nucleo-H755ZIQ mouse+keyboard simultaneous HID

[stefanoma76]

Dear All,

I'm trying to develop a USB HID mouse and keyboard both on the same USB connection for the nucleo-H755ZIQ board. I mean a complete project (from configuration in CubeMx) and software implementation for CubeIDE.

On the net I've tryed some example to emulate mouse and keyboard separately (one a time) and they work. But I'm not able to implement mouse and keyboard simultaneously on the same single USB connection.

My goal, at the moment, is software in which if I press the user button could move the mouse pointer and send a character as a keyboard.

Could somebody help me?

Best regards

This can be done in two ways: (1) composite device with two HID functions, (2) one HID device with two "top-level collections.  Method (2) needs less resources (only one USB interface and one set of end points) and should work with all decent hosts (Linux, Windows, MAC).

CubeMX generates a limited HID device code that you can improve, based either on the "legacy" ST USB device library or UsbX.

Here you can find help with understanding the examples and coding.
