Implement bare-metal (no std library) C++ and Rust system controllers on a resberry pi pico
Embedded systems form the backbone of modern electronics — from IoT to robotics. They operate under tight memory and timing constraints, prioritizing reliability and control over raw convenience. This project develops a stepper motor controller on the Raspberry Pi Pico 2, implemented twice: • Once in C++ using the Raspberry Pi SDK. • Once in Rust using the rp-hal embedded hardware abstraction library.
- 🔹 [Goal 1] — Understand bare-metal programming (no standard library).
- 🔹 [Goal 2] — Learn GPIO, PWM, and interrupt control at the register level
- 🔹 [Goal 3] — Compare safety, readability, and performance between Rust and C++

- Step 1 – Setup: brief description (e.g., initialize repo, install deps)
- Step 2 – Core Functionality: what’s being built and how
- Step 3 – Comparison / Benchmarking: if relevant
- Step 4 – Visualization / Output: how results are displayed or tested
- Step 5 – Deployment / Packaging: optional (web, CLI, hardware, etc.)
