Firmware Firmware
-------- --------
- implement I2C configuration options - allow to stay in factory FW by holding a key combo on powerup
- disable keyboard matrix scanning - choose combo
- document
- only enable USB in stock FW upon request over I2C (idling USB stack takes - test I2C interface using FX2
about 0.6mA on top of 1.8mA baseline)
- first I2C TX after switch to USER firmware after flasging over I2C fails, - first I2C TX after switch to USER firmware after flashing over I2C fails,
subsequent ones work subsequent ones work
- also power consumption indicates power consumption of the sotck firmware - also power consumption indicates power consumption of the sotck firmware
so maybe we just sleep in stock instead of switching after flashing? so maybe we just sleep in stock instead of switching after flashing?
- power measurement / optimization ------------
- currently with no USB stack and in constant PD mode: 1.8mA
- theoretical lower limit 0.5mA (no idea how they achieve it)
