关于CRC8CRC16CRC32，你要找的全部在这 循环冗余校验（英语：Cyclic redundancy check，通称“CRC”）是⼀种根据⽹络数据包或电脑⽂件等数据产⽣简短固定位数校验码的⼀种散列函数，主要⽤来检测或校验数据传输或者保存后可能出现的错误。循环冗余校验 Wikipedia ⼀句话：CRC是将数据计算出散列的⽅式，...

⾸先需要明确CRC8常见的表格数据中是按照线传输LSB，并通过右移寄存器来判断的，因此每次要判断的就是寄存器的最低位LSB。同时要将多项式X^8+X^5+X^4+X^0 （也就是0x131(0011 0001)）按位颠倒后得到0x8c(1000 1100)，在计算过程 中做异或运算（为什么0x131中第⼀个1没有被颠倒？答：因为它是隐藏...
