用SL811做USB主机的源码

//TXB8=UCSRB.0    RXB8=UCSR.1
#define S_Max 10
unsigned char send_offset=0,send_tab[S_Max]={2,1,5,6,3,2,1,5,6,3,};


void sd_data(unsigned char *data)
{	 UDR0=*data;
	 
}



#define send_data(data) sd_data(&data)
void send_datas(void)
{	 if (send_Enable)
	 	{send_data(send_tab[send_offset]);
		 send_offset++;
		 if (send_offset==S_Max) {send_offset=0;send_Enable=0;}
		}
}
