Altium Designer画的原理图和PCB图如下：(51hei附件中可下载工程文件)
单片机源程序如下:
- #include <reg52.h>
- #define uchar unsigned char
- #define uint unsigned int
- sbit LED0 = P1^0;
- sbit LED1 = P1^1;
- sbit LED2 = P1^2;
- sbit LED3 = P1^3;
- void delay_ms(uint ms)
- {
- uint i,j;
- for(i = ms;i > 0; i--)
- for(j = 120;j > 0; j--);
- }
- void main()
- {
- while(1)
- {
- LED0 = 0;
- LED1 = 0;
- LED2 = 0;
- LED3 = 0;
- delay_ms(1000);
- LED0 = 1;
- LED1 = 1;
- LED2 = 1;
- LED3 = 1;
- delay_ms(1000);
- }
- }
