Firmware for an autonomous wave-measurement buoy (ATmega2560-based WII5 v2 board). Reads wave motion from a Sparton AHRS-M1/M2 IMU, samples GPS and battery state, and reports back over Iridium SBD satellite telemetry. Originally developed 2012-2024. This is the first public release. Code, documentation, and field-tested operating modes (Capture, Sleep, Position, ManualTest, SelfTest, LowBattery) are licensed under Apache 2.0 — see LICENSE and NOTICE. See README.md for an overview and build instructions, CONTRIBUTING.md for how to contribute, and DEPLOYMENTS.md for the field-deployment log.
