Ultimate7e tutorial: Four 3-way + two 2-way switch

Finally managed to add four 3-way switches to the devo7e. It requires an upgraded processor due to space constraints. The tutorial is at:

Ultimate7e: Adding 4 extra 3-way switches

Here's a vid of it:



This modification requires upgrading of the Devo7E processor. The link for how to do it is below.

Test builds are available on the deviationtx site (Downloads -> Test Builds ). There you'll find:

• [silpstream]Ultimate7e-v5.0.0: Test Builds - Build based on BRANCH_5.0.0 (Latest stable release with bug fix updates only).
• [HappyHarry]Ultimate7e Deviation5.0.0-xxxxxxxx - Build based on nightlies (Latest and greatest deviationtx features get tested here).

[UPDATE: 12 July 2016] Now supports Multiple switch configurations. Check this post .

nice work bud!

btw i noticed you used kynar for hooking the pots to the mcu, do you think it would carry enough current for the 3ways as well? as it would save a lot of space using that small a wire!

Those sliders look similar to the Taranis x9d ones. It'll be interesting to see how you get it to fit. Might be easier to use 60 degree pots and 3d print your own solder type knob. Let us know how it turns out. You can scavenge some small 60 degree pots from the gimbals of some toy transmitters. They have short necks and are rather slim, so might work well.

I am actually using a 36awg teflon wire (from hobbyking) and not Kynar, but for the mcu part they should both work.

I also don't see why Kynar would not handle the current for the switches. I believe the traces on the pcb would be slightly smaller than the Kynar, so you should be ok. Barely any current is going through it anyhow. In my case I scavenged the wire from an old apple usb to 30pin iPad connector. Just remove the exterior sleeve and you get soft supple fine gauge wire that is easy to work with.

Hope you don't mind me moving the discussion to this thread. It'll be easier to keep relevant information together for future searches.

yeah the taranis x9d/+ was based on the shell of the JR pcm9x/dsmx9/9303, all the changed was the rotary encoder for switches and the 2way momentary switches for pots. I've often wondered if the taranis motherboard would work with the rest of my jr 9x hardware, would be a nice upgrade if it did, but that's a story for another time lol. I was thinking of cutting some of the shell away in the relative spot and 3d printing a suitable piece to mount them so they sit flush, but we'll see how things go.

the only smallish guage wire I have is a little stiff, and still quite thick and by the time I had the modules and switch wiring in it was a little crowded, so replacing that with something smaller and more flexible would be ideal, especially now I'll be adding even more switches lol. I have a good bit of different colored kynar left over from my xbox and ps chipping days (that's what I used to jump the diode pads for the range mod) but i'd always wondered about it's ability for use for the modules (not for + or - of course) and switches being so thin.

no worries at all, makes perfect sense bud

For digital signals like our switches and spi, I'm quite sure the kynar is sufficient. Afterall, kynar was designed for fairly complex digital wire-wrapped prototyping.

I'm guessing even the pots would not be an issue. Heck, we see thinner wire running to the tail motors in micro-helis.

that's good to hear and will make things much less crowded in there

kynar is the company that makes the specific wire wrap wire I have >> Kynar it was said to be the best available back when I bought it being that it's silver plated copper with the kynar coating, actual wire i have >> Kynar 30awg but who knows if it's any different to other wire wrap's that are available lol

MCU upgrade for my soldering station, no problem.
only docker for my old notebook. Devo 7E 256 k ultimate another further away.

On the subject of wire, I use this.
m.ebay.com/itm/30awg-White-Color-Soft-Si...?nav=WATCHING_ACTIVE

30AWG Silicone stranded wire (never actually counted but I believe it's 30 strand) and most importantly it's white so I keep a bunch of different color sharpies and add my own stripe to each one. 50m will last you YEARS.

slipstream could you add changes to the code in one of your repo's to build the emulator with the required changes for these extra switches? also you have a pm bud

I'll get working on it! Also pm replied.

Emulator is fixed and git (my fork) has been updated. I'll put up the files soon, once I figure out the upload script.

Hi silpstream, for my ultimate 7e shall I also allready order the voice module?
With the new CPU and memory space, probably voice commands could then also be add to the 7e?
Willl be a tight fit

nice work bud, looks good, many thanks! i know it's probably a big ask but when you have some spare time could you add keyboard button mapping for SWA through F? as there's no way to test mixes etc using those switches without a way to toggle them in the emulator software.

[edit]
just tried to have a play about and as well as having no keyboard buttons mapped to them you can't select any of the extra switches as a source in the mixers etc, this is all way above my head so i can't even suggest where to look to enable this, sorry
[/edit]

@fernandez, i believe the extra code for the voice module will fit, but i've never looked at it so i'm not sure if it is enabled for the 7e. I'm quite sure you need a custom build if it is. @MWM may be able to shed more light on it.

@HappyHarry, it's all there. You still need to edit hardware.ini for the emulators. Add "3x4_2x2" for extra switches.

Keyboard mapping as per manual (bottom row of keyboard).

my bad bud, i had 4x3_2x2 and not 3x4_2x2 as i was going off the original switch mods way where 3x2 = 3way switch times 2, so i presumed 3x4 would be what it was looking for lol. again many thanks for this

Alls good. You do realise that i did use the existing switch-way x num-switch convention. I.e. 3x4. You might have been thinking one thing and typng another. Rolf...

jesus wth is wrong with my head lmao anyway it's clear that the problem was mine and that i need to see the doctor for a head checkup lol

I made an update to the code so that it now supports mostly any combination of switches. You can basically setup "3x3 with 2x2" or "3x4 with 2x1" or some other combination you want. Just edit the hardware.ini file to enable.

Thanks to HappyHarry for the suggestion!

that's great work bud! and no, the thanks go to you for doing the work!

this gives people the ultimate flexibility in choosing their switch combos, as like me not everyone will want to have all the switches that are possible, plus with this done they can now mod and add switches as they require instead of doing them all from the get go.

[edit]
just pulled the build off the test page, i'll give it a run through for you bud
