Introduction

pRustIO is a Command-Line Interface (CLI) tool that makes it easier to develop embedded projects using Rust. It can connects the Rust cargo build system with the C/C++ embedded world by automatically linking the Arduino framework to the application.

Core Concepts

pRustIO has two different build modes, depending on what you need for your project:

• Pure Mode (Default): Works completely inside the Rust system using the arduino-hal library. It does not use any extra C or C++ code. This gives you smaller and memory safe applications.
• Hybrid Mode (--hybrid): Sets up your project to use the standard Arduino C++ framework. pRustIO creates a hidden PlatformIO workspace, compiles the C/C++ libraries, and allows you to use Arduino functions (like pinMode and digitalWrite) in your Rust code using the prustio-arduino crate.

Supported Boards

pRustIO supports many popular Arduino and AVR boards. You can see the full list directly from your command line using the tool.
