30 hours | pcb: Invert button signals | xengineering | |
Making them active-low makes it easier to reset the MCU. For the wipe functionality it does not make a role since it will simply be defined in Devicetree. | |||
31 hours | pcb: Add voltage divider for PCB versioning | xengineering | |
This voltage divider provides an analog voltage between GND and +3.3V to indicate which hardware revision this board is. Thus the same firmware image can be used on multiple PCB versions compensating the hardware differences in software. The resistor combinations are calculated by `tools/resistory_selector.py`. | |||
