Feb 1, 2025February 2025 monthly summary for Cyclone-Robosub/Propulsion_2024_CPP: Delivered foundational GPIO portability and improved numerical stability in physics simulations. Implemented a GPIO Abstraction Layer (WiringControl wrapper) to encapsulate GPIO interactions, added multi-platform GPIO support via Pico SDK groundwork, and included a mock backend for non-RPi testing along with PWM helper enhancements. Stabilized build hygiene by addressing namespace and include issues and by improving generalized error messaging. Began Pico SDK integration work (under active development; some issues being tracked). In physics, resolved precision losses by migrating calculations from float to double and standardizing abs usage, improving simulation accuracy. These changes provide cross-platform hardware portability, more reliable simulations, and a solid base for future Pico-enabled deployments.
