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:

```bash
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][no_std-training] training.
