I would like to know , how to configure STM32H7 using STM32CubeIde with USB_OTG_FS . IS there any example projects?

Hi JTiru.1,

You can download STM32CubeH7, there are several USB projects in this directory: \Projects\Board_Name\Applications\USB_Device\ for USB device projects or Projects\Board_Name\Applications\USB_Host\ for USB Host projects.

You can learn how to create an STM32CubeIDE project based on STM32CubeMX from here.

And here is an example about how to create USB device project with STM32CubeMx.

Regards,

Ons.
