Hi!

I

necessity to use

the standard libraries

for

microcontroller

STM32L052K8

.

If there is

, where

can I download

?

thanks

There is none and probably never will be.

The ''Snippets'' show you how. JW

I have a project being developed with a microcontroller STM32F051K8 CoIDE to be translated for STM32L052K8 . The libraries STM32SnippetsL0 can replace the standard libraries ?

I understand your problem, but I have no easy solution for it. You'll have to either rewrite your project for ''Cube'' libraries (this is what ST would recommend at this moment), develop a (possibly stripped-down) version of the standard peripheral library for the 'L0 (this is what I'd expect from Clive to recommend 😉 ), or to rewrite your project for direct register access, without the ''library'' (this is what I would recommend). There is also a community-driven initiative out there to write a replacement for the Standard Peripheral Library for STM32, but I don't know its status (and I don't even know its name :| ) > The libraries STM32SnippetsL0 can replace the standard libraries ? No. Snippets are no libraries, they are examples of how to program STM32 low level without any libraries, just using the definitions provided in the stm32xxxx.h header. JW

Yeah, perhaps...

I don't have much time or effort invested in the L0, though I did go to the seminar the other week. I guess you have to decide how much effort it is to port it to the HAL libraries, code a subset of the SPL, or go commando and code a register level solution. Given the trade-offs, I might tend toward the latter. The current trend seems to be to make the abstraction thicker whilst make the the speed/resources smaller. I see the Cortex-M0 as a bit of a design regression. You need to determine what your design needs, and commit resources at that.
