用c语言实现crc算法，采用ccitt标准多项式，查找表方法实现，低位先处理，接收校验成功标志为f0b8.-Checksum crc algorithm to achieve the standard which use ccitt polynomial, using look-up table method to achieve, low bit to deal with first, mark of success receiving check is f0b8.

用c语言实现crc算法，采用ccitt标准多项式，查找表方法实现，高位先处理，接收校验成功标志为1d0f.-Checksum crc algorithm to achieve the standard which use ccitt polynomial, using look-up table method to achieve, high bit to deal with first, mark of success receiving check is 1d0f.

CRC校验C语言实现,CRC(Cyclic Redundancy Check)校验应用较为广泛，以前为了处理简单，在程序中大多数采用LRC(Longitudinal Redundancy Check)校验，LRC校验很好理解，编程实现简单。用了一天时间研究了CRC的C语言实现，理解和掌握了基本原理和C语言编程。结合自己的理解简单写下来。-CRC, C language, CRC (Cyclic Redundancy Check) verification is widely used, prev
