單片機(jī)編寫程序，讓LED燈閃爍三次后熄滅？

# include void delay(unsigned inta){ while(a-)} void main(void){ unsignedchariw

單片機(jī)C語(yǔ)言編寫點(diǎn)亮兩盞led燈,首先從中間兩盞點(diǎn)亮,依次相鄰兩盞燈點(diǎn)亮,依次循環(huán)永不停息？

#包括

sbit mp1^0；void延遲符號(hào)(無(wú)符號(hào)字符毫秒)

{

無(wú)符號(hào)int I；

當(dāng)(毫秒)

{

for(i0；我

}

}

主()

{無(wú)符號(hào)字符L

單片機(jī)編程設(shè)計(jì)要求如下：在單片機(jī)的P0口接有8個(gè)發(fā)光二極管作為指示燈，P1.0~P1.3接有4個(gè)按鍵？
