单片机计数器C程序

Question

谁能提供一个单片机STC89C58RD的计数器程序（0-9999），不盛感激！

Answer 1

#include<reg51.h>
#define uchar unsigned char
uchar j,k,i,a,A1,A2,second;
sbit dula=P2^6;
sbit wela=P2^7;
uchar code table[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,
0x07,0x7f,0x6f,0x77,0x7c,0x39,0x5e,0x79,0x71};
void delay(uchar i)
{
for(j=i;j>0;j--)
for(k=125;k>0;k--);
}
void display(uchar sh_c,uchar g_c)
{
dula=0;
P0=table[sh_c];
dula=1;
dula=0;

wela=0;
P0=0xfe;
wela=1;
wela=0;
delay(5);

P0=table[g_c];
dula=1;
dula=0;

P0=0xfd;
wela=1;
wela=0;
delay(5);
}void main()
{
while(1)
{
second++;
if(second==60)
second=0;
A1=second/10;
A2=second%10;
for(a=50;a>0;a--)
{ display(A1,A2);};
} }这是0到59的你改一下就可以了~！
