esp-template

A minimalist template for use with cargo-generate to create no_std applications targeting Espressif's line of SoCs and modules. At present, this template supports the ESP32, ESP32-C2, ESP32-C3,ESP32-C6, ESP32-H2, ESP32-S2, and ESP32-S3; additional devices will be added as they become available.

To generate a project using this template:

cargo generate esp-rs/esp-template

After running the command, there will be a few prompts:

• Project Name: Name of the crate.

• Which MCU to target?: SoC model.

• Configure advanced template options?: If false, skips the rest of the prompts and uses their default value. If true, you will be prompted with:

  • Enable allocations via the esp-alloc crate?: Adds esp-alloc dependency, and initializes the heap.
  • Configure project to support Wokwi simulation with Wokwi VS Code extension?: Adds support for Wokwi simulation using VS Code Wokwi extension.
  • Setup logging using the log crate?: Adds log dependency and initializes logging.
  • Configure project to use Dev Containers (VS Code and GitHub Codespaces)?: Adds support for:
    • VS Code Dev Containers
    • GitHub Codespaces

  Dev Containers also allow flashing from the container using web flash and have the VS Code Wokwi extension already installed.

For a more detailed explanation of the template, see Understanding esp-template chapter of The Rust on ESP Book. If you're seeking a beginner's guide for utilizing no_std (bare metal), consult the Embedded Rust (no_std) on Espressif training.
