點(diǎn)亮一小燈 然后從左到右，
#include <reg52.h>

sbit ADDR0 = P1^0;
sbit ADDR1 = P1^1;
sbit ADDR2 = P1^2;
sbit ADDR3 = P1^3;
sbit ENLED = P1^4;
void main()
{
unsigned int i = 0;
unsigned char cnt = 0;
unsigned char sec = 0;
unsigned char dir = 0;
unsigned char shift = 0x01
ADDR3 = 1;
ENLED = 0;

ADDR1 = 1;
ADDR0 = 0;
TMOD = 0x01;
TH0 = 0xB8;

while (1)
{
if (TF0 == 1)
{

cnt++;
if(cnt >=100)
{

LED = ~LED;
}
{

for(i=0; i<30000; i++);
if (dir == 0)
{

if ( shift == 0x80)
{

}
}
else
{

if (shift == 0x01)
{
