STM32 L522C . I want to get chip to sleep mode and wake it up by time interrupt of 32KHz clock . How do I?

I'm about to start embedded programming and have an STM32f103C8T6 ARM-Coretex-M3 board to get started with. I'm also a C++ programmer and want to use that language to program a project to blink the LED of that board as my first embedded task.

Hi all, Apart from the board and two machines (Windows and Linux) I have also an MB-102 breadboard and a bunch of cables in hands. Firstly I wanted to make use of this tutorial for the task above but it's dealing with NUCLEO-L476RG that I lack for th...
