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

Hey Silpstream, I was wondering is there still progress on the possibility for adding the extra switches combination, such as:
2x 3way and 6x 2way
4x 3Way and 4x 2way
I still have room for two more switches and actually therefore I did not yet wired up yet the extra switches
If not anymore in the pipe, no problem and then will hook up 4x 3 2x 2 as per instruction of thios topic.
Anyway I do not mind to use an extra GPIO pin.

@fernandez, I just finished the new code but got some compile warnings to work out. I also need to put a bit of documentation together so that you can wire it up. Give me a few more hours then get ready to test. Thanks!

No rush, take your time.
Was just wondering if this idea was still in the pipe, or that it was decided to stop.

Anyway good to hear

Hi guys, I just uploaded a new build that will enable different combinations of switches: deviation-devo7e-256-v5.0.0-swcfg-0bf38cc .

We can now have a maximum of 8 switches (A - H). Possible switch combinations are:



Only the above combinations are supported. Naming convention is number of switch positions x number of switches. Example: 3x2 = 3-way x 2 switches, 2x5 = 2-way x 5 switches.

Configuration for the above is from hardware.ini. The option "extra-switches=nostock" now needs to be added if this mod is used to tell the firmware that the stock HOLD/FMOD switches have been removed. If you are using the previous (original 3x2/3x1/2x2) devo7e switch mod, then do not add the "nostock" option.

My config (new u7e switch mod with 3x4, 2x2, potx2):
Example (original devo7e switch mod with 3x2):
Given that we now have switches A - H, the 2-way switches have been shifted to ease the conditional logic used. As such, take note that you'll need to update your model.ini files for the new switch names. Basically:3-way switches start from A and move forwards to D. 2-way switches start from H and go backwards to A. Thus 3x4, 2x2 would give us: SWA, SWB, SWC, SWD, SWG, and SWH.

Here's how the wiring should go.



Basically just wire based on the switch config that you want. For example if you are doing 3x4, 2x2, then wire based on 3x1, 3x2, 3x3, 3x4, 2x1, 2x2. If you are doing 3x2, 2x6, then wire based on 3x1, 3x2, 2x1, 2x2, 2x3, 2x4, 2x5, 2x6. Don't forget the diodes as shown.

Please help me test it on both the original switch mod and the u7e switch mod. Thanks guys!

It looks very promising but can you please explain, the switches naming as I found confusing what means what.

I always thought.
2x2, means 2pcs a 2 position switch.
2x3, means 2pcs a 3 position switch.

In my ideal case I like to put 3pcs 3way and 3 pcs 2way.

Actually the naming convention in deviationtx has been:

3x2 = 3-way x 2
2x1 = 2-way x 1

In your case you will want 3x3, 2x3.

Ahh ok clear, actually btw I meant 4 2way and 4 3way, so I am planning to follow your color coding and wire up my u7e like this;
4x3 - SWA, SWB, SWC, SWD
4x2 - SWE, SWF, SWG, SWH
Potx2

Take some time, but certainly will do and revert back

You can't do 3x4 with 2x4. Check the combinations i posted above for possible combinations. I just edited it to make it clearer.

Could you also test first with your existing switch mod? I'd like to know if it works for the original switch mod. Thanks!

Just to confirm I have just loaded firmware post #50865, deviation-devo7e-256-v5.0.0-swcfg-0bf38cc, into my U7E.
It detects pefectly fine my original devo 7e, 4 switches configuration 2x3 and 2x2.

Only thing, it is missing the Frsky X-protocol, which was in previous U7E build.

Thanks for testing! I'm building these based on BRANCH_5.0. After everything works, I'll then merge it to the nightly build.

I have build the 3x2 2x6, I basically used some flat cable and wired the lines from the back of 7e pcb
in following order:
Left to right: PB6 blue-PB5 light blue-PC10 Pink-PC11 Red -PB7 Green -PC6 Yellow -PB8 Orange

The switch layout seen from back of the Tx, see the image sketch attached.


My hardware.ini looks like this:

---

;Only useful for transmitters with an after-market vibration motor
;enable-haptic=1
;
;switch_types: 3x4, 3x3, 3x2, 3x1, 2x2, 2x1, potx2, potx1
;May occur more than once if necessary.
extra-switches = nostock
extra-switches = 3x2
extra-switches = 2x4
extra-switches = potx2



;button_types: trim-all, trim-(left|right)-(up|down|both)
;May occur more than once if necessary.
;extra-buttons=

;txid = 78968765

; enable-cyrf6936 = B12

enable-cc2500 = A13
has_pa-cc2500 = 1
enable-a7105 = A14
has_pa-a7105 = 1
enable-nrf24l01 = A15
has_pa-nrf24l01 = 1
; enable-multimod = A13

Anyway there is some response from switches but all is weird I cant put the finger on it, there is something wrong, switches interact sometimes change label depending on other switches etc, sometimes don't work.

I thought I have wired all pretty securely, according your colour drawing, see also photo, but now will first double check it, currently it is not ok.

@Fernandez, I must apologise. After reading your post, I rechecked my wiring diagram and realised that there was an error for 2x5 and 2x6. I confused PB6 and PC6. I've corrected it and uploaded the new diagram above.

Also, your hardware.ini should be 2x6 not 2x4.

Hopefully this sorts it out. Again, I'm really sorry for the error.

I double checked the wiring according your diagrams I double checked the diodes polarity.
But it seem all is wired correct.

It seem there is some bug in the matrix or software?

Ah ok 2x6, but basically the 2 stock switches must be included?
will try check your update.

You basically want the following in your hardware.ini:

"nostock" removes the stock switches, so 2x6 defines all the newly wired in switches.

The updated wiring diagram is in post #50865 .

There is some progress, changed ini and changed yello to blue as suggested.
It is better but there still are problems somewere.

the way I tested it just to flip a switch and check how it is being detected in the display.

2x1 - no detection
2x2 - no detection
2x3 - F0-F1
2x4 - D1-E1
2x5 - C1-D1
2x6 - C0-C1 ok
3x1 - no detection
3x2 - B0-B1-B2 ok

so still some errors in software or matrix

@Fernandez, I got home after work today and tore apart my 7E to test the switch mod and check my wiring diagram.

To my horror the diagram I gave you was WRONG a second time. I'm feeling really dumb now, really sorry AGAIN.

I've updated it AGAIN and updated post #50865. Hopefully this is the last time, cause I really checked and rechecked with my TX open and wired for 3x2, 2x6. Here's a video of the result.

No problem Silp, I appreciated your work, I have been volunteer to test it
Anyway I can recommend anyone to put a piece of flat cable to the mid of tx, from there you have all connection points from left to right and can easy and neat wire to all switches. It is also relatively simple to change, just shift some wires here length stay same, I did not yet shrink the sleeves.

Will test and let you know.

Almost working but still there seem to be an issue......

I'll check a bit different, just toggle a switch, and then read the swith label in the settings field in a channel.
The current status is:
3x1 - A0-A1-A2
3x2 - B0-B1-B2
2x1 - H0-H1
2x2 - G0-G1
2x3 - E1-D1
2x4 - F0-F1
2x5 - C0-C1
2x6 - D1-C1

The 2x3 and 2x6 are incorrect, switch labels on toggle.
The labels itself seem not correct, would expect 2x1 to be C and 2x2 to be D etc etc.

I think I fixed it. Try deviation-devo7e-256-v5.0.0-swcfg-990acaa .

The 2-way switches go backwards starting from SWH (2x1) anding in SWA(2x8). The 3-way switches go forward from SWA (3x1) to SWD (3x4). They meet in the middle depending on switches configured.

Your 2x3 and 2x4 as well as 2x5 and 2x6 wires for red and pink are reversed so you see them flipped. Don't need to re-solder, just move the switches in the housing.

Bang it works after the update, all 8 switches are fine now.

I'll make some pictures and short description later, for others want to copy the build 2x3 + 2x6 + 2 pots.
Still I believe might make sence, just to change the labels of switches, so that lower switch label also have the lower letters.

such 3x1 A
3x2 B
2x1 C
2x2 D
2x3 E
etc....
