我自己编写的atmega16的485通讯的范例

NOTE: AVR Code addresses are word addresses
All other addresses (including ones in FLASH) are byte addresses

Area                               Addr   Size   Decimal Bytes (Attributes)
--------------------------------   ----   ----   ------- ----- ------------
                            text   0054   007C =    124. bytes (rel,con,rom)

       Addr  Global Symbol
      -----  --------------------------------
       002A  __text_start
       002A  __start
       004A  _exit
       004B  _main
       0054  _USART_Init
       005D  _USART_Transmit
       0061  _USART_Recive
       0065  _USART_Recive_Complete_handler
       0066  _USART_Data_Register_Empty_handler
       0067  _USART_Transmit_Complete_handler
       0068  __text_end

Area                               Addr   Size   Decimal Bytes (Attributes)
--------------------------------   ----   ----   ------- ----- ------------
                          vector   0000   0038 =     56. bytes (abs,ovr,rom)
