Hi,

In-fact I tried asking query through service request. The website portal seems to be very slow. I am not sure whether it got submitted or not.

So I am asking the query directly to you here. Please help me in addressing this query :

Hi,

We are using STM32H753xI in our design and we would like to use OTG_HS interface.

Our plan is to connect the OTG_HS signals (DP, DM, VBUS, ID) to micro USB connector.

The query is CAN WE CONNECT KEYBOARD AND MOUSE to the OTG_HS interface? We may run OS in microcontroller and we will view it through LCD interface. By connecting Keyboard/mouse we want to give inputs to OS. Is it possible to achieve this requirement using OTG_HS interface?

Hope I made my query clear to you. Please respond ASAP.

Regards,

Vijetha

Hi

‌,

You have to use the HID class. Some examples are already available in the STM32CubeH7 package and can be used to interface with a mouse or a keyboard.

Have a look toSTM32Cube_FW_H7\Projects\STM32H743I_EVAL\Applications\USB_Host\HID_Standalone. The file readme.txt describes the example and how to test it.

You can also build your own project depending on your application's requirement based on STM32CubeMX.
