Ergonomic, split and other weird keyboards

Rules

Keep it ergo

Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)

i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²

¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid

Need help with qmk (lemmy.sdf.org)

Hello everyone, I recently bought a piantor keyboard and I am having trouble with qmk. I have configured two layer keys(num, nav) each of them switches to different layer and I want to be able to hold both of them to access fourth layer(CzechLayer), but I can't seem to figure out how to do it. Here is my keymap.c file:

#include QMK_KEYBOARD_H
#include "keymap_czech.h"

enum layers {
    DefaultLayer,
    NumLayer,
    NavLayer,
    CzechLayer,
};

const uint16_t PROGMEM keymaps[][MATRIX_ROWS][MATRIX_COLS] = {
    [DefaultLayer] = LAYOUT_split_3x6_3(
        KC_PIPE, KC_Q,         KC_W,         KC_E,         KC_R,         KC_T,          KC_Y,    KC_U,         KC_I,         KC_O,         KC_P,            KC_PPLS,
        KC_ESC,  GUI_T(KC_A),  ALT_T(KC_S),  CTL_T(KC_D),  LSFT_T(KC_F), KC_G,          KC_H,    RSFT_T(KC_J), CTL_T(KC_K),  ALT_T(KC_L),  GUI_T(KC_SCLN),  KC_PEQL,

Ideally you want to use QMK's tri_layer feature as I outlined in this comment.

Also you can just use the _______ keycode instead of restating MO(...) on every layer as that is the an alias for KC_TRANSPARENT meaning it maintains the function of the layer below.

For the Piantor you can use beekeeb's ready-to-go firmware from https://docs.beekeeb.com/piantor-keyboard

It's QMK with support for Vial, so you can use the AppImage to define key mappings, layers and many other stuff without having to code and compile QMK. https://get.vial.today

So far that was enough flexibility for me, dodging a compile.

[–] [email protected] 1 points 1 year ago

This. Just copy file that's on GitHub into the keyboard (both sides). The. Start up vial. It's super easy to edit layout that way.

In your num and nav layers you have to change the codes of the opposite layer tap keys. So in your num layer change MO(nav) to MO(chez) and for your num layer change MO(num) to MO(chez). So once you are in either layer hitting to other tap key takes you to your chez layer.

Thank you, it works now

[–] [email protected] 2 points 1 year ago (2 children)

I'm currently assembling my crkbd, looking at the default Configs they do this like so:

  • On layer 0: MO(1) and MO(2)
  • On layer 1: _____ and MO(3)
  • On layer 2: MO(3) and _____
  • On layer 3: _____ and _____

That way regardless of which button you press, if you press two of them you go to a fourth layer.

[–] [email protected] 2 points 1 year ago

This doesn't work perfectly, IIRC if OP presses MO(1), then MO(2), then releases MO(1) it'll stay on layer 3. The better way to do it is defining the layer_state_set_user function and calling update_tri_layer_state as documented here

[–] [email protected] 1 points 1 year ago

That worked perfectly, thanks

I use tapdance to access 4 layouts.

[–] [email protected] 1 points 1 year ago (1 children)

That is a bit too complicated for me, I hardly manage with two layer keys. But thanks

[–] crandel 1 points 1 year ago

It's much easier as you imagine. It always one key and in any layout it works the same. If I need to switch to nums layout I always tap twice. If I hold I switch to chars layout. This is much more intuitive than any key combination
