23 =2 //使用方法：（此范例自包含，独立于其他程序。）
24 =2 // 1.开头加入#include <reg51.h>语句，一定要有。
25 =2 // 2.初始化串口 InitSerial();//本例中为20MHz晶体，300波特率，模式2初始化
26 =2 // 3.初始化串口缓冲区 InitSerialBuffer();
27 =2 // 4.使用显示字节，字，长字，字符，字符串，清屏函数。
28 =2 //**********************************************************************************
29 =2 //波特率计算公式：
30 =2 // TH1=256-(2^SMOD/32*Fosc/12*1/Bound)
31 =2 // 其中：SMOD=0，1；Fosc=晶体或晶振频率；Bound=波特率
32 =2 // 本例中，SMOD=0；Fosc=20*10E6；Bound=300，所以TH1=0x52。
33 =2 //**********************************************************************************
34 =2 //书写风格：
35 =2 // 1.带yy前缀标志的函数为杨屹改写的等效C库函数。
36 =2 // 2.单个单词用小写，yy定义为前缀，不算一个单词。
37 =2 // 3.多个单词（2个及以上），每个单词首字母大写。(有时变量名第一个单词首字母小写)
38 =2 // 4.采用内缩风格，每次缩进8个空格。
