摘要
串口设备是嵌入式系统经常用到的设备之一,其本身具有很高的数据传送精度,但是如果使用方法不当,也会造成数据接收的误码率显著增大。本文以某控制系统为例说明正确的使用方法可以显著提高串口接收的可靠性。
Serial device is one of the equipment used in the embedded system. It has a high precision of data transmission. While if the use of the method is improper, the error rate of the data receiving will be significantly increased. In this paper, a certain type of control system is taken as an example to show that the correct use method can significantly increase the reliability of serial port reception.
