PlatformIO+Zephyr+STM32F756环境搭建及HelloWorld-编程知识

PlatformIO+Zephyr+STM32F756环境搭建及HelloWorld

- 安装VSCode及PlatformIO IDE插件
- 下载示例项目
- ST-Link刷J-link
- 编辑配置文件
- 等待PIO下载依赖及工具链
- 编译下载调试
- Zephyr源码位置

Zephyr作为高质量的开源嵌入式操作系统之一，风头日盛，有比肩FreeRTOS之势，不过貌似内网上介绍PlatformIO+Zephyr+STM32的不多，出个基于PlatformIO的HelloWorld吧，hope it helps~

安装VSCode及PlatformIO IDE插件

PlatformIO IDE插件的下载可能会慢，可能需要梯子，这个因人而异。

下载示例项目

点击PIO插件，在其名为PIO Home的UI，依次点击Home => Project Example => 下拉框选择zephyr-blink（闪灯例子） => import，注意这个默认会下到user目录下，不愿意放C盘的可以自行挪到自己的workspace目录去。在这里插入图片描述

ST-Link刷J-link

我的板子是Nucleo STM32F756，自带ST-Link，习惯刷成J-link

编辑配置文件

打开项目目录下的platformio.ini，注释原有配置并改为如下内容，PIO对ST官方开发板有适配，还是要方便不少，大家依自己情况修改即可。

[env:nucleo_f756zg]
platform = ststm32
board = nucleo_f756zg
framework = zephyrupload_protocol = jlink
debug_tool = jlink

等待PIO下载依赖及工具链

PIO会根据你配置的芯片、平台、板子、操作系统等下载相应的依赖及工具链，耐心等待，这个也是要等一会的，耐心耐心~

编译下载调试

依赖及工具链下载完成之后，点F5，顺利的话出现如下内容，并调用J-link进行下载调试，出现提示记得确认：
