Particular Capabilities 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 Capabilities allow you to assign particular actions to switches or circumstances (like logical switches) — you are able to do issues like throttle lower, voice readouts/alerts, quantity management, information logging, and extra. On this tutorial, I’ll clarify what Particular Capabilities are, offer you an introduction on set them up, and present you some helpful examples.
What Are Particular Capabilities in EdgeTX?
Particular Capabilities are actions that occur when a change is activated, or a sure situation is met.
- Set off: Normally 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 Capabilities:
- Press the MDL button to enter Mannequin Setup.
- Maintain urgent the Web page button till you attain the Particular Capabilities tab.
Observe that Particular features solely apply to the present mannequin (set inside every mannequin profile).
There’s additionally World Capabilities that work the identical method, however apply to all fashions on the radio. To entry World Capabilities:
- Press the SYS button to enter Radio Settings.
- Press the Web page button just a few occasions to the World Capabilities tab.
I normally put issues like quantity management and backlight management in World Capabilities, so that you don’t must duplicate them in each mannequin. For mannequin particular features I’ll use Particular Capabilities.
Tips on how to Add a Particular Perform
- Scroll to an empty line and press Enter.
- Choose a change in your radio.
- Select the Perform (what you need it to do).
- Set any further parameters (worth, repeat, and many others.).
- Necessary: 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 lively (e.g. once you activate the change, or situation is met).
Helpful Particular Capabilities 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)
- Perform: Play Val
- Worth: RxBt
- Repeat: ! (exclamation mark = play as soon as)
- Allow: Checked
I truly wrote about this in a separate put up, 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/
It’s also possible to play different values like:
- telemetry values akin to RSSI, altitude, pace and many others
- stick positions
- knob positions
- sensor values
Play Sound Monitor
As an alternative of enjoying 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” once you arm the quad:
- Change: Your arm change (e.g. SD↓ for armed)
- Perform: Play Monitor
- 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 Monitor perform for every change place:
- SC up → play “Acro mode”
- SC center → play “Angle mode”
- SC down → play “Horizon mode”
Or it might play music!
You may 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 regulate the radio speaker quantity utilizing a knob or slider.
I normally assign Quantity to a potentiometer in World Capabilities, so I can flip the radio quantity up or down at any time whatever the mannequin.
For instance:
- Change: ON (all the time on)
- Perform: Quantity
- Supply: S1 (or whichever knob/slider/rotary change you favor)
- Allow: checked
Now, everytime you flip the S1 knob, the radio quantity adjustments.
That is a type of options you don’t notice you want till you may have it.
Backlight Adjustment
This works identical to Quantity, however for display screen brightness. Most radios have two knobs, so it’s excellent, one for quantity and the opposite for display screen brightness.
Once more, I assign Backlight to a knob in World Capabilities. It lets me flip the display screen brightness up when flying outside, or down indoor.
Instance:
- Set off: ON
- Perform: Backlight
- Supply: S1
- Allow: checked
Reset Timer
That is helpful if you wish to preserve monitor of how lengthy you’ve been flying. Additionally very helpful if you happen to depend on timers for battery administration and determine when to land.
I usually use my Arm change to set off the timer, and after I disarm, it routinely resets it.
You begin the timer within the Mannequin Setup Web page below Timer 1 utilizing your arm change (arm place):
Then in Particular Perform you’ll be able to reset Timer 1 utilizing the arm change (disarm place).
It’s also possible to set a voice shout out each minute to remind your self how lengthy you’ve been flying.
Override Channel
You may pressure a channel to a hard and fast worth utilizing a change, it doesn’t matter what the sticks, inputs, or mixes are doing.
A standard use is Throttle Reduce, the place I usually use on my mounted 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
- Perform: 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 will probably report:
- telemetry values like GPS coordinates and battery voltage
- stick positions
- radio states
- and different helpful information
Logs are saved to the SD card and might 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 all the time logging)
- Perform: SD Logs
- Worth: 1s or 0.5s (logging interval)
- Allow: checked
I’ve a tutorial explaining set this as much as log and think about GPS information: https://oscarliang.com/log-telemetry/
Screenshot
This takes a screenshot of the radio display screen and saves it to the SD card.
I make tutorials, so I discover it to be very helpful. For abnormal pilots, possibly it’s helpful for sharing your radio configurations on-line, or wish to preserve a report of settings.
Professional Suggestions
- Allow checkbox — Double-check this each time. It’s the #1 cause Particular Capabilities don’t work.
- Order issues — Particular Capabilities run from high to backside. Conflicting features could also be overridden by decrease strains.
- Voice information — Be certain 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., computerized warnings based mostly on timer, telemetry information, or different circumstances).
Ultimate Ideas
In case you are not utilizing Particular Capabilities in your EdgeTX Radio, you might be lacking out! It turns your EdgeTX radio from a fundamental transmitter into a wise, useful instrument. Particular Capabilities in EdgeTX just isn’t probably the most advanced a part of the radio, however it’s actually one of the crucial helpful. When you perceive the fundamental concept of set off + motion, the entire menu turns into a lot simpler to know and use.
