此程序用于DS1802,LCD1602,AT89S51系列 组成的温度显示小系统，程序是我参加机电设计大赛时的一个参考程序，改一改就可以用了（只要把L1与L2的数据改动一下，就能在LCD上显示不同的字符）。-This procedure for the DS1802, LCD1602, AT89S51 series consisting of the temperature shows a small system, the program that I participated in the Electrical and Mechanical Design Competition at the time of a reference procedure can be used simply (as long as the L1 and L2 data changed on the LCD can display different characters).
