Goji Keyboard with low-profile keycaps mounted

Goji keyboard, MX style switch edition (with PBT keycaps)

@eudes Gracias!

[Matias N. @protobits]

Had to put training wheels on.
The non staggered layout is killing me. I'm realizing my brain has it hardwired.

Also made a simple case for testing.

[Matias N. @protobits]

I just found a letter in my beard

[Matias N. @protobits]

@eudes Yeah, I will probably do that. But I'm not yet capable of typing a ~ yet either 😅
Do you speak spanish?

[Matias N. @protobits]

@eudes The other issue is language support, as it changes where symbols actually are w.r.t. underlying keymap. I only need support for "ñ" though, which I could map to some key combo. In that case I could leave other keys unchanged (and use US layout)

[Matias N. @protobits]

@eudes Yeah, I could see how while practicing I got a bit better at it.
It is a cool exercise on brain plasticity 😅

[Matias N. @protobits]

A bit tidier now. TRS jacks and cable to arrive soon.
Now on to learn how to type on this thing 😅

[Matias N. @protobits]

Now it *fully lives*!
Halves intercommunicating via single-wire (one-way) UART using PIO and DMA

[Matias N. @protobits]

@btashton Cool, thanks!

[Matias N. @protobits]

alllllmost there...

[Matias N. @protobits]

It lives! (one half, at least)

[Matias N. @protobits]

Of course once I loose hope of finding the bug, I find it.
Yay, USB is functional 😁
I think the rest should be more straightforward. Hopefully I can soon type on this thing.

[Matias N. @protobits]

Anyone with a USB analyzer and a raspberry pico would like to help?
Right after enumeration, the host disconnects the device. Wireshark does not give much insight to know why.😑
This will help getting ZMK functional on the pico, and thus any keen based on it.

@acassis Trying to support RP2040 USB on ZMK (Zephyr) to get the Goji keyboard functional

[Matias N. @protobits]

@SipeedIO How is it wired to the MCU controlling it? Is it a flex PCB to the main keyboard PCB?

[Matias N. @protobits]

Firmware for the keyboard while take some time as the Pico is relatively new among keyboard firmware. KMK is a bit messy to work with. QMK and ZMK have no real Pico support yet.
I got ZMK working on the Pico (can read the keys) but it needs writing USB and wired split support.

[Matias N. @protobits]

@MLE_Online That sounds really cool, like vintage sci-fi stuff. Made me think of this for some reason

Vaccinated! 😁😁😁
