我自己编写的atmega16的485通讯的范例

	.module mian.c
	.area text(rom, con, rel)
	.dbfile J:\自编程序\M16\485bus\mian.c
	.dbfunc e main _main fV
	.even
_main::
	.dbline -1
	.dbline 6
; #include<iom16v.h>
; #include<macros.h>
; //#define 485bus_recive PORTD|=0X04;
; //#define 485bus_send PORTD&=0XFB;
; void main (void)
; {
	.dbline 7
;    USART_Init();
	xcall _USART_Init
	xjmp L3
L2:
	.dbline 9
	.dbline 10
	xcall _USART_Recive
	xcall _USART_Transmit
	.dbline 11
L3:
	.dbline 8
	xjmp L2
X0:
	.dbline -2
	.dbline 11
;    while(1)
;    {
;    USART_Transmit(USART_Recive());
;   }}
L1:
	.dbline 0 ; func end
	ret
	.dbend
