"qmmk_pro" - custom QMK firmware for Glorious GMMK Pro rev.1

Repository Description

1. You can use the firmware with OpenRGB support to customize colors for each key individually. However, in this case, the lighting settings are stored in the computer's memory. You will need to save the profile file and transfer it to a new device every time. Despite this, the lighting configuration process is straightforward. Another significant advantage is the concise configuration provided by the user.

2. Alternatively, you can manually set all the colors for each key in keymap.c.

• VIA support is available.
• Lighting works without third-party programs running in the background.

• Setting up the colors is more complicated.
• No RGB effects are available.
• Brightness adjustment is not available (please suggest solutions in the comments).

QMK Firmware Compilation

To compile the firmware using the standard qmk_firmware, place the folder qmmk_pro_VIA in:

C:\Users\username\qmk_firmware\keyboards\gmmk\pro\rev1\ansi\keymaps\

QMK Pro for OpenRGB

To compile qmmk_pro_OpenRGB, follow the instructions by ringowu1234 on Reddit.

GMMK Pro Address for OpenRGB

• NAME: GMMK Pro
• USB VID: 320f
• USB PID: 5044

Compilation of Firmware for OpenRGB not Possible from Standard qmk_firmware

Below are the steps I took to enable OpenRGB on my GMMK Pro. As mentioned in many places, I followed this guide for the most part, with some modification after encountering issues. I have no prior coding nor QMK experience. Any suggestions/corrections welcomed.

First, install QMK MSYS from here. Once installation is finished, DO NOT RUN qmk setup. I will explain this later.

Install Git from here.

Then, follow the guide:

Open the QMK-MSYS application and type into the terminal:

git clone https://github.com/qmk/qmk_firmware.git --recurse-submodules
cd qmk_firmware
qmk setup

This will install a file titled QMK-OpenRGB in your user space (unless you change the directory) that will contain all files related to OpenRGB compatible keyboards and will install all submodules.

After this, rename the downloaded file from "QMK-OpenRGB" to "QMK_FIRMWARE" (explanation below).

Continue with the guide. You should have no trouble compiling your own OpenRGB enabled keymap (xxxx.bin). Flash it to the keyboard with qmk_toolbox.

Once flashed, in OpenRGB, open the settings tab, find OpenRGB QMK Protocol, click "add", and fill in:

• NAME: GMMK Pro
• USB VID: 320f
• USB PID: 5044

Hit Save, then restart OpenRGB, click the rescan devices button, and your GMMK Pro should appear.

Changing the file name is the missing step from the original guide, which ultimately fixed the issue for me. I spent hours of trial and error to find the cause:

When you compile the keymap to xxxx.bin, qmk_toolbox will search for files in the "QMK_FIRMWARE" folder, not "QMK-OpenRGB".

Normally, you download the "QMK_FIRMWARE" folder by entering "QMK SETUP" in QMK MSYS. Without this folder, qmk_toolbox will have no target to compile, resulting in error codes.

However, the "QMK_FIRMWARE" folder you get from "QMK SETUP" is the non-OpenRGB version.

Therefore, you have to change the folder name so the "QMK_FIRMWARE" folder contains OpenRGB files.
