STC15W104单片机领航灯制作芯片解密
单片机源程序如下:
- 芯片解密#include <reg51.h>
- 芯片解密#include <intrins.h>
- sbit LED = P3^5; // LED连接在P3.5
- sbit KEY1 = P3^3; // 外部中断0按键连接在P3.3
- sbit KEY2 = P3^3; // 外部中断1按键连接在P3.5
- //*********延时函数***********//
- void delay(unsigned int a )
- {
- unsigned int i;
- while (--a !=0)
- {
- for (i=0; i<=600; i++);
- }
- }
- //*********主程序***********//
- void main()
- {

- EX1 = 1; // 使能外部中断1
- EA = 1; // 使能总中断
- while(1)
- {
- if(KEY1 == 0) // 当按键1按下时
- {
- delay(10); // 去抖
- if(KEY1 == 0)
