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

SPCE061A单片机上LED驱动源程序，包含LED配置显示-the driver source of the LED of the SPCE061A

功能： 1、作为下位机采集8255数据并将此数据通过通讯送出， 2、采集数据为BCD，先转换成二进制，处理后再转换成BCD 3、通讯采用方式3，多机通讯，上位机发地址时TB8=1，其他TB8=0 下位机SM2=1，RB8=1时产生中断后使SM2=0收发数据，结束后SM2=1-Features: 1, as under the 8255-bit machine data collection and communications sent through this data, 2, collected data for the BCD, first converted into binary, and then converted to deal with BCD 3, communication using methods 3, multi-machine communication, PC-fat address TB8 = 1, other TB8 = 0 under the digital machine SM2 = 1, RB8 = 1 when the failure to make SM2 = 0 to send and receive data, after the end of SM2 = 1
