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!
