HAL library 10- CRC for STM32Fxxx

STM32Fxxx devices have CRC (Cyclic Redundancy Check) module inside. This is small and useful unit when working with communications. It might become very useful to verify if your packet of data is correct.

STM32Fxxx devices uses “Ethernet” CRC with polynomial below:

X32 + X26 + X23 + X22 + X16 + X12 + X11 + X10 +X8 + X7 + X5 + X4 + X2 + X +1

It is quite ugly 😀 Well, using this module is very easy. I’ve made some functions to calculate CRC from block of data.
