Summary of Installing Rust for Embedded Development on macOS

This guide provides a step-by-step process for setting up Rust for embedded development on macOS. It covers the installation of necessary tools and configuration for a seamless development experience.

Key Concepts

• Rust: A programming language focused on safety and performance, commonly used for system-level programming and embedded systems.
• Embedded Development: Writing software for hardware that is not a standard computer (like microcontrollers).

Installation Steps

1. Install Homebrew:
   • Homebrew is a package manager for macOS that simplifies the installation of software.
   • To install Homebrew, open the Terminal and run:
2. Install Rust:
   • Use the Rustup tool to install Rust, which manages Rust versions and associated tools.
   • Run the following command in the Terminal:
   • Follow the on-screen instructions to complete the installation.
3. Set Up the Environment:
   • After installation, configure your shell to recognize the Rust toolchain.
   • Add the following line to your shell configuration file (e.g., .bash_profile, .zshrc):
   • Reload your terminal or run source ~/.bash_profile or source ~/.zshrc.
4. Install Target for Embedded Development:
   • To develop for embedded systems, add a specific target (e.g., ARM Cortex-M).
   • For example, to install the thumbv7em-none-eabi target, run:
5. Install Additional Tools:
   • Depending on your project, you might need additional tools like rust-embedded/tools.
   • Install them using:
   • This tool helps in programming and debugging embedded devices.

cargo install probe-rs

rustup target add thumbv7em-none-eabi

export PATH="$HOME/.cargo/bin:$PATH"

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Example Usage

Once everything is set up, you can start a new embedded project by using Cargo, Rust’s package manager:

cargo new my_embedded_project --bin
cd my_embedded_project

After creating the project, you can modify the Cargo.toml file to specify dependencies for embedded development and start coding!

Conclusion

By following these steps, you'll have a Rust development environment set up on macOS, ready for embedded programming. This includes installing Rust, setting up the environment, and adding necessary targets and tools. Happy coding!
