CMSIS and HAL at one project integrating CMSIS and HAL

Question

I am wondering, is it possible to add CMSIS and HAL libraries at the same project in KEIL... based on my knowledge I added CMSIS libraries in different folder but in compiling I got these errors...

Do you guys have faced with this problem? Can you help me? note: the main project was written in CMSIS and I don't want to rewrite it in Hal. There are 2 files:1-stm32f4xx_hal.h,2-stm32f4xx.h The first one is defined and used in HAL and the second one is for CMSIS, how can I use both of them in one project? THIS IS THE ERROR:" #error "Please select first the target STM32F4xx device used in your application (in stm32f4xx.h file)" " and in below is the screenshot.

THANKS.

Answer 1

The STM32 HAL always depends on CMSIS. You cannot use the HAL library without CMSIS.

The error message you have received clearly explains what you have done wrong and what you need to do to fix it. I cannot explain it any more clearly than that.

#error Please select first the target STM32F4xx device used in your application

You might also appreciate to read the comment immediately before the line you have highlighted:

/*  Tip: To avoid modifying this file each time you need to switch between these
    devices, you can define the device in your toolchain compiler preprocessor.
