51单片机及AVR单片机的串口通信及Proteus仿真-3 单片机, 通信

苹果也疯狂

AVR Atmega64的程序：

两个文件，一个是将函数模块化，别一个是主函数，调用（- -！最近习惯将程序模块化。。。）

//------------------Uart.C---------------------

//----这里将通信函数模块化------------

#Include <Iom64v.H>

Void Uart0_init(Void)

{

UCSR0B = 0x00; //Disable While Setting Baud Rate

UCSR0A = 0x00;

UCSR0C = 0x06;

UBRR0L = 0x33; //Set Baud Rate Lo

UBRR0H = 0x00; //Set Baud Rate Hi

UCSR0B = 0x18;

}



Void Uart0_Transmit( Unsigned Char Data )

{

/* Wait For Empty Transmit Buffer */

While ( !( UCSR0A & (1<<UDRE0)) )

;

/* Copy Ninth Bit To TXB8 */

UCSR0B &= ~(1<<TXB80);

//If ( Data & 0x0100 )

//UCSR0B |= (1<<TXB80);

/* Put Data Into Buffer, Sends The Data */

UDR0 = Data;

}

Unsigned Char Uart0_Receive( Void )

{

/* 等待接收数据*/

While ( !(UCSR0A & (1<<RXC0)) )

;

/* 从缓冲器中获取并返回数据*/

Return UDR0;

}

//--------------Main.C-----------

//--------------------------------

#Include <Iom64v.H>

#Include "Spi.H"

#Define Commun_symbol 0x31

//-----------Send A Commun_symbol-----

//-----------Receive A Commun_symbol--

//      <--No,Continue Receive||||||Yes-->Receive The Data And Send

Void Main()

{

Unsigned Char Bybuff;

DDRB=0xff;

PORTB=0xff;

Uart0_init();

  {

  

  Do

  {

  Bybuff=Uart0_Receive();

  }

  While (Bybuff!=Commun_symbol);//Commun_symbol);

  While(1)

  {

   

Uart0_Transmit(Bybuff);

Bybuff=Uart0_Receive();

PORTB=(0xff|Bybuff);

  }

}

}

Ok,任务完成了,改天实验一下!
