How to build a USB HS and USB FS with my own shield for communication with the PC?

[VTodm.1]

As i am new to building my own Microcontroller shield , i want some help ! I want to achieve a high speed USB connection with PC to transfer data from micro controller to PC .

Now Do i need a external peripheral with the micro to get the HS connection? HS connection seems to have a lot of pins. The micro controller i am using is STM32H755BIT3 ! Thanks

For USB HS you normally need an external ULPI-PHY and some ESD protective devices as an interface between the ULPI of the STM32 and the USB port (see e.g. the schematics of the STM32H747I-DISCO).

There is also some software example available for an MSC_Standalone in the repository, either on Github or the local repository downloaded with STM32CubeMX oder STM32CubeIDE.

Good luck!
