Question

Any forks of the Standard Peripheral Libraries?

Hi all:

I have a number of firmwares which use the older Standard Peripheral Library for STM32F4xx etc.

I could switch to the new Low-Layer drivers, but I doubt it is worth the effort.

I actually found the old Standard Peripheral Libraries quite all right. Unfortunately, STM is not maintaining them anymore, even in the face of obvious bugs like this one:

Standard Peripheral Library limits STM32F4xx USART to 7.5 Mbit/s, instead of max 10.5 Mbit/s

Are there any community forks of the Standard Peripheral Libraries I could switch to?

Thanks in advance,

Not that I’m aware of.

I mostly use the SPL  for projects with MCUs for which a SPL exists, and modify the SPL code if necessary.
