五種編程方式實(shí)現(xiàn)流水燈的單片機(jī)c程序

1、五種編程方式實(shí)現(xiàn)流水燈的單片機(jī)C程序功能：采用順序結(jié)構(gòu)實(shí)現(xiàn)的流水燈控制程序此方式中采用的是字操作（也稱為總線操作）#includevoiddelay(unsignedi)延時(shí)函數(shù)聲明voidmain()主函數(shù)while(1)P1=0xfe點(diǎn)亮第1個(gè)發(fā)光二極管0.000389sdelay(200)延時(shí)P1=0xfd點(diǎn)亮第2個(gè)發(fā)光二極管0.155403s0.1558delay(200)延時(shí)P1=0xfb點(diǎn)亮第3個(gè)發(fā)光二極管delay(200
