defined things called "undeclared"

Hi, my processor is STM32L010C6TX. I added function to my project to use microsecond But " DWT" "CTRL" etc. It says not defined. However, they are all in the "core_cm4.h" library. This library is in Drivers-> CMSIS->Include. why doesn't it call this function and say "undeclared"?

Maybe you don't have given header file included (directly or indirectly) in the source file where the error occurs.

~~Try to #include it explicitly~~.

The STM32L010C6TX use a M0+ core not a M4 core. So look at core_cm0plus.h

In M0/M0+ core there is no DWT

Hello, thank you very much for your information.

Is there any other way to use this library?

dwt_stm32_delay.h

dwt_stm32_delay.c

@Khouloud OTHMAN ST should really do a better job here of only copying the core file(s) used by that family. There's no reason to have headers for all different Cortex types within a project. No need to have Cortex-M4 specific files in a Cortex-M0+ project.
