Arduino for STM32

Hi everyone, ı want to use deep sleep mode on my stm32f103c8t6. I have two library but it gives error, ı can't compile it. How can ı put to sleep my stm32? Does it need library? If ı don't need library how can ı do this? Thanks for your help.

My Errors:
Using: C:\Users\ufukc\Documents\Arduino\libraries\STM32LowPower-main

Compilation error for generic STM32F103C6/fake STM32F103C8 board.

The STM32LowPower is for the STM32 core but you used Roger's core that's why you got this error as it is not compatible.

So, what can ı do?

You have to use registers to set MCU into sleep modes:
eg. in this thread: viewtopic.php?f=63&t=464

or switch to official STM32 core
