Vial is an open-source cross-platform (Windows, Linux, Mac and Web) GUI software for configuring QMK keyboard in real time.
We made Vial-compatible QMK firmwares in July 2022.
If the keyboard was bought before July 2022, please download above firmware and QMK Toolbox. Follow the tutorial videos to flash the firmware.
(Note: When you update the Knight Plus numpad firmware, the USB cable should be plugged into the numpad and the corresponding numpad firmware should be used.)
