Programming 3-way switches

Hey everyone!!!!!

I know most people will respond to read the manual.. well I DID!!!!
I have long ago installed 2x 3-way switches as well as an NRF module and I have also done the range mod on my Devo 7e!!!

It works absolutely awesome so far with one exception.... I can not figure out how to actually USE my 3 way switches!!!

I wired them with diodes and everything, they show up fine as SWA and SWB with 0, 1 and 2 positions working properly!!
(yes I properly configured them in the hardware.ini file)

One thing I have NEVER found is this.....

What do I need to do to use them????? Are they completely different than the stock 2 way switches????

For example, on my EOX I already have a model.ini file working great, but I would love to use the 3 way switches for flight modes etc. but I simply cannot figure out how to do this..... It works fine for the stock 2 way switches but after many attempts I cannot figure out how to set it up to use the 3 way switches....

Example.. this is my Ch5......
Works fine for switching between Sport and Expert modes....

[channel5]
max=100
min=0
template=simple
[mixer]
src=HOLD1
dest=Ch5
curvetype=min/max
points=0

In order to use the SWA and SWB switches, do I have to set up a mixer for each position of the switch???
What I mean is have a mixer for each position like this....

[channel5]
src=SWA0
max=100
min=-100
[mixer]
src=SWA0
dest=Ch5
curvetype=min/max
points=-100
[mixer]
src=SWA1
dest=Ch5
curvetype=min/max
points=0
[mixer]
src=SWA2
dest=Ch5
curvetype=min/max
points=100

If someone could PLEASE help me learn how to program these switches I would be VERY grateful!!!!!!
The HOLD and FMODE work absolutely fine but I cannot figure out the programming to use my 3 way switches.....

Here is my DEVO8S setting for EOX ch5.
You can change it into 7E format.

[channel5]
template=expo_dr
[mixer]
src=FMODE0
dest=Ch5
scalar=-100
curvetype=fixed
[mixer]
src=FMODE0
dest=Ch5
switch=FMODE1
scalar=0
curvetype=fixed
[mixer]
src=FMODE0
dest=Ch5
switch=FMODE2
curvetype=fixed

You need to use them as SWITCHES, not SRC's.

Try reading my tutorial on writing model files .

So, technically if I replace all of the FMODE in this with SWA or SWB, in theory this should replace my FMODE 2-way switch with my added 3-way switch?
As I stated above, my HOLD and FMODE switches transmit just fine to the RX and FCB and I can see the inputs change in Cleanflight and can use them for switching modes etc. but 2x 2-way switches is quite insufficient for setting up flight modes and AH, PH and RTH... This is why I need to change Ch5 and 6 to my 3-way switches.

Actually, this is the exact mixer that enables HOLD and FMODE switch perfectly fine...

[channel5]
template=simple
[mixer]
src=HOLD0
dest=Ch5

[channel6]
template=simple
[mixer]
src=FMODE0
dest=Ch6

It registers them as about 1900 when in "0" position and about 1100 in "1" position in cleanflight GUI. I have seen 3-way switches on a different TX used for 1100-1500-1900 quite well and this is what I am attempting to do....

MWM... I am already reading your guide thanks for doing all that work!!! But honestly I have had my 3-way switches installed for a few months now and I dont think I have been able to locate even one single "working" mixer for the new switches... Even in your tutorial the switches are being used quite differently, they are used to modify scalars for stick inputs to change the rates or AIL etc. For flight modes on my 2 quads I only need the switch position to be sent to the RX and the programming is done on the FCB side. So a simple mixer setup for this is what I am looking for, I understand how to program it to change RUD to an expo curve when FMODE1 is active and normal straight line curve at FMODE0, but this really does me no good for my setup.

PROBLEM SOLVED!!!!!

After messing around for hours I finally got it figured out!!! Long story short, you cannot use "SWA0" and "SWA1", you must use a space between them like this... "SW A0" and "SW A1"!!!

Here is my final code and it works PERFECTLY!!!!! I get @1900 on SW A0, @1500 on SW A1, and @1100 on SW A2..... This opens up a LOT of programming choices for flight modes etc...

Again, I am using a fully modified Devo 7e TX, with a Naze32 FCB, Orange RX 6 channel R615X, and I am using cleanflight 1.9....

Thanks for all the help and hopefully this will help a lot of other people like myself in the future!!!!!!

Awesome!

Works for me too

Just for the record, there is a section on doing that. It coverts a number of ways to select from the three flight modes on the 200QX with the FMODE switch. Given what you just posted, you might want to read through it. For instance, the SRC on all your mixes is ignored because the curve type is fixed.

But yeah, it's hard to get the switches to work right if you don't have the names right. But if you look at the names on the Tx, they are "SW A0", SW A1", and so on, with the space. At least, they are with the latest nightly build.

Perhaps that is my problem as I still am using a much older nightly build from May I believe!!! My other problem was that I was trying to do everything using notepad+ instead of using the mixers tab on the TX as it was very confusing to me!!! After spending the time to figure it out and testing it while plugged into the FCB I was then able to actually see the code that the TX made for me....

I guess I was trying to do it backwards......

I trust you that the SRC is ignored but seeing as I am still learning the mixers I thought it made sense the way I did it.... either way, it works perfectly for what I need it to do. I would rather have TOO much info in it than not enough.....

FWIW, I will continue reading through your instructional write up when I am done with this quad!!!


Lastly I wanted to add this......

I know it is always best to actually KNOW what you are doing and why, but I have seen a lot of people looking for help on this topic, yet the only answers anyone ever got was "READ the manual" or "READ this or that, blah blah blah". While it does not really TEACH them anything, why would absolutely NO ONE, including yourself simply post a quick code similar to the one I just posted???????

Again, it doesnt teach them anything, but it would actually get their TX working with the new 3-way switches, it would allow people in the future to use the code and not post another question on the same topic, and it would also be a starting point to actually learning how and why it works the way it does... At least for me, knowing quite a few different programming languages, actually seeing the code helps me understand it better!!!!

I have in the past posted short things. And I will probably keep doing that.

But I don't have a 7E, and have never had one with any extra switches, or had one after deviation had support for the extra switches in the standard build. So I can't post a simple example and know that it would work. I could post an example I know worked on my 10, and an explanation of why it works in hopes that would help you. But I did that so often I decided to write it up and put it all in one place. That way, I can correct it as time changes, let other people contribute, and not have to type it in over and over again with possible new errors each time.

Of course, none of that would have helped you because your problem wasn't from not understanding the mixers, but because you got the switch names wrong. That possibility never even occurred to me. Nuts, if you looked at the Wiki page listing the switch names, I got them wrong there myself (fixed now, and you deserve some thanks for that!). So I may have contributed to your problem. I don't remember where I got them from, though...

Its all good!!!! I just found it really strange that I have only ever seen people asking questions on how to use the added 3-way switches, but I have never come across an actual answer.... And I have become quite good at google searching!!!

As I said, hopefully this thread will help many others as it has already helped DoubleQuad!!!

I have absolutely no problems with anyone "streamlining" the code I posted to do the same thing with less lines etc...

hi all
I am having the same issue.

I am using a devo10 with RX1002 receiver and CC3D atom FC for a mini 250 sized quad

when I use open pilot the auto setup sticks on the flight mode switch.

I read the manual but as I have updated to deviation firmware the menu's appear different and I can't find the "device" option to select and set up the flight mode switch.

I have tried several amended .ini files and none seem to work sometimes even causing the auto set up to stall at the rudder stage.

I'm clearly doing something wrong so any help or suggestions would be great, below is my .ini file WITHOUT any modifications, I know I need to add a section for [channel5] but what and where are driving me insane. this is my first build so struggling slightly with how to move on.

This is the one I use with my CC3D on a 250 FPV quad with a Devo 7E
the 2 x 3 way switches I have configured
left one is currently used for turning the lost vehicle alarm on and off (have to configure the extra output in OpenPilot for it to work)
right hand one is for selecting the 3 flight modes on the CC3D FC - switch up is mode 1, switch center is mode 2 and switch to the bottom is mode 3

They are set to output -125 0 and +125 for each position using a 3 way complex mix deadband for the 3 values

thanks, unfortunately I am not 100% sure what to change from the devo7 to make applicable to the devo 10. I have tried adding the [channel5] code from another source but it still wouldn't work and I must have done something wrong as the set up stuck at the rudder input 1 earlier
I can tell you it's been driving me mad today.
This is my first build and set up so have limited knowledge but trying to learn albeit slowly

+Mynci, what you're doing wrong is using the Standard gui. It's designed for dealing with CP heli's with flybars instead of flight controllers, and doesn't have any facilities for dealing with a modern flight controller. Which is why you can't find the switch you're looking for.

if you really want to use the standard GUI, you can use the "gyro" facilities for it. Use "Switch assignment" to set the Gyro sense switch to whatever switch you want to use. Make sure that NOTHING ELSE is using that switch. The default is "MIX" which should work fine, but feels odd to me. Then go to "Gyro Sense" and set the channel - looks like you want "GEAR/Ch5" - and then set the values to 100%, 0, and -100% as you like.

Frankly, if your current model isn't working, I'd throw it out and start over using the advanced GUI. The tutorial I referenced earlier will walk you through setting up a 200QX, which uses the channel five for flight mode like you're trying to do. You might not be able (or want) to use the "stagility mode" and automatic in initialization, but that much should work. It's done with a Devo 10 as well.

Thanks, just what I needed

Take care when using with a Frsky ppm receiver d4r-ii, the ppm can overflow and can crash your vehicle, when all inputs at max range or close to max range.

So channel 1-4, set to 125% throw, 1000-2000ms, 1500neutral. (required for Betaflight/Cleanfligtht, otherwise can't arm)
Switches set them to 50% throw, -50-0-+50%, it does not harm to make range smaller, as in the Flight controller you have to set the switch detections. plenty of resolution.

I'm using AR7700 1-4 at 100% it ARM's allright. You are right I'll change the scale just in case. Thanks

Then there is this. Best explanation of tx switch programming i have found.
