@R0b0t1:

FYI, I have now implemented Clock Configuration and gpio for stm32l4 
chips, the blinky program works now, please pull latest mdf libs from 
github.

Why do you think STM32 chips are poorly documented?

The Reference Manuals are pretty good an the code generated by 
STM32CubeMX is very helpful to better understand the inner working of 
the Chips.
