系统开发逐步使用Rust语言在嵌入式领域Rust也逐步完善本着学习Rust和ESP32的目的搭建了ESP32C3的环境过程中遇到了不少问题予以记录。
ESP-IDF开发ESP32
这一部分可跳过是使用C开发ESP32。直接看Rust 与 ESP32C3
先使用ESP-IDF环境跑一个Hello world
ESP-IDF安装选择v5.1
克隆项目
git clone https://github.com/espressif/esp-idf.git在get-started/hello-world工程中可以编译项目编译前连接开发板可以在设备管理里看到comx这里为com3 使用IDF-CMD命令行进入hello-world目录设置目标
idf.py set-target esp32c3打开配置界面
idf.py menuconfighello-world项目不进行配置编译
idf.py build烧录
idf.py -p PORT flash
idf.py -p COM3 flash烧录成功

克隆代码并进入
git clone https://github.com/esp-rs/std-training.git
cd std-traininghelloboard
连接开发板
进入hardware-check目录
cd intro/hardware-check配置你的wifi名称与密码cfg.toml

espflash monitor创建新项目
为了避免长路径问题将一个空间映射为短路径
subst z: esp32
cd z:由cargo-generate配置新项目
安装
cargo install cargo-generate生成

Initializing a fresh Git repository
✨ Done! New project created z:\hello-world用vscode打开项目
code .加一个死循环
fn main() {// It is necessary to call this function once. Otherwise some patches to the runtime// implemented by esp-idf-sys might not link properly.

}
编译
cargo run一般时间会很长
运行起来
I (356) cpu_start: Starting scheduler.
I (362) hello_world: Hello, world!
I (362) hello_world: loop ...!
I (1362) hello_world: loop ...!
I (2362) hello_world: loop ...!
I (3362) hello_world: loop ...!http客户端
进入espressif-trainnings/intro中的http-client项目
修改wifi配置
编译
cargo run --example http_client完全可以自己写一个服务器提供http服务例如go
package mainimport github.com/gin-gonic/ginfunc main() {engine : gin.Default()engine.GET(/, func(context *gin.Context) {context.JSON(200, gin.H{message: Hello World,})})engine.Run()
}
该服务端提供了get请求默认根目录响应json数据。
在http-client/examples/http_client.rs中 get(http://192.168.83.79/)?;注意需要在一个局域网内并且知道主机的ip地址。
运行
cargo run --example http_clienthttp服务器
提供get服务
编写wifi配置
cd .\http-server\cargo run --example http_server我的开发板获取温度有一些异常注释掉获取温度的代码。
