FOSS firmware for pinephone keyboard ==================================== Features: - Dual firmware architecture: stock firmware + optional user firmware. - Stock firmware implements the full functionality of the keyboard. - Stock firmware is layout independent, it reports the raw status of the whole keyboard matrix. - Key maps and combinations can be arbitrarily changed in the keyboard driver without re-flashing the firmware. - Stock firmware should be sufficient for most users who will not want to do HW modifications to their keyboard to add more peripherals to the keyboard MCU. - Power efficient implementation using power-down feature of the MCU to save power as much as possible. (currently: 9 mW when idle, 20mW in active scanning mode - with at least one key pressed) - Stock firmware is flashed in factory and allows flashing user firmware from the pinephone itself over I2C interface. - User firmware can be used either for updates or for customizations (SW support for HW modifications of the keyboard) - USB stack and tools for stock firmware flashing using ELAN's original bootloader to ease development of the stock firmware. - Self-testing features to quickly test for issues with the keyboard matrix. - Fully based on FOSS software, with no dependencies. You only need sdcc 4.1+ to build the firmware. See demo video https://megous.com/dl/tmp/kb.mp4 and some technical overview https://xnux.eu/log/ You can support the project via donations at https://xnux.eu/contribute.html#toc-donations See also Samuel's kernel driver: https://github.com/smaeul/linux/commits/wip/pp-keyboard Enjoy! ~megi
