除了之前按照原子的驱动写过一个版本，这是通过结构体的编写来实现串口收发
实现功能：
初始化三个串口，调用两个，一个串口发送一个串口接收
串口数据接收除接收数据外还需给出帧有效数据字节长度；
串口可使用USART1、USART2、USART3，串口参数能自由设置；
实现不定长数据帧的串口收发
编译环境：UV5
设计思路及流程
将串口参数，初始化，中断，数组都写在结构体里面，各个模块分开，最后在主函数中进行数组设置，
变量，优先级设置，时钟使能。在循环中设置串口收发来实现功能。比在原子修改思路更加简洁。
1.建立SCOM.c SCOM.h文件
串口初始化结构：
串口参数设置结构体：
中断函数结构：
上述代码主要是判断数据位是否空，然后进行执行
主函数：
数组设置，变量，优先级设置，时钟使能
判断是否小于变量MIAO，小于则代表可以继续接收，然后进入循环。可以3个com口任意调用两个：
Debug模式调试
使用助手调试
至于怎么debug 使用串口助手，请自行百度
