Automatic choice of a header by a used STM.

[Filipx.87]

Hi! I have the own include file which contains more the same HAL libraries headers with a different types of controllers. Could it be some possible (with Directive and Contitions?) for a compiler to choose itself according to the used controller in Project? Thanx.

I always have to choose manually...

// #include "stm32l1xx_hal.h"

#include "stm32f1xx_hal.h"

//#include "stm32f4xx_hal.h"

// #include "stm32f7xx_hal.h"

Doesn't the compiler command line, by way of the project meta-data, get a definition passed of the platform/cpu being used?

ie STM32L432xx

And things like

#if defined (STM32L412xx) || defined (STM32L422xx) || defined (STM32L431xx) || defined (STM32L432xx) || defined (STM32L433xx) || defined (STM32L442xx) || defined (STM32L443xx) || defined (STM32L451xx) || defined (STM32L452xx) || defined (STM32L462xx) || defined (STM32L4R5xx) || defined (STM32L4R7xx) || defined (STM32L4R9xx) || defined (STM32L4S5xx) || defined (STM32L4S7xx) || defined (STM32L4S9xx)

/* The temperature sensor measurement path (channel 17) is available on ADC1 */

#define ADC_TEMPERATURE_SENSOR_INSTANCE(__HANDLE__) (((__HANDLE__)->Instance) == ADC1)

#elif defined (STM32L471xx) || defined (STM32L475xx) || defined (STM32L476xx) || defined (STM32L485xx) || defined (STM32L486xx) || defined (STM32L496xx) || defined (STM32L4A6xx)  

/* The temperature sensor measurement path (channel 17) is available on ADC1 and ADC3 */

#define ADC_TEMPERATURE_SENSOR_INSTANCE(__HANDLE__) ((((__HANDLE__)->Instance) == ADC1) || (((__HANDLE__)->Instance) == ADC3))

#endif

OR

#if defined(STM32L1) || defined(STM32L4) || defined(STM32G0) || defined(STM32L5)

#define HAL_DAC_MSP_INIT_CB_ID    HAL_DAC_MSPINIT_CB_ID

#define HAL_DAC_MSP_DEINIT_CB_ID   HAL_DAC_MSPDEINIT_CB_ID

#endif

STM32 headers are meant to be used like this:

#define STM32F767xx
#define USE_HAL_DRIVER
#include "stm32f7xx.h"

Or you can put those defines in a project configuration.

But, if you're building a single project for multiple boards, you should have some BSP layer. Then you can put MCU specific defines and includes in BSP files.
