Principle of CRC algorithm and Implementation of C LanguageAbstract This paper theoretically exports the implementation principle of CRC algorithm, and provides three C language programs that adapt to different computer or microcontroller hardware

Because I encountered many problems when designing the CRC module, I did not find an article with practical guidance on the Internet. After several simulation modifications and simulation, I got the correct result, therefore, we are willing to

CRC (Cyclic redundancy check) calibration application is more extensive, previously in order to deal with the simple, most of the program using LRC (longitudinal redundancy check) checksum, LRC check very well understood that the programming is

CRC (Cyclic Redundancy Check) Verification is widely used. In the past, LRC (Longitudinal Redundancy Check) verification was used in most programs for simple processing. LRC verification is well understood and easy to implement. I studied the C

With the development of computer technology, the industrial control of data communication using microcomputer has been applied more and more widely in modern industry. The communication data between the computer and the controlled device often

Unknown Source     With the continuous development of computer technology, Industrial Control Using Microcomputer for data communication is also widely used in modern industry. Due to the influence of transmission distance, on-site conditions, and

The CRC checksum can be used to validate the data during transmission, when sending valid data, the CRC check code is computed according to the valid data and generating polynomial (such as CCITT Standard polynomial is x16+x12+x5+1), and the CRC

CRC16 Implementation CodeIdea: Take a character (8bit), check the character bit by digit, if it is 1,crc^crc_mul, and if the original CRC highest bit is 1, then crc^crc_mul the left 1 bits, otherwise it just moves left one bit. After calculating one

Abstract: CRC (cyclic redundancy check) is widely used in error detection during data communication.Error Checking capability. This article describes in detail the basic principles of CRC and explains the concept of the common lookup
