MechMerlin's DZ60 Keymap

The purpose of this keymap is to provide examples on how to do some common QMK features.

Make example for this keyboard (after setting up your build environment):

make dz60:mechmerlin

Merlin's DZ60 Hardware Info

---

The DZ60 is a 60% pcb produced by KBDFans. It comes in two variants, USB Mini B and USB C. It supports many many layouts. It also supports both backlight and RGB underglow. The USB C variant does not have a hardware reset switch. USB C to C is not supported.

Merlin's DZ60 uses

• Layout B, in QMK this is LAYOUT_60_b_ansi.
• USB C
• 50g Zilents
• Arrows are 78g Zilents
• KPRepublic XD64 Case

Layers

---

Merlin's keymap has three different layers. To switch layers you can use the MO(X) keycode, where X is the layer you want to switch to.

_BL

This is the base layer also known as layer 0. It is a standard QWERTY layout. It has the _FL layer switch key.

_FL

This is the function layer also known as layer 1. It utiizes the following:

• Function Keys
• Navigation Keys
• Audio keys such as Mute, Volume Down and Volume Up.
• _CL layer switch key

_CL

This is the control layer also known as layer 2. It utilizes the following:

• RGB Controls
• RESET key

Non Standard Keycodes

---

RESET

As long BOOTMAGIC_ENABLE is set to yes in rules.mk, the DZ60 can be put into bootloader mode by holding the space key and the b key while plugging in. However sometmes this doesn't work or is troublesome to do, might as well use the RESET keycode to accomplish this.

RSFT_T(KC_SLSH)

Layout B is missing the ? key and is instead replaced with a right shift. This keycode makes it so that the key can be tapped for ? and held for right shift.

LCTL_T(KC_CAPS)

Caps Lock is only ever used by tapping, why not use it as a control key when held? This keycode makes it so that the key can be tapped for caps lock and held for control.

RGB Lighting

---

RGBLIGHT_SLEEP

This is set in mechmerlin/config.h so that when the computer goes to sleep, the RGB lights will also go to sleep on the keyboard. They will turn back on when the computer wakes.

RGB Underglow Color: Yellow

This is set in mechmerlin/keymap.c in the matrix_init_user function. The list of available colors can be found in quantum/rgblight_list.h.
