USB CDC in STM32H563

VKoen.1 · ‎2024-09-10

tried to set up a USB device serial emulation (CDC) for STM32H563. Started a Free RTOS based project project in STM32CubeMX. But there I only can activate USB as "device_only in the "connectivity" segment but do not find any other USB related settings. I did that previously with the stm32F series and there it was in STmCube, no prob.

The generated code also seems not to have the USBD_DESC_Private_Defines or similar things needed.

Is it somewhere hidden under another name in STM32Cube? Or does STM32Cube does not support it? Or is this CPU issue? Or do I need to somehow get me drivers from other places and when yes, from where?

Hi @VKoen.1

Which USB stack do you want to implement? If you are using ST Library stack, it is not implemented in CubeMX. You can check examples provided here.STMicroelectronics/stm32h5-classic-coremw-apps: Provide a set of applications for STM32H5xx series based on the STM32 Classic Core Middleware libraries.
