用C语言编写,单片机控制LED灯并用定时器延时,每隔一秒使LED依次点亮,8 个灯
提问者采纳
每隔一秒使LED依次点亮’,其实我没看懂这句话。是每隔一秒亮一个灯。,还是。
每隔一秒亮一个灯,亮完8个灯就停止,不亮了
二楼那个就是了呀
C语言编写的有没有啊
#include&reg52.h&#include&intrins.h&#define uchar unsigned char#define uint unsigned intuchar a=0,i=8;void main(){
//初始化定时器0 TH0=()/256;
//设定50ms计时初值 TL0=()%256; EA=1;
//开总中断 ET0=1;
//开T0中断 TR0=1;
//启动T0定时器
t=0X P1=t; while(i) {
t=_crol_(t,1);
} } while(1) P1=0
//8个led灯为共阳接法}void time0() interrupt 1{
TH0=()/256;
//设定50ms计时初值 TL0=()%256; a++;}

/&#47!几句话的事;
/开T0中断 TR0=1; EA=1!;/定时器重新赋值就可以了
TL0=0xb0;设定50ms计时初值 TL0=0xb0;
/&#47!!void main(){
TMOD=0x21;开总中断 ET0=1;
}/O移位就可以了
TH0=0x3c;&#47:T0中断服务程序void time0() interrupt 1{
中断20次向下执行I//初始化定时器T0为工作方式 TH0=0x3c;/
/名称;/启动T0定时器
while(1)很简单的
我再帮你补一课,看了你的标题,我写了一个用定时器0来控制一个LED灯第隔1秒钟亮灭一次的程序,希望对你有用,另外我也写了一个你说的那个程序,一起发上来吧
****************这个是用定时器0控制一个灯的亮和灭******************************
#include&reg52.h&
#define uchar unsigned char
#define uint unsigned int
/**************************************/
sbit d=P1^0;
/******************主程序入口********************/
void main()
TMOD=0x01;
TH0=()/256;
TL0=()%256;
TCON=0x10;
if(num==20)
