前言

这道A测题目老师在文档中已经给出了大部分代码，（不过是图片），我已经把代码，仿真电路都整理完毕，这篇文章主要帮助大家配置环境以及更换自己学号相关联的温度阈值。
祝大家毕业顺利！

一、Keil5的安装

1.获取安装包

首先你需要一个Keil5的安装包百度云连接：https://pan.baidu.com/s/1VwdItEH7FZ58tju6Zy24tw?pwd=0mo9
提取码： 0mo9

2.安装Keil5

上述链接中，有两个文件，先运行Keil_uVision_MDK522.EXE，一切按照默认进行，老师发的文件好像也有一个安装包，两个都可以使用，按照老师的教程可以完成此步骤。
看这个也行：Matcha_ice_cream的博客

3.运行注册机

见2中的链接博客。

4.安装器件库

老师源文件的器材库不太对火，我重新搞了一个，链接如下：
百度网盘链接：https://pan.baidu.com/s/1NzUNPwm7iMLjvIi2aNITPQ?pwd=s51v
提取码 s51v，
内含两个器件库，一个ARM的，一个STM32F的。直接双击就可以安装。
我们的实验是在STM32F103C6上进行的，故而需要我发送的第二个库。

至此，keil5安装完成。

二，运行工程文件，获取HEX可执行文件

1，获取工程文件

完整的工程文件链接如下：基于stm32f103芯片的直流电机驱动控制仿真系统工程文件全套

其中main函数如下：其实你仅需要将老师的工程文件中的main函数做一个替换。（如果你跑不起来，可以参考上面的文件）
