HAL library 10- CRC for STM32Fxxx 1

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....

In this section, I will write all libraries based on HAL drivers from ST. If you see this first time, make sure you read this post first about how structure of my libs looks like!

Library 47- CRC module on STM32F4

STM32F4xx 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. STM32F4 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....

Because there is a lot of libraries I have done, I will make a table with all of my libraries at one place. When new library will be created, it will be posted here. These libraries work on both Discovery boards, if not, it will be specified. Actually, libraries should work on STM32F4xx series of microcontrollers if they have peripherals that are need for library. All STM32F4xx MCUs don’t have everything inside. 🙂 Libraries are tested on my 4 STM32F4...
