Using a momentary switch as an on/off toggle switch in ETHOS

[@JunaidKhan-xm3ch]

just watched this video, i have recently purchased the x20s, after being with spektrum since they started. the x20s is so different to use compared with what im used to. your videos are going to be a big help to me during my transmission period to frsky, i have over 20 aircraft to set up , jets and helicopters. thanks for doing these videos they are really helpful

[@MrD]

Welcome to the X20S and FrSky. I'm glad the videos are helping with the transition from Spektrum. I hope all the re-maidens go well.

Using this to toggle the 3W headlights i put on my quad

[@MrD]

Cool. Nice use case 👍🏻

[@cx9drvr]

This is an excellent feature tip. I want to use one of the back buttons for Smoke On and Smoke Off. Thanks.

[@MrD]

You’re welcome Randy. Glad it was helpful.

Just used this on my -Antonio Banderas- , umm _Zorro._ With only 4 switches, (Arm 2p, AutoTune 2p, Flight mode 3p, and GPS mode 3p) I was out out of switches on the little guy! But after watching your AutoLaunch video, I was in need of a new toggle! Originally, I tried to use the weird roll-y detent-less wheels on the radio (what are these for?!), but I decided I'm not going to be a savage, and find a better way to let the robots take over. Since Antonio has 2 momentaries on his back, like your Ethos, I put my sticky on the right side of his back (this got weird). Thank you, Big D.

[@MrD]

Yeah, that trick works just as well on OpenTX (which freedom tx is a fork of).

[@MATTIIAO]

Absolutely brilliant as always!! Thank you.

[@MrD]

Thank you. I'm glad it helped.

[@tomgulizia113]

I used the back buttons to turn on lights and Rev motor on night tundra. THANKS FOR THE HELP. I TRIED USING MY LIPO SENSOR THAT I USE ON ALL MY PLANES WITH ACCESS RX.

[@tomgulizia113]

When I plug into the td10 small white plug on the rx. I tried to discover sensors and it found nothing. I shut down to study more and when I started the x20 my model was gone from the select model screen. I'm missing something easy.

[@hobie278]

Hi Tom did you setup the reverse for reverse thrust? If you did could you tell me how you did it? I have a plane with reverse thrust but i have to hold the switch and give throttle when i land but want to put it on a switch so when i flip it it goes to full throttle without holding switch. Thanks.

[@emmanuelsab1095]

brilliant!

[@MrD]

Thanks Emmanuel 👍🏻

[@qyitonefpv6551]

Awesome tutorial Darren. Tried this last year and couldn't get it to work properly. Seems there is a fine line of flipping the switch to fast or too slow. Too fast and it wouldn't switch to the up position, would just fall back to the down position. All is working well now. 🍻

[@MrD]

Awesome Shawn 👍🏻

[@Simbuilds-ud2kn]

thanks for the infio. just programmed my x20s throttle toggle switch on right side. not sure why they made it momentary switch. Question: how can have it turn enable throttle cut (disable throttle) when powering on transmitter?

[@ohgiloo]

Very interresting i will use it thanks !

[@MrD]

Thanks Gilles.

[@iheadshave7274]

Could you please post a video about turning the screen off when the throttle cut switch is armed?

[@MrD]

I don’t believe there are any special functions to switch off the screen. The throttle cut detection is simple, as that is built in to ETHOS. I believe it’s in the system list.

[@eoinj3929]

Hi Darren, Can you do an Ethos version of Andrew Newton s recent video showing the voice calling out a value of a Po S2. Thanks Eoin

[@MrD]

Hi Eoin, Sure, that’s no problem 👍🏻

[@ChunkyC_RC]

Ooooo I like this one 😁

[@MrD]

Thanks Chris 👍🏻

[@emmanuelsab1095]

by the way, do you know how to substitute the third position of a 3-position switch by the state of the momentary button transformed into a 2-position switch? on an SR8 receiver , the management of the gyroscopes (no gyroscope, gyros activated, panic mode) is carried out by a 3-position switch, but in panic mode, it is panic; it is sometimes difficult to activate the panic mode (you have to find the right switch, the right position, etc.) the button on the back of the transmitter is the best device for activating the panic mode without having to think , but you must be able to assign this button as the 3rd position (and priority) of the 3-position switch. well it's not easy to explain, I hope you understand the gist of it

[@hobie278]

Darren i have a plane with reverse thrust. I have it setup on a momentary switch but when i land i have to hold the switch and give it throttle. How can i just flip a switch and it will go into full power without giving throttle. I could do it with Spektrum it’s called fatigue. Can it be done on Frsky also. I’m new to this radio but learning things from you. Thanks

[@karstenhoysagk9448]

Thank you for doing this Darren. Your videos are of great help in learning Ethos. Am I correct to say that you cannot have this switch play two different sound tracks, for example "ignition armed" and "ignition disarmed" for the two positions?

[@MrD]

Thank you Karsten. Sure you can have 2 different sound files for that switch. First, make a special function for the "on" sound file. You would set the active condition to be the sticky logical switch. So when the sticky is active, the sound plays. Next, duplicate that special function. Where the sticky's logical switch is; long press the enter button. Then select "invert". Then choose the "off" sound file. You'll then have sounds for both the on and off positions of that momentary switch.

[@karstenhoysagk9448]

@@MrD you're a genius. I didn't know about long pressing the enter button. Works like a charm.

[@MrD]

I wouldn’t say genius 🤣 Anything in ETHOS where you see the little square next to the option, you can long press enter to get more options.

[@MATTIIAO]

@@MrD Exactly what i was looking for. thanks ;-]]

[@3dFirefly.]

I am looking through your video collection for how to use the 6 custom buttons on the front, couldn't find any, maybe I'm searching with the wrong keyword. Is it possible to use them for the different modes on the Stabilizer (S6R)? maybe make a video on this.

[@janoooms6257]

i have the x20 and when i move my transmitter up and down my height rudder also goes up and down, i think the gyro in my transmitter, how do i get it turned off?

[@MrD]

It won’t do this unless you have changed the mixer to use the gyro. Check the elevator mixer’s source.

[@mabbs2757]

Darren could you have it doing multiple functions doing long and short presses ?

[@MrD]

Sure Brian. You could set up edge logical switches that will trigger with different timings. For example one with 0 to 0.5 seconds for clicks. Then another that is immediately triggered after 0.5 seconds (I believe the immediate trigger is called “rising edge”; but I’m not at a transmitter to confirm). Then use those logical switches to activate and deactivate the stickys. I don’t mean to be picky. But, I’m not keen on Daz. D or Darren is fine though 👍🏻

[@janoooms6257]

I have an x20 transmitter and if I enter tap sheet sxr device config then I can't click anything here? maybe you know a solution

[@MrD]

This will be resolved in a future version of ETHOS. FrSky are working on it now.

[@hahnsmantra7276]

I'm thinking I could use this switch as my rescue (oh crap switch) being that this is a reflex action, I won't have to mindfully flip it back, just let go and I can resume control of the heli after it pulls out of me crashing the aircraft

[@MrD]

Not in the example I use. That will latch until you press the button again. To use it as an "oh crap" switch, you just need to set up a mixer to output the needed value when you hold in the momentary switch.

[@hahnsmantra7276]

@@MrD I see....still good though, pulling up in the same direction to activate and release rescue would be cool

[@EnriqueIvanHoward]

Hello Darren, how would you trigger to play two different files, one for each state condition? I am using this to trigger throtle cut and would like to play a sound for throttle cut on and throttle cut off. I am totally new to the FrSky ETHOS ecosystem and your videos have been my tutor.

[@MrD]

Hi Enrique. Yes, that is fine. You just need to create a couple of special functions to play the sounds for the throttle cut. If you're using ETHOS' throttle cut function, it's even easier. Create a new special function with the action "Play Track". For the Active Condition use System Event for the Category, and Throttle cut for the action. Next assign the sound file and don't forget to set the state to Enable. So now, when you activate the throttle cut, the track will play. Now make a copy of that special function and edit it. Long press on the Active Condition and select "Invert". Then change the sound to the throttle cut off sound. Then both sides of the switch will work.

[@EnriqueIvanHoward]

@@MrD That worked! Thank you.

[@MrD]

You’re welcome

[@Rosatisp]

Hello Darren, I've set the Special Funcs (Play Track) to my airplane however when I created a new model for my drone racer I could not create new functions to the same switches. Do you know anyway to do it? Example: where I have the Flap switch to the airplane I want to have the Flight Mode switch for the drone.

[@MrD]

There shouldn’t be anything stopping you from doing that. Each model you can set up as you wish.

[@Rosatisp]

@@MrD that was my thought. In your radio when you create a new, is the Spec Function Page empty?

[@MrD]

Yes. Every model has its own special functions.

[@Rosatisp]

@@MrD I've contacted Frsky and they told me that on the Special Funcs page I need to turn off the Global variables, so the previous set will be invalid. Now it is solved. Thanks.

[@MrD]

Ah, I’ve not used the global special functions. I’d have thought that only the function you set as global should work everywhere. But you’d still have the option of adding more model specific functions.

[@emmanuelsab1095]

Darren; on ethos 1.4.8 there is no more any "sticky" behaviour. what do we have to choose then?

[@MrD]

The sticky logic switch is there. It’s at the bottom of the list of switch types.

[@emmanuelsab1095]

@@MrD ya! in french version, the name is "sécurité armement"

[@smdub]

Is there a way to use a long switch hold to disable the throttle cut. I would like a quick tap of SH to enable throttle cut (turn off the throttle) but want to have to hold SH for a second or two to disable throttle cut. Prevent inadvertent enabling of a motor. Do I have to create a mix with a delay and then use that mix as the trigger off condition? I haven't been able to figure out a combination that works.

[@smdub]

I figured this out (typing out the problem above helped me think it through). I created another logic sw called 'SH Hold'. Thats a 'sticky' w/ trigger on=SH(down), trigger off=SH(up). Delay before active = 2.0s. So now when I hold SH for >2S the 'SH Hold' logic sw goes active. Goes inactive the instant I release. Then I went back into the throttle kill like you programmed in this video and changed my trigger off=SH Hold. Works like a charm.

[@MrD]

Awesome Stephen. Glad you got it figured out.

[@smdub]

@@MrD Since it doesn't appear that I can default a logic swith to active at turn on (or loading a new model), I actually inverted the logic and converted this to 'throttle arm'. That way when I load a model the motor is safely disarmed by default. I use !throttle_arm in the throttle channel for cut. Thanks for your videos. Several have been helpful getting the hang of Ethos. I sub'ed.

[@pfeffery]

Can I use the momentary switch to turn a timer off/off? This technique doesn't seem to serve that function.

[@MrD]

Assuming your mean on/off, yes, this will work fine. Just use the logical switch as the active condition for timer.
