電路原理圖如下：

單片機源程序如下:

#include<pic.h>
#include <xc.h>
#pragma config WDTE = OFF // Watchdog Timer (WDT disabled)
#pragma config CP = OFF // Code Protect (Code protection off)
#pragma config MCLRE = OFF // Master Clear Enable (GP3/MCLR pin fuction is digital I/O, MCLR internally tied to VDD)
#define led1 GP0
#define led2 GP1
#define led3 GP2
#define key GP3
void DELAY(unsigned int n)
{
unsigned int j;
unsigned int k;
for(j=0;j<n;j++)
for(k=200;k>0;k--)
NOP();
}
void main()
{
GP0=GP1=GP2=0;
unsigned char num=0;
TRISGPIO=0b00001000;
OPTION=0B010000111;
OSCCAL=0b11111110;
while(1)
{
if(key==0)
{
DELAY(20);
if(key==0)
{
while(!GP3);
num++;
}
}
if(num==7)
{
num=0;
led1=led2=led3=0;
}
if(num==1)
{
led1=1;led2=led3=0;
}
if(num==2)
{
led2=1;led1=led3=0;
}
if(num==3)
{
led3=1;led1=led2=0;
}
if(num==4)
{
led1=led2=1;led3=0;
}
if(num==5)
{
led1=led3=1;led2=0;
}
if(num==6)
{
led2=led3=1;led1=0;
}
}
}
