這是我在設計上設計的51單片機（stc98c52）與藍牙模塊（hc-08）連接，利用藍牙透傳模式做的相互通訊系統。
單片機源程序如下:
- #include <reg51.h>
- #define uint unsigned int
- #define uchar unsigned char
- void UsartInit();
- void Delay1ms(uint c) ;
- uchar receiveData;
- uchar code table[]={0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,
- 0xf8,0x80,0x90};
- void main()
- {
- UsartInit();
- while(1);
- }
- void UsartInit()
- {
- SCON=0X50;
- TMOD=0X20;
- PCON=0X80;
- TH1=0XFA;
- TL1=0XFA;
- ES=1;
- EA=1;
- TR1=1;
- }
- void Delay1ms(uint c)
- {
- uint a,b;
- for(a=c;a>0;a--)
- for(b=112;b>0;b--);
- }
- void Usart() interrupt 4
- {
- receiveData=SBUF;
- RI = 0;
- SBUF=receiveData;
- while(!TI);
- TI=0;
- if(receiveData=='0')
- P0=table[0];
- else if(receiveData=='1')
- P0=table[1];
- else if(receiveData=='2')
- P0=table[2];
- else if(receiveData=='3')
- P0=table[3];
- else if(receiveData=='4')
- P0=table[4];
- else if(receiveData=='5')
- P0=table[5];
- else if(receiveData=='6')
- P0=table[6];
- else if(receiveData=='7')
- P0=table[7];
- else if(receiveData=='8')
- P0=table[8];
- else if(receiveData=='9')
- P0=table[9];
- else
- P0=~table[8];
- Delay1ms(1000);
- }
