<p>第四课、USB不停电下载</p>
<p><font color="red">注：前提是要把USB不停电功能代码增加到程序中烧写后可实现USB不停电下载</font></p>
<p>1、看了演示马上工具测试发现不行，原来是要增加功能代码到工程程序中才能实现</p>
<p><img src="data/attachment/forum/202412/20/134107jlg5ujjijtzmptuj.png" alt="image.png" title="image.png" /></p>
<p>2、实战开发</p>
<p>准备步骤如下：下载USB库文件，移植二个文件（头文件 、lib库文件）到工程目录</p>

第八课，定时器周期性调度任务
根据课程来实战完成任务，这课开始感觉有点难度了，自己写了一边代码下载后发现与设想的运行不一致。检查发现是计数变量到设定值时没置0，要等好一会也会正常闪烁，应该是溢出了。

还有一个按键的判断原先是20ms延迟，现在变量计量有点不适应和理解。
实战任务练习1

关键代码定时器及三个计数变量


判断计数变量到指定值时置0，LED取反，即可完成任务1

也可以如下代码


任务2


关键代码 LED是数组，i是取数组第几个元素，count_ms 1ms 累加

500ms 进行LED控制


任务3

任务3 关键代码，定时器及变量定义

串口输出和按键数组移动


如上任务代码已在开发板测试通过，如有错如请指出。

结构体数组的周期性任务调度


这个有点难，还没有形成这样的思维方式，看代码学习略过
