TODO
----
- Lipo charger configuration: fast charge time
- Lipo voltage ADC sensing
- Lipo charger configuration: fast charge time: USB charger spec?
- Low voltage alarm: LED indcates voltage of Lipo
- CTS/RTS lines are needed? just connect in loop back if no flow control is needed.
- CTS is needed for waking up from deep sleep?
- Serial API callback when data are available/received(and when send buffer is available)
- Serial API instance several serial ports can be used
- DCDC converter: squeaky inducter with onsemi NCP1402
- Lipo charger MCP73831: needs capacitor 4.7uF *2
- Keymap layer bug: during space is pressed(mousekey) press Fn(HHKB) then release space before Fn, in result HHKB layer is locked(toggled) unintentionally.
DONE:
- USB connection check - 07.01
@ -17,6 +21,7 @@ DONE:
- USB/BT switching BT is on -> BT, BT is off -> USB - 07.01
- Under voltage lock out UVLO for protection of Lipo - Lipo has discharge protection at 3.100V 07.01
- Power saving: HHKB scan, BT radio control - 9h with 850mAh, this is enough 07.01
- Power selector doesn't work; Q4 MOSFET leaks from Lipo to USB power line. -- use Schottky instead 07/04
