Hi,

I don't use IAR anymore but I will try to help you.

In my memories, IAR is not provided with the libraries. You need to download them on the ST site.

On the view, you you selected a target device but you didn't indicate a symbol to use as preprocessor.

To define a symbol, you need to go to the "C/C++ Compiler" category and add the symbol (STM32F103xB in your case (for STM32F103R8)) in the "preprocessor" tab.

Or you can uncomment the line corresponding to your device in the file "stm32f10x.h".
