8051进行8路LED模拟分支控制
用8051的P1口作为输入、P0口作为输出，通过74LS244接8路LED模拟分支控制。
P1.0为低电平时，点亮一LED；P1.0为高电平、P1.1为低电平时点亮全部LED；当P1.0、P1.1都为高电平时，LED按四个一组，轮流反复点亮 P1.0、P1.1、P1.2都为高电平时，8LED逐一点亮并反复循环

P1.0 for low-level, a lit LED; P1.0 for margin, P1.1 for low-level when all the LED lights; When P1.0 and P1.1 for margin, LED by a group of four take turns repeatedly lit P1.0, P1.1, pesticides for margin, 8LED lit one by one and repeatedly cycle
