin particular capabilities I’ll use Particular Features.
How you can Add a Particular Operate
- Scroll to an empty line and press Enter.
- Choose a change in your radio.
- Select the Operate (what you need it to do).
- Set any extra parameters (worth, repeat, and many others.).
- Vital: Tick the Allow checkbox on the backside — many individuals overlook this and surprise why nothing occurs.
- Exit and check.
The road will normally spotlight or present an icon when the perform is energetic (e.g. whenever you activate the change, or situation is met).
Helpful Particular Features for FPV Drone Pilots
Play Worth
Press a button and your radio speaks the present battery voltage — tremendous helpful for fast checks earlier than flight or throughout lengthy classes.
- Change: SH↓ (Momentary change down)
- Operate: Play Val
- Worth: RxBt
- Repeat: ! (exclamation mark = play as soon as)
- Allow: Checked
I really wrote about this in a separate submit, even goes into element how one can flip this right into a low voltage alarm utilizing logical change, test it out: https://oscarliang.com/edgetx-voltage-callout/
You too can play different values like:
- telemetry values similar to RSSI, altitude, pace and many others
- stick positions
- knob positions
- sensor values
Play Sound Observe
As an alternative of taking part in worth, you’ll be able to play a sound monitor – an audio file (in WAV format) you set within the SD card.
It may be a voice announcement that claims “Ship It” whenever you arm the quad:
- Change: Your arm change (e.g. SD↓ for armed)
- Operate: Play Observe
- Worth: Select “armed.wav” (or no matter sound file you wish to use)
- Repeat: – (sprint = play as soon as when change adjustments)
Or voice prompts for flight modes, like “Angle mode”, “Acro mode”, and “Rescue Mode” and many others, as you activate them.
For instance, create a Play Observe perform for every change place:
- SC up → play “Acro mode”
- SC center → play “Angle mode”
- SC down → play “Horizon mode”
Or it may play music!
You’ll be able to create customized sound tracks following this tutorial: https://oscarliang.com/taranis-play-sound-track-mp3-files/
Quantity Adjustment
I’ve this arrange in all of my radios. It lets me alter the radio speaker quantity utilizing a knob or slider.
I normally assign Quantity to a potentiometer in International Features, so I can flip the radio quantity up or down at any time whatever the mannequin.
For instance:
- Change: ON (at all times on)
- Operate: Quantity
- Supply: S1 (or whichever knob/slider/rotary change you like)
- Allow: checked
Now, everytime you flip the S1 knob, the radio quantity adjustments.
That is a kind of options you don’t understand you want till you’ve gotten it.
Backlight Adjustment
This works similar to Quantity, however for display brightness. Most radios have two knobs, so it’s good, one for quantity and the opposite for display brightness.
Once more, I assign Backlight to a knob in International Features. It lets me flip the display brightness up when flying out of doors, or down indoor.
Instance:
- Set off: ON
- Operate: Backlight
- Supply: S1
- Allow: checked
Reset Timer
That is helpful if you wish to hold monitor of how lengthy you’ve been flying. Additionally very useful in case you depend on timers for battery administration and resolve when to land.
I usually use my Arm change to set off the timer, and once I disarm, it robotically resets it.
You begin the timer within the Mannequin Setup Web page below Timer 1 utilizing your arm change (arm place):
Then in Particular Operate you’ll be able to reset Timer 1 utilizing the arm change (disarm place).
You too can set a voice shout out each minute to remind your self how lengthy you’ve been flying.
Override Channel
You’ll be able to drive a channel to a set worth utilizing a change, it doesn’t matter what the sticks, inputs, or mixes are doing.
A standard use is Throttle Minimize, the place I usually use on my fastened wings that don’t have a flight controller. It acts like a arm change for security, by activating that change, it overrides the throttle channel, so irrespective of how I transfer the throttle stick, throttle worth is locked at zero so long as the arm change stays deactivated.
For instance:
- Set off: change SD down
- Operate: Override
- Channel: CH1 (or whichever channel is throttle)
- Worth: -100 (-100 is 0%, 0 is 50%, 100 is 100%)
- Allow field: checked
I even have a tutorial explaining in additional element: https://oscarliang.com/setup-arm-switch-for-wing-no-fc/
Information Logging
This allows logging to the SD card, helpful for reviewing flights later.
It may well document:
- telemetry values like GPS coordinates and battery voltage
- stick positions
- radio states
- and different helpful knowledge
Logs are saved to the SD card and could be analysed in instruments like Log Viewer.
A standard setup is to make SD logging begin when the quad is armed, instance:
- Change: Your arm change (or ON for at all times logging)
- Operate: SD Logs
- Worth: 1s or 0.5s (logging interval)
- Allow: checked
I’ve a tutorial explaining how you can set this as much as log and think about GPS knowledge: https://oscarliang.com/log-telemetry/
Screenshot
This takes a screenshot of the radio display and saves it to the SD card.
I make tutorials, so I discover it to be very useful. For odd pilots, perhaps it’s helpful for sharing your radio configurations on-line, or wish to hold a document of settings.
Professional Ideas
- Allow checkbox — Double-check this each time. It’s the #1 cause Particular Features don’t work.
- Order issues — Particular Features run from prime to backside. Conflicting capabilities could also be overridden by decrease traces.
- Voice information — Be sure that your sound pack is put in and information are within the appropriate folder (SOUNDS/en/ or your language).
- Use Logical Switches as set off — This unlocks superior behaviour (e.g., automated warnings based mostly on timer, telemetry knowledge, or different situations).
Closing Ideas
If you’re not utilizing Particular Features in your EdgeTX Radio, you might be lacking out! It turns your EdgeTX radio from a fundamental transmitter into a sensible, useful software. Particular Features in EdgeTX just isn’t probably the most complicated a part of the radio, however it’s definitely one of the crucial helpful. When you perceive the essential concept of set off + motion, the entire menu turns into a lot simpler to know and use.
