STD peripheral and Hal driver

[NSemrHomeInit]

Dear ST Hello,

What is the deference between Std peripheral drivers and Hal drivers please?

Some project use the std peripheral and IDE cube uses the Hal drivers, could you please clarify this point?

Thank you in advance,

S.Tarik

SPL is the older style API, similar to that available for the STR7 and STR9 series parts

If you have an existing working project using SPL, probably safer left alone. If you need to refresh the design to newer STM32 parts you might want to consider refactoring, using the HAL, LL, register level or pseudo-SPL
