A vastly configurable and flexible geomagnetic observatory firmware for the Raspberry Pi Pico (RP2040). Currently supports a variety of sensors that output an analog signal or square wave (eg. FGM3-Plus/Pro). It reads, processes, displays and logs data, lets you configure settings/calibrations at runtime using an intuitive and powerful UI and more.
