使用 PlatformIO 与 Nix 搭建 ESP32 项目
使用 PlatformIO 与 Nix 搭建 ESP32 项目的简要说明
- #nix
- #esp32
- #platformio
- #embedded

使用 Nix 初始化项目
terminal
mkdir -p ~/test/esp32cd ~/test/esp32nix flake init为 Nix 配置开发环境
- 编辑项目中的
`flake.nix`文件。以下是我个人项目中使用的示例。
NIX1{2 description = "ESP32 + PlatformIO devshell";3 inputs = {4 nixpkgs.url = "github:nixos/nixpkgs?ref=nixos-unstable";5 };6 outputs = {7 self,8 nixpkgs,9 }: let10 system = "x86_64-linux";11 pkgs = import nixpkgs {inherit system;};12 in {13 devShells.${system}.default = pkgs.mkShell {14 packages = with pkgs; [15 platformio16 python317 gcc18 gnumake19 pkg-config20 picocom21 clang-tools # this for my setup lsp and formatter22 ];23 shellHook = ''24 if [ -z "$ZSH_VERSION" ]; then25 export SHELL=${pkgs.zsh}/bin/zsh26 exec ${pkgs.zsh}/bin/zsh -l27 fi28 '';29 };30 };31}1{2 description = "ESP32 + PlatformIO devshell";3 inputs = {4 nixpkgs.url = "github:nixos/nixpkgs?ref=nixos-unstable";5 };6 outputs = {7 self,8 nixpkgs,9 }: let10 system = "x86_64-linux";11 pkgs = import nixpkgs {inherit system;};12 in {13 devShells.${system}.default = pkgs.mkShell {14 packages = with pkgs; [15 platformio16 python317 gcc18 gnumake19 pkg-config20 picocom21 clang-tools # this for my setup lsp and formatter22 ];23 shellHook = ''24 if [ -z "$ZSH_VERSION" ]; then25 export SHELL=${pkgs.zsh}/bin/zsh26 exec ${pkgs.zsh}/bin/zsh -l27 fi28 '';29 };30 };31}- 在项目目录中执行
`nix develop`。
使用 PlatformIO 初始化项目
- 使用
`arduino`框架时：
terminal
pio project init --board esp32dev --project-option "framework=arduino"- 使用
`espidf`框架时：
terminal
pio project init --board esp32dev --project-option "framework=espidf"编译项目
terminal
pio run -t compiledb配置 clangd 以减少 LSP 报错
- 在项目根目录创建
`.clangd`文件。

- 运行 / 烧录 / 监视项目。
terminal
pio run # run projectpio run -t upload # upload projectpio device monitor # monitor device- 为项目安装库。可通过命令安装，或在执行
`pio lib install`后在`platformio.ini`中声明依赖。
terminal
pio lib install <LIB_NAME>INI
