拿到一块新的开发板，一般从点灯开始，那么第一次上手这个开发板也从LED点灯开始。

一、准备条件

硬件：

<ul yne-block-type="list">
<li>一块STM32U5A5ZJ开发板；</li>
<li>一根USB Micro-Type-线；</li>
<li>一台装有STM32CubeMX和STM32CubeIDE的电脑；</li>
</ul>

文档：

STM32CubeMX、STM32CubeIDE使用指南

二、工程建立

STM32CubeMX和STM32CubeIDE的安装就不介绍了，网上有很多。

1、打开STM32CubeMX，搜索MCU型号，开始工程

 

选中不带TrustZone的项目

 

2、配置时钟

1）配置晶振

  

2）配置时钟



3、配置LED

查看原理图LED灯控制引脚为PC7，低电平点亮。



在STM32CubeMX搜索PC7，可以看到它为定时器3通道2，所以需要配置定时3通道2为PWM模式；

  

3、配置定时器

使能定时器3，通道2

  

设置定时3通道2参数

  

4、使能icache和SMPS

1)使能ICACHE

  

2）配置SMPS

  

不配置这两项产生工程时会提示警告

5、配置与产生工程

 

6、编译

  

7、下载验证

3673a48ba8c5b6ba494d95269897719a

工程如下：

<div></div>

 
</article>
</div><script> var loginstr = '<div class="locked">查看本帖全部内容，请<a href="javascript:;" style="color:#e60000" class="loginf">登录</a>或者<a href="https://bbs.eeworld.com.cn/member.php?mod=register_eeworld.php&action=wechat" style="color:#e60000" target="_blank">注册</a></div>';

if(parseInt(discuz_uid)==0){
(function($){
var postHeight = getTextHeight(400);
$(".showpostmsg").html($(".showpostmsg").html());
$(".showpostmsg").after(loginstr);
$(".showpostmsg").css({height:postHeight,overflow:"hidden"});
})(jQuery);
} </script><script type="text/javascript">(function(d,c){var a=d.createElement("script"),m=d.getElementsByTagName("script"),eewurl="//counter.eeworld.com.cn/pv/count/";a.src=eewurl+c;m.parentNode.insertBefore(a,m)})(document,523)</script>

拿到一块新的开发板，一般从点灯开始，那么第一次上手这个开发板也从LED点灯开始。而且还是PWM灯，高级高级！

大佬，更高级，上手就是移植LVGL<img height="48" src="https://bbs.eeworld.com.cn/static/editor/plugins/hkemoji/sticker/facebook/congra.gif" width="48" />
