3rd,4th.....nth encoders not triggering on press CW and CCW for Arduino Pro Micro

[djcomber]

Describe the bug I have a button box with matirx button configuration and 3 ec11 encoders. All buttons function. Have added encoder push buttons to matrix rather than stand alone settings in simhub.

First 2 encoders operate as expected. 3rd encoder functions only on output A (pin 2) registers, Output B (pin 3) does not register Swapping pins output A (Pin 3) output (pin2) again output A registers and ouput B does not. 4th Encoder does not register inputs at all on input A or input B..

Simhub version 8.2.1

To Reproduce Steps to reproduce the behavior:

1. Go to 'Arduino Setup-> Encoders'
2. Select 'Arduino Pro Micro' as the board
3. Enable 3 Encoders
4. Add A and B pin outs for all 3 encoders,
5. Using USB controller setup up in windows any settings from Encoder 3 Output B does not register.

Expected behavior A clear and concise description of what you expected to happen.

Screenshots

Additional context It appears any pin assigned to 3rd encoder ouput B and below does not register when trigged. pins can be moved to any other encoder input and they register proving wiring is correct and Encoder is functioning as expected.

Hi ! There are some pins not supporting all kind of inputs, unfortunately arduino documentation about those lacks is really low , I think you felt into those https://github.com/SHWotever/SimHub/wiki/Arduino---Button-matrix#wiring

The pins are not the issue. As shown above I can put any of the pins with encoders on them into encoder 1 and 2 and they work fine. Any pins in encoder 3 output B and below do not register. Eg if I put pins 2,3 in encoder 1 outputs A,B it the encode wired to pins 2,3 work fine. Move pins 2,3 to encoder 3 outputs A,B in sim bun and only pin 2 will register an input. The only change was to the pin allocations in sim hub. So I don’t think I’ve wired up to a pin that doesn’t support the input.

I did suspect at the beginning that maybe I got unlucky and I tried rewiring the 3rd encoder pin 19 to other pins, same result no output from encoder 3 output B.

Then I swapped the pins allocation in sim hub and put the encoder 3 pins (4,19) on encoder 1 and put encoder 1 pins (2,3) on encoder 3. Only to find that Pin 3 that worked when allocated to encoder 1 no longer registered. And that pin 19 that didn’t work when allocated to encoder 3 output B now works fine when set to encoder 1 output B. I then iterated through each encoder pin allocation in sim hub and found that any pin set to encoder 3 B and after (Ie encoder 4,5 etc) didn’t register.

Have a closer look at the images attached and take note of the pin allocations. You’ll see what I mean. Encoders 1 and 2 worked fine with every combination. Encoder 3 only ever registered output A and encoder 4 never register either A or B.

Oh and the button matrix works fine, super easy to config that’s to sim hub.
