51单片机及AVR单片机的串口通信及Proteus仿真-2 单片机, 通信

苹果也疯狂

最后把程序附上，里面有些变量声明了没有用到，当初只是实验。。

51的：

#Include "Reg52.H"

#Define AA 0x61

#Define Commun_symbol 0x31

Sbit LED=P2^0;

Unsigned Char Tx[]={"My Name Is Seven!"};

Void Uart_init(Void)

{

  SCON   = 0x50;

  RCAP2H = 0xFF;

  RCAP2L = 0xD9;

  TH2    = 0xFF;

  TL2    = 0xD9;

  T2CON  = 0x34;

  

}

Void Uart_send(Unsigned Char ByData)

{

TI=0;

SBUF=ByData;

While(TI==0);

TI=1;

}

Unsigned Char Uart_receive(Void)

{

RI=0;

While(RI==0);

RI=1;

Return(SBUF);

}

Void Main()

{

Unsigned Char ByBuff,I;

Uart_init();

Uart_send(Commun_symbol);

While(1)

{

  

  

  ByBuff=Uart_receive();

  LED=1;

  If(ByBuff==0x31)

  {

   For(I=0;I<20;I++)

  {

   P1=ByBuff;

   Uart_send(Tx[I]);

  }

  }

}
