UART_TXaRX
单片机接收从电脑串口发送出来的一串字符串,却只能接收到第一个字符,其他的都丢失了或者是接收到的是乱码,却不知道是什么原因。其实,那是因为,虽然单片机的是全双工串口,但是串口的缓冲区(SBUF)却一般只有一个字节,即1Byte,远没有像电脑串口的缓冲区以KB计算那么大,并且,单片机的处理速度是很有限的,试想一下,假如要求一串字符串以9600bps的速率,一个起始位,一个结束位,无校正位,相当于960Byte/s传输到单片机,单片机要是能够全部接收的话,那么单片机接收和处理一个字节的时间仅为约1ms的时间。这说明了,如果单片机的处理速度不够快,还没有将接收到的上一帧数据及时转送到单片机的RAM中,而电脑串口又传输过来一帧新的数据,这帧新的数据就会把单片机的串口输入缓冲区的SBUF给刷新掉,或者说单片机压根就没有接收到新的一帧数据,造成了数据的丢失或接收到乱码。
如果需要单片机接收到从串口发送过来的一段很长的字符串,并且能够都正常接收和显示(TX&RX FUNCATION between PC and MCU)
