testamatta 011 rev2 matrix issue with keys duplicating output
sadekbaroudi opened this issue · comments
Hi! This is a LOVELY keyboard. I am friends with @yingeling, who introduced me to the board. I think he also requested that you make the rev2 with additional thumb keys.
I built one, and I am running into issues with specific keys. Whenever I type fast, I get duplicate keys. It mostly happens on the E and spacebar keys (I use colemak-dh). There are two pictures below, one of the whole keyboard, and one of the keys that I experience the issue with
My firmware is here:

Do you have any thoughts why this would be happening?
Thank you for reaching out!
However, I don't think I can meet your expectations with my response.
- I only have basic knowledge (as I am neither a programmer nor an engineer).
- I personally have not assembled a Rev2 myself. I just responded to the request because there was a demand for it. Also, I don't know anyone by the name of @yingeling. It was a request from someone else.
- You've made changes to the MCU and added a trackpad, right? That's quite a departure from my original design, and I'm not knowledgeable enough to understand where the potential cause might be.
Even looking at your source, I don't understand half of it. I thought you might have more knowledge than me.
The only simple thing that comes to mind regarding your issue is, 'Could it be that the soldering or traces are short-circuited?' I can't think of anything beyond that.
The firmware I made for Rev2 was just a simple reflection of the changes to the PCB, so I can't deny the possibility of bugs. If you can't overlook that situation, I might consider withdrawing the Rev2-related sources.
Hello @hide-key
Thank you so much for the quick and thoughtful response! I am more than happy to diagnose myself, but the source is not available, which makes it very time consuming. I realize and respect if that you did not open source it, and I appreciate that you did open source the gerbers. If it would be possible to (privately) share the schematics and/or layout files, it would help me diagnose the problem much more easily. I checked for shorts, and I don't have any.
If you would rather not share, I completely understand, but I thought I would ask in case it was a possibility.
You can reach out to me on discord as well! I have a discord server:

Your designs are quite beautiful, I must say :)

Whoops, I tagged the wrong person 😅
