【STM32F411Nucleo测评】开箱，搭建开发环境，串口输出 [复制链接]

> 当时申请了年终回炉的Nucleo-F411板子，申请的是年后发货，春节物流速度慢到龟速，现在终于收到了板子，开始玩耍。

### 开箱

这次申请的是Nucleo-F411的板子，最高100MHz主频，512KB Flash和128KB RAM，外设资源也比较丰富

拿出板卡

<ignore_js_op>

<a href="javascript:;" onclick="showWindow(this.id, this.getAttribute('url'), 'get', 0);" id="savephoto_790022" url="home.php?mod=spacecp&ac=album&op=saveforumphoto&aid=790022&handlekey=savephoto_790022">保存到相册</a>

Nucleo的白色板子看着还是挺顺眼的

<a href="javascript:;" onclick="showWindow(this.id, this.getAttribute('url'), 'get', 0);" id="savephoto_790016" url="home.php?mod=spacecp&ac=album&op=saveforumphoto&aid=790016&handlekey=savephoto_790016">保存到相册</a>

</p>

### 资料获取

STM32 的资料就不用多说了，直接找到官方的原理图，用 CubeMX 配置就可以，找到原理图看下调试串口的管脚是PA2和PA3，用cubemx初始化一下SWD调试口、外部晶振和这两个串口管脚。

生成Keil工程，然后加段循环打印输出hello world的代码

```
HAL_Delay(500);
HAL_UART_Transmit(&huart2, "hello world\r\n", 13, 0xffff);
```

编译程序，通过板载的STlink下载到板子上，打开设备管理看到STLink2.1的虚拟串口是COM4

<ignore_js_op>

<div class="tip tip_4 aimg_tip" id="aimg_790019_menu" style="position: absolute; display: none" disautofocus="true">
<div class="xs0">
