摘要
在数据通信中,由于诸多因素的影响,设备之间的通信数据常常会发生一些无法预测的错误.为确保高效而无差错地传输数据,降低错误所带来的影响,必须对数据进行检错,即差错控制.一般在通信时采用数据校验的办法,在诸多检错手段中,CRC是最著名的一种.利用51系列单片机可以实现CRC.
In data communications, several unexpected errors may occur dtie to various factors. Therefore, in order to ensure that the process of data transmission goes effienciently and precisely, and to limit the immeasurable losses brought by these errors, it＇s necessary to correct the data, which is also known as error control. As widely accepted, to check the data is generally the basic means. And among a variety methods of this means, CRC is regarded as the most famous one, which can be achieved with MCU in 51 series.
