当发送机按键按下后，接收机LED灯被点亮
单片机源程序如下:
- #include <reg52.h>
- #define uint unsigned int
- #define uchar unsigned char
- uchar state;
- void receive()
- {
- while(RI==0);
- state=SBUF;
- RI=0;
- }
- void SCON_Init()
- {
- TMOD=0x20;
- SCON=0x50;
- PCON=0x00;
- TH1=0xfd;
- TL1=0xfd;
- TR1=1;
- REN=1;
- }
- void main()
- {
- P1=0xff;
- SCON_Init();
-
- while(1)
- {
- receive();
- P1=state;
-
- }
- }
