Keychron keyboards custom build instructions
Response (or dynamic) backlight modes are switched off in stock firmware.
You'll need qmk CLI and git.
Install toolchain
brew install git qmk/qmk/qmk
Clone Keychron QMK repo in ~/qmk_firmware
cd ~
git clone https://github.com/Keychron/qmk_firmware.git
Switch to playground branch
cd qmk_firmware
git branch playground
cd ..
Init QMK
qmk setup
It will give you the warning about not official repository being used, it's OK since we'll use Keychron fork.
Navigate to corresponding keyboard model folder
cd qmk_firmware/keyboards/keychron/q1/q1_ansi_stm32l432_ec11
It's Q1 V2 (stm32l432) ANSI Knob (ec11) version. TODO: add description for more variants.
Edit firmware config using your favourite editor
$EDITOR ../config.h
You may uncomment any effects you would like to have. Responsive effects have _SOLID_ in their names.
Note that RGB_MATRIX_FRAMEBUFFER_EFFECTS should also be enabled.
That's it, it is time to compile the source
qmk compile -km keychron
Resulting firmware lays in ~/qmk_firmware with the name like keychron_q1_q1_ansi_stm32l432_ec11_via.hex
As recommended using QMK Toolbox. See official Keychron instruction for details https://www.keychron.com/blogs/archived/how-to-reset-your-keychron-q1-to-factory-settings
