This is an unofficial firmware, please use at your own discretion.
This is for K8 RGB v1 ANSI.
This fork is intended to bring QMK to the Keychron K8.
Progress:
- QMK custom keymaps are working properly
- RGB works properly, no more flickering
- Bluetooth does not work, currently waiting for QMK to release an official Bluetooth API
- VIA does not work, currently no EEPROM support
Setup repo + dependencies
- Clone this repository: https://github.com/SonixQMK/qmk_firmware
git submodule add https://github.com/SonixQMK/ChibiOS-Contrib.gitmake git-submodule- Copy keyboards/keychron/k8/ from this repository over to your qmk_firmware directory
- You should be able to compile now (
make keychron/k8:defaultin QMK_MSYS terminal)
Instructions on how to flash QMK to the K8:
- Customize your keymap and compile your firmware (
make keychron/k8:default) - Download this flashing tool and run it: https://github.com/qmk/qmk_firmware/files/5862715/SONiX_USB_MCU_ISP_Tool_V2.3.1.7-.zip
- Click 'Load File' and select
SN32F24xBon the right, then choose your *.hex QMK firmware file - VID -
0C45, PID -7040 - Put your K8 into DFU/bootloader mode:
- Remove the spacebar and short the
BOOTpin toP7pin - Note: There are 5 pins on the left of the spacebar switch,
BOOTandP7are the two rightmost pins
- Remove the spacebar and short the
- Connect your K8 to your computer
- Click 'Flash' in the Sonix flashing tool
- Enjoy
- Ability to safely flash bootloader
- Ability to revert to factory firmware
- Confirm Chibios functionality
- Get QMK Working
- Get RGB working
- Get VIA working (currently no EEPROM support, which is required for VIA)
- Bluetooth functionality (currently waiting on official Bluetooth support from QMK)
- Main MCU - HFD2201KBA - appears to be based on/clone of SONIX SN32F24xB
- Bt module CYPRESS CYW20730A2KFBG
- Charge IC - TPU5000
