What core am I using ?

[ChoCho]

Hi everyone,

I have tried and installed several STM32 cores to see which one suite my need.

But I forget what core now I am using !

How do I check out which core and what version I am using ? Thanks you.

Well,
Enable the compile log then share it or a screenshot of the tools menu.

in Tools menu the Roger Clark's core boards are in "STM32duino section". The STM core has only "STM32" in the title. If you installed with Boards Manager you can look in Boards Manager, what boards package is installed.
