Firmware
--------
- check that the charger's INT pin is high prior to I2C A communication
and return error if it is not (P87 must have pull-up enabled, and
it is low if charger is free to communicate)
- trigger POGO interrupt on P84 (open drain mode)
- implement special key combos:
- Pine + F + H (stay in main FW if pressed during powerup)
- Pine + F + U (enable USB debugger)
- Pine + F + B (jump to USB bootloader)
- first I2C TX after switch to USER firmware after flashing over I2C fails,
subsequent ones work
- also power consumption indicates power consumption of the sotck firmware
so maybe we just sleep in stock instead of switching after flashing?
Userspace input device daemon
-----------------------------
- allow to read keymap config from a file instead of compiling it in
- improve combo key handling
- sticky keys entry mode?
- add various modal modes:
- show modal hints on the display
- write to linux console framebuffer directly
- run a generic process/script (eg. to show mode in i3 status bar)
Modes:
- navigation mode arrows work as arrows without holding Fn key, holding
Fn key inverts the meaning to primary (so Fn+Up types a 'dot')
- sticky Fn mode (all keys act as if Fn is being held)
- sticky keys mode (build a multi-key shortcut gradually, without having to
hold multiple keys at once)
- ???
