X-CUBE-SMBUS Middleware not supported for STM32F407

[Nandan V]

Is there any way to use the X-CUBE-SMBUS middleware from ST with STM32F407?

The controller does support it but ST's middleware does not.

Does anyone know why it would not be supported?

The reason I say its not is because the HAL for it is not in the #ifdef switches as shown in the code snippet below.

// From en.x-cube-smbus_v2.0.3/STM32_AN4502_FW_V2.0.3/Middlewares/ST/STM32_SMBus_Stack/inc/stm32_SMBUS_stack.h
 
#include "stm32_config_stack.h" 
 
#ifdef STM32F072xB
#include "stm32f0xx_hal.h"
#endif
 
#ifdef STM32F303xC
#include "stm32f3xx_hal.h"

#endif

Hello @Community member​ ,

There is no plan yet to modify the SMBUS middleware to support and use the STM32F4 HAL driver.

Please have a look at this post for more details.

Hello @Community member​ 

the STM32F1, F2 and F4 use different communication interface than the newer series. Their HAL driver is not compatible with the MW. You can try to modify the MW to support the older series, it should be possible with some effort. However ST is not going to commit resources to that project, focus is on new product development.
