单片机的Demo，可以在单片机上演奏音乐 用汇编语言的写的

红外遥控接收 ORG 0000H LJMP START 转入主程序 ORG 0010H START: MAIN: JNB P2.2,IR LJMP MAIN 以下为进入P3.2脚外部中断子程序，也就是解码程序 IR: MOV R6,#9 SB: ACALL DELAY882 调用882微秒延时子程序 JB P2.2,EXIT 延时882微秒后判断P3.2脚是否出现高电平如果有就退出解码程序 DJNZ R6, SB 重复10次，目的是检测在8820微秒内如果出现高电-infrared remote control receiver ORG 0000H LJMP START into main program ORG 0010H START : MAIN : JNB P2.2, IR LJMP MAIN below to enter P3.2 foot external interrupt subroutine, which is decoding procedures IR : MOV R6, SB# 9 : Calling ACALL DELAY882 882 microsecond delay subroutine JB P2.2, EXIT 882 microsecond delay after the judgment whether there P3.2 feet to I quit if decoding procedures DJNZ R6, SB repeated 10 times, the purpose is to test if within 8,820 microsecond high

实现多个数字滚动，移位显示，当按下某个按键时，会将对应于端口的数值送入低位数码管显示-To achieve more than the number of rolling, shift display

基于ds12c887的电子时钟的C语言程序-Based on the electronic clock ds12c887 the C Language Program
