VisualStudioCode嵌入式开发

大多数时候我们使用集成开发环境如： Keil,IAR等进行开发，但随着VSCode的流行，它的简介，丰富的插件，开源免费等优点，让越来越多的嵌入式开发者也转入它的怀抱。 > Visual Studio Code 是由微软开发，同时支持 Windows 、 Linux 和 macOS 等操作系统且开放源代码的代码编辑器，支持测试，并内置了 Git 版本控制功能，同时也具有开发环境功能，例如代码补全、代码片段和代码重构等。[维基百科] > 我们使用VSCode + GNU ARM 工具链可以替代其他嵌入式的IDE。代码编译用 GCC、调试代码用 GDB. **软件工具**： 1. [Visual Studio Code](https://github.com/microsoft/vscode "Visual Studio Code") 2. C/C++ 插件 3. [pyOCD](https://github.com/pyocd/pyOCD "pyOCD") 4.
