VScode+ESP32-IDF的使用

1.简介

Visual Studio Code (简称 VSCode / VSC) 是一款免费开源的现代化轻量级代码编辑器，支持几乎所有主流的开发语言的语法高亮、智能代码补全、自定义热键、括号匹配、代码片段、代码对比 Diff、Git 等特性，支持插件扩展，并针对网页开发和云端应用开发做了优化。软件跨平台支持 Win、Mac 以及 Linux，运行流畅，可谓是微软的良心之作……

话说微软 VSCode 的发展势头简直超猛！！经过多年发展后，目前已成为全球开发者最喜爱也是最热门的主流代码编辑器之一了！在很多年前，大家都没想过有一天能在不用虚拟机的情况下，直接能在 Mac、Linux 上运行使用到微软的 Visual Studio 或像 VSCode 一样的免费却又强大的开发工具吧。VSCode非常好用，乐鑫芯片公司为了让用户使用VScode IDE工具，开发了对应的ESP-IDF插件。

ESP-IDF 是乐鑫官方的物联网开发框架，也是最基础的开发框架，其他的框架，例如音频开发框架 ESP-ADF 也是基于 ESP-IDF 的，所以说 ESP-IDF 框架是学习乐鑫 ESP32 系列芯片开发绕不过去的一道坎。

2.安装VScode和Esp32-IDF插件

2.1 VScode 安装较简单，下载完安装即可。

2.2 在插件管理界面搜索esp32 ，安装Espressif IPF

2.3 选择EXPRESS 安装IDF和IPF TOOLS、 Python环境

2.4 选择安装的路径和版本，选择国内Espressif git服务器

2.5 等待安装

注意：如果下载中断，需要你手动删除你安装目录下的.espressif 和 esp。然后重新安装

报错： EPERM: operation not permitted, rename 'F:\Code\vsCode_env\esp32_IDF\esp-idf-v5.0.1' -> 'F:\Code

EBUSY: resource busy or locked, rename 'F:\Code\vsCode_env\esp32\esp-idf-v5.0.1' -> 'F:\Code\vsCode_env\esp32\esp-idf'

工作区的问题，工作区设置到了F:\Code\vsCode_env\esp32_IDF ，应修改为其他区域。

3.测试安装的IPF-TOOL

3.1 创建一个自己的目录，将hello word工程拷贝过去

3.2 打开helloword并编译链接

	使用的串口
	选择目标芯片
	Menuconfig
	清理工程
	编译工程
	下载程序的方式
	下载

4.综述

VSCode+ESP32 编译过程，其实是调用了开源的cmake ninja。建议多学习下cmake,ninja ，这对学习操作系统非常有帮助（鸿蒙也是用的ninja+cmake)

出现乱码问题：

工具的默认编码和程序输出的“汉字”编码不一致导致。

=======以下方法仅供参考，会导致KEIL MDK 中汉字乱码======

Powershell 使用GBK

CMD 使用
