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: 250 uW when idle, 16mW
|
|
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.
