使用搭配最小系统就能实现了。
关键在定时器上面,源码源程直播配置接口源码如果不需要精确的秒表秒表spring 循环依赖源码就用C写个延迟函数。
具体可参考我的源码源程推荐算法java源码空间:
单片机数码管显示数字递增
关键字: 单片机 动态扫描 数码管 整数递增 让单片机的数码管显示的数从0开始递增一直到,然后重新置0,再递增,如此循环.
还是用到了将要显示的数进行百位,十位,个位的分离.
从这篇开始,以后的程序就要注意程序的规范性,与可读性了.源代码如下(已经成功调通):
C代码
#include<reg.h>
#define uint unsigned int
#define uchar unsigned char
sbit sda = P1^0;
sbit clk = P1^1;
sbit dig1 = P1^2;
sbit dig2 = P1^3;
sbit dig3 = P1^4;
sbit dig4 = P1^ 5;
uchar code table[]={ 0x7e,0x0c,0xb6,0x9e,0xcc,0xda,0xfa,0x0e,0xfe,0xde};
uchar times;
void init();
void delay(uchar);
void write(uchar);
void display(uchar);
void main()
{
uchar i = 0;
init();
while(1)
{
display(i);
if(times>2)
{
times = 0;
i ++;
if(i==)
i = 0;
}
}
}
/** 显示一个3位的整数 **/
void display(uchar num)
{
uchar bai,shi,ge;
bai = num/;
shi = num%/;
ge = num%;
/* 显示个位 */
dig4 = 0;
write(table[ge]);
delay();
dig4 = 1;
/* 显示十位 */
dig3 = 0;
write(table[shi]);
delay();
dig3 = 1;
/* 显示百位 */
dig2 = 0;
write(table[bai]);
delay();
dig2 = 1;
}
/** 程序初始化函数 **/
void init()
{
clk = 0;
times = 0;
TMOD = 0x; //定时器模式1
TH0 = (-)/; //每毫秒产生一次中断
TL0 = (-)%;
TR0 = 1; //开始计时
EA = 1; //打开总中断开关
ET0 = 1;
}
/** 向数据码管写入一个字节数据 **/
void write(uchar u)
{
uchar i;
for(i=0;i<8;i++)
{
clk = 1;
sda = u&0x;
clk = 0;
u = u<<1;
}
}
/** 延迟函数 **/
void delay(uchar t)
{
uchar x,y;
for(x=t;x>0;x--)
for(y=;y>0;y--);
}
/** 1号中断 **/
void timer0() interrupt 1
{
TH0 = (-)/; //每毫秒产生一次中断
TL0 = (-)%;
times ++;
}
