需要的师兄下载附件，求帮助
单片机源程序如下:
- /*************** writer:shopping.w ******************/
- #include <reg52.h>
- #define uchar unsigned char
- #define uint unsigned int
- sfr WDRST = 0xA6;
- sbit LED1 = P0^0;
- sbit LED2 = P0^1;
- sbit K1 = P1^4;
- void DelayMS(uint ms)
- {
- uchar i;
- while(ms--)
- {
- for(i=0;i<120;i++);
- }
- }
- void main()
- {
- LED1 = 0;
- LED2 = 1;
- DelayMS(2000);
- TMOD = 0x01;
- TH0 = -16000/256;
- TL0 = -16000%256;
- IE = 0x82;
- WDRST = 0x1E;
- WDRST = 0xE1;
- while(1)
- {
- if(K1==0)
- {
- TR0 = 0;
- LED1 = 1;
- LED2 = ~LED2;
- DelayMS(200);
- }
- }
- }
- void Timer0() interrupt 1
- {
- TH0 = -16000/256;
- TL0 = -16000%256;
- WDRST = 0x1E;
- WDRST = 0xE1;
- }
