Linker issues

Hello All,

I am using Keil u vision4 for stm32f2 series.

I am building anSPI application using SPI libraries provided by STM. I am not able to recognise the problem. If i include those libraries in my file, i get these errors

If i do not include the #include "stm32f2xx_spi.h"
#include "stm32f2xx_gpio.h"
#include "stm32f2xx_rcc.h" files, i get all the spi related stuffs as undefined.

Could any one pls suggest me how to include these library and make my code work??
Thanks

    Hi,

    Thanks. I was able to resolve the previous errors.But now i am getting new set of linker errors.
    Is there anything i have to add any LIB file for this to work.
    But i could not find any LIB file specificaly for stm32f2xxx series.

    Could you pls help me knowing whats the soultion

    Build target 'Target 1'

    Thanks Andrew!!

    I got it working

    I included the library files needed along with my files. And compiled.

    So now its working fine.

    Thanks

    That's right: ST don't provide a ready-built library - so you have to include the source files in your project, and build them as part of your project.

    (or you could create your own library, if you wanted)

    "I included the library files needed along with my files. And compiled. So now its working fine."

    That's it - well done!

    "Thanks"

    You're welcome.
