Webb14 okt. 2016 · Re: Override GPIO state at boot. The safest (and easiest) way to get a known pin state from power-on is to choose pins which naturally have the correct pull state - work with the system, not against it. By default, GPIOs 0-8 pull high, and GPIOs 9-27 pull low. You can always add an external inverter if you need to. Webbmicro:bit pins.
