All STM32 HAL libraries

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!

All examples for Keil uVision can be downloaded from my Github repository.

Libraries API

I’ve added doxygen documentation on my site for HAL based libraries. It is available on this link where you can find descriptions for used functions in my libraires.

All libraries

Libraries listed below are currently tested on F7 and F4 series and works OK. If you find any bug, please report it to me.

I’m not responsible for any damage you will do using my libraries. You at your own risk!
