Compilation Error Due to stm32h5xx_util_i3c.h Missing USE_FULL_LL_DRIVER Flag Protection

[vaa2ovr]

In the STM32H5 HAL, the file stm32h5xx_util_i3c.h was not included in the compilation list because it does not contain protection with the #if defined (USE_FULL_LL_DRIVER) flag, even though it uses the LL driver. This absence of protection results in a compilation error when the USE_FULL_LL_DRIVER flag is not defined.

Steps to Reproduce:

1. Attempt to compile a project that references stm32h5xx_util_i3c.h without defining USE_FULL_LL_DRIVER.
2. Observe the compilation failure due to missing flag protection in the file.

Suggested Solution:
Add conditional compilation protection around the code in stm32h5xx_util_i3c.h using #if defined (USE_FULL_LL_DRIVER). This would prevent compilation issues when the full LL driver is not in use.

Hello @vaa2ovr and welcome to the ST Community.

I've been able to reproduce this behavior. As a temporary workaround, you can copy the stm32_util_i3c.h from "STM32Cube_FW_H5_V1.3.0\Drivers\STM32H5xx_HAL_Driver\Inc to the " to the "Drivers/STM32H5xx_HAL_Driver/Inc/" of your project. I will report this for correction on the future (under internal ticket number 196105). 

Update: this issue has been solved on the STM32CubeMX V6.13.0.

Best Regards.

Thanks, the workaround works for me!
