Tip:

​	1.根据stm32cubeMX中时钟树和定时器序号，确定定时器输入时钟频率

2.部分频率不能恰好一样，会存在一定的误差

```
这是因为寄存器不能整除导致的，当频率越来越大，这个误差就会越来越大。
```

## 程序执行异常

### vcruntime140.dll was not found

解决方案:

下载Visual C++ Redistributable库文件，安装即可

[Latest supported Visual C++ Redistributable downloads | Microsoft Docs](https://docs.microsoft.com/en-US/cpp/windows/latest-supported-vc-redist?view=msvc-170)

错误分析

```
vcruntime140.dll，是vc工程编译出来的程序必须依赖的库，如果没有则需要安装相应的库包。
```



### vcruntime140d.dll was not found

![image-20220618173238145](markdown.assets/README.assets/image-20220618173238145.png)

```
vcruntime140d.dll 是 vcruntime140.dll的包含Debug信息的版本,如下图在viso编译时，生成的目标选择Debug版本，则连接的是vcruntime140d.dll，如果是Release连接的是vcruntime140.dll，如果想要安装vcruntime140d.dll，安装驱动库即可。
```
