dear All,

as we know there is not possible to configure and code STM32F4 SMBus with Cube HAL drivers.

is it possible to do that manually?

Hello @KSzcz​ ,

You'll probably get help from the SMBUS examples within Cube firmware packages as:

 STM32Cube_FW_L0_V1.11.0\Projects\STM32L073Z_EVAL\Examples\SMBUS

 STM32Cube_FW_F3_V1.10.0\Projects\STM32303E_EVAL\Examples\SMBUS

The examples show how to ensure SMBUS Data buffer transmission and reception with IT.
