What are you guys using the momentary buttons for? I don't have any installed but I was thinking I'd like to use one for an "oh crap" button. I was thinking it could work by temporary sending whatever value on whatever channel that the flight switch is on (temporarily changing it back to angle mode but ONLY while the switch is held).
Is that something possible? What are you using the switches for?

Momentary switches can be useful for a lot of things. Most of the small video quad ini's use a trim switch to turn on/off the video or to snap a photo. Some use them for auto-flip. You could certainly assign one to "Safe" mode or whatever (in my Blade 200srx, channel 6 is used for that).

For the switches we've added in this thread, they are a PPM input, and through the magic of DevoTX you can assign the switch to ANY channel on your bird. So if I set up my Arduino PPM channel 1 for a momentary switch, I would set up my mixer for channel 6 to use PPM1 as the SRC, use default 1-to-1 curve, default scale of 100. Then when I press the switch, the value on Channel 6 goes to max and I get Safe mode until I release. Unfortunately I haven't figured out how to use PPM input in the emulator :(
[channel6]
max=100
min=-100
template=simple
[mixer]
src=PPM1
dest=Ch6

I can't test this code because I've set all my momentary switches up in analog on my Arduino; it works with my 3-way switches just fine. So please let me know if this doesn't work for you.

BTW can u explain how to use virtual channels to use that 3ways switch to control dual rate?
thanks

I've got no idea on the compiling error. I edited the code a couple times, right after posting, I noticed a few syntax errors. Did you copy it within 10 minutes or so of the original post?

For rates, you should actually be fine with the original setup. Deviation's Dual Rate/Expo mixer only requires 2 switch positions to select mid & low, high is default if otherwise. So just set the switch for Mid to PPM3 (or PPM4) and the switch for Low to !PPM3 (or !PPM4).
It should work,.............I think.

tried copy many times and compile but till same error. my programming skill is limited, to couldn't figure out what went wrong.
will try to do that PPM3 & !PPM3 setup and see. (still learning how to use deviationTX)

Which board did you compile it for, the Mini or Nano? Was the IDE set to the right board?

google around and found out it is something to do with arduino software & windows xp.
compile using windows 10 , everything run perfectly.
Your code run perfectly :) :) ...my mistake for still using windows XP :lol:

:whistle: .... IDE 1.0.6 and 1.6.1 still running fine with XP.
My advice, especially for those who are doing much technical stuff, preserve at least one of your previous OS as dual boot....

tried this but does not work. set !ppm3 70%, ppm3 30% and the high rate is 100%. when i flick the switch it will toggle between 70% and 30% but never go to 100%.

That's because you only get the default mode if both switches are off. If the two switches are PPM3 and !PPM3, clearly one of them is always on. You needed to use two channels for this.

Just for the record, you can use the existing trim switches and left/right/up/down/exit buttons as momentary buttons without adding a hardware. As noted, they get used for camera control and flip mode on toy grade quads (I'd hardly call my V323 "small"). I tend to use a switch for flip mode. I also use one for mode control on my NanoQX.

I've been on the fence for a bit now. Trying to figure out how to disfigure one of my 7e's. I have flip on a switch for most of my quad collection. Pardon my French, but It sucks! So I seldom do flips. Auto-flip mode is a nasty accident waiting to happen, and flipping a switch back and forth is not much better. The otherwise awful toy radios come with wonderful little buttons, positioned right where they belong -- under your index fingers. (Thumb flier.) Someone recently posted a photo (can't find it just now) of his added button on the shoulder of his 7e. That's wonderful, easy. Mandatory. :-) The 7e shoulders deserve several momentary pushbuttons. And deserving pilots should have them available. Good stuff. Probably the most important upgrade for those with collections of toy quads. After Deviation itself, of course.

(Stuff is hard to find on this site. Not so well organized or instrumented. It could use some help. Especially a smarter, google-style, search.

Crud, so if switch is -100, would it have to go to +100 to be considered off or just to the positive side (+1)?

Easiest way is to parallel a momentary or two off of your throttle trim buttons. Or if you happen to have a 2 pin JST connector you can plug your new buttons in place of the trims.
I personally would add an Arduino and a bazillion switches, just sayin. :lol:

A momentary switch wired in parallel to the FMode switch would be easy to add and fit nicely on the right shoulder of the 7e. I have several models that use the FMode for flip mode, and my Blade Safe switch would work better with a momentary button too. This wouldn't need an Arduino. For $1.77 a pair at BG I'm in.

So is it a way to set -100,0,+100 3ways switch as a dual rate switch (ie: 100%, 70%, 50%)??

There are no -100,0,100 switches in deviation. A switch is either on (1 or more) of off (-1 or less, and I never do remember which 0 is). A three position switch is three switches in the firmware, like FMODE0, FMODE1 and FMODE2 that are all either on our off.

So to use a 3 position switch for 3 flight modes, you use two of those three switches for two rates and the third position is your default.

Just tried setting up one of my Arduino-connected 3-ways for dual rate. In the 0 position it fluttered between mid & low.

davidwyl, have you tried the code that split the 3-ways into six 2-ways? You'll end up with PPM3,4, & 5 as the 3 positions of one switch. Just set Mid to PPM3 or 5, and Low to PPM5 or 3. The middle, PPM4 won't be used. Well, you could set PPM4 as a switch for something you want active along with High rates.

In your code when you test the two digital pins of the three-way switch, I noticed that you are doing redundant testing, which, IMHO, may be the source of the fiddly results. Here's what I mean:

Your code tests Pin 2 for ==0, and if true assigns the PPM value for low. If the result is FALSE, you test for the state of Pin 2 and Pin 3, but this is not needed, because we already know Pin 2 is on, and if Pin 2 is on, Pin 3 cannot be on (on a 3-way On-Off-On switch). Here's the code:
// 3-way switch #1
  // Position 1
  if (digitalRead(inPinD2) == 0) {
           sw1_uS = 750;
  } else {
           sw1_uS = 1625;
 }
  // Position 2
  if ((digitalRead(inPinD2) == 1) && (digitalRead(inPinD3) == 1)) {
           sw2_uS = 750;
  } else {
           sw2_uS = 1625;
 }
  // Position 3
if (digitalRead(inPinD3) == 0) {
           sw3_uS = 750;
  } else {
           sw3_uS = 1625; 
 }

In my code I am setting the pins HIGH, then when the switch goes on it is grounded, so the value goes to 0. Once you test the state of Pin 2, you have only two possibilities for Pin 3. So my code tests to see if Pin 2 is NOT ON, which if TRUE, means it's off and we do not need to test Pin 3. If it is FALSE, we know Pin 2 is ON, and we need to find the state of Pin 3. I think if you simplify the code you'll make the jitters go away:
if (digitalRead(swPin_D1) != 1) { // 3-way Switch 1
           sw1_uS = pulseMin;
  } else {
           if (digitalRead(swPin_D2) != 1 ) {
            sw1_uS = pulseMax;
  }        else {
            sw1_uS = pulseMid;
            }
  }

I don't know if this helps your particular installation, but I'm not having any issues with the two 3-way switches, one assigned to PPM1 (-100, 0, 100) and one assigned to PPM2 (-100,0,100).

Excellent point, Deal57. Yeah I've got a lot of cleaning up/simplifying to do. Thanks.
