STM32C8T6接收

主要分為串口中斷，超時(shí)方式接收，比較
超時(shí)方式接收被放到了主循環(huán)，配合串口中斷使用，是一個(gè)不太成熟的函數(shù)，不過(guò)用在這里綽綽有余。

//串口中斷函數(shù)：
 u8 rev_buf[100];//接收緩沖區(qū)
 u8 addr=0;     //地址偏移量
 u8 revice_ok=0;//接收完成標(biāo)志
 u8 revice_start=0;//開(kāi)始接收受標(biāo)志
 u32 time_out=0;//超時(shí)計(jì)數(shù)值
//串口1中斷服務(wù)函數(shù)

void USART1_IRQHandler(void)
{
	u8 data;
	
	data=USART1->DR;//讀取同時(shí)會(huì)清除標(biāo)志
	rev_buf[addr++]=data;
	//printf("addr:%drn",addr);
	
	revice_start=1;//開(kāi)始接收
	time_out=0;//超級(jí)計(jì)數(shù)值清零
}

//串口中斷接收函數(shù)
int ld3320_uart_receive(void)
{
	//char * buf = NULL;
	int num = 0;
	if(revice_ok)
	{
			revice_ok=0;//清標(biāo)志
			printf("%srn",rev_buf);
		
			printf("%srn",rev_buf);
			printf("rev_buf is ok rn");
		  num = compare_usart((char *) rev_buf);
		 return num;
		}
	
	if(revice_start)//開(kāi)始接收
	{
			Main_delay();
			time_out++;
		  num=0;
			if(time_out>=50)//超時(shí)就
			{
				revice_ok=1;
				rev_buf[addr]='?';
				addr=0;
				time_out=0;
				revice_start=0;
			}
	}
	return 0;
}
