Firmware
--------
2021-08-02 10:11:44 +02:00
- allow to stay in factory FW by holding a key combo on powerup
- choose combo
- document
2021-08-02 10:11:44 +02:00
- test I2C interface using FX2
2021-08-02 10:11:44 +02:00
- 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?
2021-08-02 10:11:44 +02:00
------------
2021-08-02 10:11:44 +02:00
- implement I2C configuration options
- disable keyboard matrix scanning
- only enable USB in stock FW upon request over I2C (idling USB stack takes
about 0.6mA on top of 1.8mA baseline)
Charger behavior
----------------
- does the charger turn off VOUT after some period of low load?
- does it enable it again to see if there's a need for it?
- this auto-off behavior will kill the power to the keyboard
controller, so we need a way to detect it and power the controller
from the pinephone side by enabling VBUS.
- tricky!
- or make the user keep pressing the kb power button to use the
keyboard for a while, like in a train conductor has to in a train :)
- not good!

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)
- ???
