I haven't written a 51 microcontroller program for a long time. I wrote a small program to practice.
#include //Include header file
#include
#define uchar unsigned char
uchar temp;
void delayms(int ms);
void main()
{
temp=0x01;
P1=temp; //Turn on the first light
while(1)
{
temp=_crol_(temp,1);
delayms(600);
P1=temp;
}
}
void delayms(int ms)
{
int i,j;
for(i=0;i
for(j=0;j<120;j++);
}
