|
- allow to stay in factory FW by holding a key combo on powerup
|
|
|
|
|
- choose combo
|
|
|
|
|
- document

- test I2C interface using FX2

|
|
- first I2C TX after switch to USER firmware after flashing over I2C fails,
|
2021-06-27 18:45:36 +02:00
|
|
|
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?

|
|
|
- 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)
|
|
|
|
|
- ???
