We are using the Keil compiler and a ST device.
We are trying to figure out which files to use for our ST device (STM32F2xx).
We would like to use the ST standard peripheral libraries. It contains CMSIS folder and the peripheral libraries. Can we reference the STM32F2xx.h file from this CMSIS folder? Must we also reference the core header files (e.g. core_cm3.h) from this folder(s)?
The issue that we have at the moment (and we think we will have more issues in future with this) is that the stm32f2xx.h file is located under keil\arm\inc\st\stm32f32xx. We need to modify this file to for example, modify the HSE_VALUE, because our system runs at a different frequency.
We believe that because of this, we should rather include the CMSIS library separately from the compiler, however, we are not sure how it affects the Keil libraries (.lib files).
We have for example a newer version of the ST peripheral library, but we are not sure if we can use it or not?
Could someone please give us some insight on how to go about using the CMSIS library without it being tied to Keil compiler. Also, we would like to easily switch to any new versions of the peripheral library should ST make it available. Thanks in advance for your response.

They are all ST files - Keil simply includes a copy of ST's files with their installation.
I would recommend that you should, wherever possible, go direct to the source - in this case, ST.
It has been the case (maybe still is) that what Keil shipped was out-of-date and incompatible with the current version direct from ST - which meant that none of the current examples from the ST site would work if you used the Keil-supplied stuff. So, again, I recommend going direct to the source.
