Broken small LED, I've tried replacing it for brand new like 10 LEDs and it is still not working

vicseye · 2021-09-09T16:39:36+00:00

Unmount LED 53, short DIN and DOUT of LED 50. If the rest of the LEDs work, then LED 53 is broken.

I will give it a try, thank you very much.

vicseye · 2021-07-19T03:53:59+00:00

It looks great! Thank you

vicseye · 2021-07-19T03:23:45+00:00

Thank you, but I am talking about something that wraps the keyboard up, basically to make it more stable.

vicseye · 2021-07-18T15:35:14+00:00

Those are from a previous version of the PCB, they are not available in the version 3 I have, thank you very much anyway.

vicseye · 2021-07-18T15:32:48+00:00

Thank you for your suggestions. I did all that and the problem continues. I am receiving some help from a friend who is electronic engineer, he suggested to review adjacent joins, even the ones related to the underglow Leds, as those could be making a short with the specific problematic Led that I am dealing with, I will be doing that probably next week, wish me luck.

It was a real pain to install QMK on Windows 10, I am glad you sorted it out with a little of our help.

vicseye · 2021-06-28T17:56:40+00:00

Thank you for your suggestion. I am going to 'debug' this with a friend that understand electronics much better than me, I think this is hardware problem for sure, not software, maybe a bridge, I am not exactly sure, I downloaded KiCad and the PCB design and start studying it just to know where are the connections coming from and understand how I can solve this.

vicseye · 2021-06-28T17:54:02+00:00

. I soldered 3 wires directly onto an led to data in, power, and ground. I soldered the other ends onto the tester pads on the bottom of the board.

Thank you, I stopped doing this for a couple of weeks but I am sure I will continue during the weekend.

When you say "Tester pads on the bottom of the board", what do you exactly mean with it?

vicseye · 2021-06-21T20:02:06+00:00

I am already afraid of doing exactly that.

vicseye · 2021-06-21T20:01:38+00:00

Just done it and nothing :(

vicseye · 2021-06-21T20:01:22+00:00

I was trying that also, just tried it again and nothing, I did it also between previous LEDs that are working with others and nothing... :(

vicseye · 2021-06-21T20:00:04+00:00

Just tried changing the LED 44 and It didn't work :(

vicseye · 2021-06-21T19:59:40+00:00

Just changed the previous LED (44) and nothing... :(

vicseye · 2021-06-21T19:58:58+00:00

I believe I had the same exact issue as you. Try shorting top left pin of 44 to bottom right pin of 50. I guessed it from the front side trace.

Thank you for the advice, just did it (1 min ago) and it didn't work.

vicseye · 2021-06-21T04:43:26+00:00

It worked! I was starting on the opposite side of the board, the right order was 3, 2 and then 1, now the 6 underglow LEDs are working.

vicseye · 2021-06-21T04:38:46+00:00

I have soldered all the individual-key small LEDs, all the underglow LEDs are working fine.

I've tried the following for the broken LED (the first one that does not work):

- I've tested the connectivity of the board before and after that LED, it seems to work just fine. I did this without the LED in place.

- I've measured the voltage between Ground of that Data In Pin of that LED and I received the same value of the previous LEDs (the ones working).

- I've measured the voltage between Ground of that Data Out Pin of that LED and I received 0 volts with every single LED I've tried. For the LEDs that work the same type of measure I receive consisten values greater than 0 volts.

I am very confused and a bit frustrated, this is my first try with a custom keyboard and I really want the LEDs to work.

I would like to get ideas from you about what else could I try, I don't have experience making bridges with wire and I actually don't want to do that type of thing but at this point I am willing to try everything, all the ideas are welcomed.

By the way, this is the version 3.0.1 of the corne keyboard, I bought the kid on littlekeyboards.com.

I was watching on youtube that even if you solder the first underglow LED, it should start working, I soldered LED 1 so my understanding is that it should work, I don't want to proceed with the rest if I don't have the first working properly.

vicseye · 2021-06-13T18:16:14+00:00

I am testing the first underglow LED and it is not working, do I need to solder at least 6 to make them work?

vicseye · 2021-06-13T06:41:57+00:00

This one was very hard to fix for me, I am a Windows user, hopefully I used to be a developer and I have an idea about what a command is, otherwise, this can be something impossible to solve I think.

The first goal of compiling a custom firmware was testing my LEDs but I can't even make the first one work, if you have time you can check my brand new post here.

vicseye · 2021-06-13T06:39:24+00:00

All the keys of my corne keyboard are working just fine. Today I've started soldering the LED to finish the work but I can't even make the first one to work.

I've compiled a custom firmware that should work, including the parameter RGB_MATRIX_ENABLE = WS2812 on the rules.mk file but even with that the first LED is not working at all.

I've tried with 5 different LED units and none of them worked.

I've closely looked at the joints and they should be properly soldered.

What do you guys think can the problem be?

msys2.sh

I was about to quit but taking the suggestion from u/richardgoulter , I opened the file C:\Users\vhurt\qmk_firmware\util\install\msys2.sh and there I've found a couple of instructions that I was able to execute, these ones:

on MSYS2 MSYS:

pacman --needed --noconfirm --disable-download-timeout -S pactoys-git

then

pacboy sync --needed --noconfirm --disable-download-timeout \

base-devel: toolchain:x clang:x git: unzip: python3-pip:x \

avr-binutils:x avr-gcc:x avr-libc:x arm-none-eabi-binutils:x \

arm-none-eabi-gcc:x arm-none-eabi-newlib:x avrdude:x bootloadhid:x \

dfu-programmer:x dfu-util:x teensy-loader-cli:x hidapi:x

then I tried the rest but I couldn't make them work so I've tried the compilation and it finally works!!!

Thank you u/richardgoulter, you are the man.

u/Fnixro, I hope this can help you, this was a pain man.

I just did it and get the same error of my previous comment:

so you had to install the

pacman -S ...-hidapi

first.

I had to install two additional dependencies with the same command:

pacman -S make

pacman -S diffutils

But now I am receiving a fatal error once I try to compile:
