picowalker: recreating the Pokéwalker accessory

picowalker develops an RP2350-based recreation of the Pokéwalker accessory for Pokémon HeartGold and SoulSilver. This repository provides board drivers for the OLED display, IrDA, EEPROM, accelerometer, power management and USB save-data transfer; the application core is separate. Full compatibility with the games remains a goal.
