USB Composite Design (CDC+HID Keyboard)

[FuadPurnomo]

Dear STM32 Advisor,

I'll design a system based on Nucleo 64 H533RE. The system will act as USB CDC and USB HID Keyboard at the same time. The idea is when the CDC receive a character, here for example "F" then the Nucleo H533RE will output a high going pulse. And, if the Nucleo H533RE receive falling pulse external interrupt, the the Nucleo H533RE will press the F8 key. As a beginner on STM32, is it possible?

Thanks and regards,

Fuad Purnomo.

The hardware is capable of doing that.

I recommend buying a nucleo board, getting the existing relevant examples working, then extending it to your use case.
