# esp32

Rust with Xtensa support for Nix using flakes.

```

$ nix flake show github:knarkzel/esp32

└───packages

    └───x86_64-linux

        └───esp32: package 'esp32'

$ nix build github:knarkzel/esp32#esp32

$ ls -a result

.  ..  .cargo  .rustup

```

## Minimal example

```nix

{

  inputs = {

    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";

    esp32 = {

      url = "github:knarkzel/esp32";

      inputs.nixpkgs.follows = "nixpkgs";

    };

  };

  outputs = {

    self,

    nixpkgs,

    esp32,

  }: let

    pkgs = import nixpkgs {system = "x86_64-linux";};

    idf-rust = esp32.packages.x86_64-linux.esp32;

  in {

    devShells.x86_64-linux.default = pkgs.mkShell {

      buildInputs = [

        idf-rust

      ];

      shellHook = ''

        export PATH="${idf-rust}/.rustup/toolchains/esp/bin:$PATH"

        export RUST_SRC_PATH="$(rustc --print sysroot)/lib/rustlib/src/rust/src"

      '';

    };

  };

}

```

## Getting started

Use the above flake, then follow the [Rust on ESP Book](https://esp-rs.github.io/book/writing-your-own-application/generate-project-from-template.html).

## Notes

When building from source, you need a huge amount of memory, about 36 GB.

To create temporary swap, use following commands:

```

$ fallocate -l 36G /tmp/swap; mkswap /tmp/swap; swapon /tmp/swap

```
