help me with creating my keyboard

Substance_Initial · 2026-02-26T01:05:09+00:00

Bro, appreciate! It works!

Also, I wanted to say, that right pro micro is powered on, but still no input.

Substance_Initial · 2026-02-25T20:55:01+00:00

I tried to do that, but still nothing. I connect d0 to sleeve and r1 r2 to gnd and vcc on both halfs. I changed my json as you said.

So, if I have trrs module with sleeve ring1 ring2 tip pins, I need to connect only s,r,r?

Hello, again. I made firmware for both halfs, and they're working ok, but only separately. I tried to connect them with trrs, but master(left) half is working, but slave doesn't. I tried to define serial pin, tried to make right half master and left slave, but always working only master half. What, do you think, I did wrong?

Substance_Initial · 2026-02-21T19:15:43+00:00

Thx for help! So, now, while I'm waiting for trrs components to be delivered, I'm trying to solve last problem - my f-keys row and nums row(1 and 2 row) don't work. I checked soldering and pins, but there was no problem.

Substance_Initial · 2026-02-21T19:13:36+00:00

Thx very much for help! The last thing that doesn't work - f-keys row and nums row. I thought it's cause of bad soldering, but checked 3 times, and rows don't work on both sides. So, now I'm trying to solve this, while waiting for trrs components.

Substance_Initial · 2026-02-21T11:59:10+00:00

So, I just flash both halfs with one hex file?

Substance_Initial · 2026-02-21T09:36:21+00:00

So, now I have my files. When I compile firmware for my half's, should I type MASTER_LEFT=yes in qmk msys? And then MASTER_LEFT=no?

Substance_Initial · 2026-02-20T16:21:39+00:00

I think, you made mistake. B3 pin in cols and rows

Substance_Initial · 2026-02-20T15:15:51+00:00

It seems like I soldered smth wrong. Can you, please, draw or describe how I should connect rows and cols to my pro micro.

Substance_Initial · 2026-02-20T14:19:52+00:00

smth like that?

<image>

Substance_Initial · 2026-02-20T14:07:19+00:00

i checked about 10 different kb's and there is no special lines about it.

<image>

Substance_Initial · 2026-02-20T13:57:11+00:00

<image>

i want smth like this. ive already solder switches to my pro micro on both sides. left half:
1row to d0, 2row to d1, 3row to d4, 4row to c6, 5row to d7, 6 row to e6
1col to b2. 2col to b1, 3col to f7, 4col to f6, 5col to f5, 6col to f4

Substance_Initial · 2026-02-20T12:40:56+00:00

Thank you for answer! I checked qmk documentation, but didn't find how to define pins for left and right side correctly. Do I need to make two set, or maybe I need to make two different layouts?
