How to implement HID + CDC?

[HGaut.1]

Hello, I am actually trying to implement HID + CDC in my project, I found nothing interesting on Google.

Is someone know something about it or have a working example? It would help me a lot, thank you in advance.

Hello @HGaut.1​ ,

You can follow the instructions from the STM32 USB training:

• How to develop my STM32 USB based application?
• STM32 USB training - 09.7 USB HID device custom device lab

I recommend you to refer to the "STM32Cube USB device library" User manual UM173 and UM1720.

You can refer to the CDC_Standalone and HID projects available in the STM32Cube firmware related to your device.

The ready-to-use application can help you as an implementation example. 

Hope this helpful for you.

Thank you for your reply Imen.

What I want to do is implement both HID + CDC in 1 project to be able to send keyboard key through HID and data through COM PORT. (having a HID and COM PORT keyboard is my goal)

I tried on my own and with help on Google, but I found nothing interesting.
