Dear Community,

I have some trouble getting the HID Keyboard on the F4 running. I can only find code examples for outdated libraries. Is there any current USB HID Keyboard HAL profile available? The only recent lib I can find is for Mouse/Joystick/Gamepad HID. Some current examples would be also very appreciated.What I want to achieve is to input strings and ALT-ASCII characters to the host via USB HID keypress including modifier keys.Thanks a lot for your help!Outdated Examples:

Hi paul007,

In the STM32CubeF4 package, you may find a HID example in this folder: STM32Cube_FW_F4_V1.10.0\Projects\STM324xG_EVAL\Applications\USB_Host\HID_Standalone.It is a typical application on how to use the STM32F4xx USB OTG Host peripheral to interact with an USB HID Device such as a Mouse or a Keyboard.You can also get more details on the HID class used to access the mouse or keyboard referring to

Hi Mayla,

thanks for your reply. The examples you are mentioning are referring to the MCU being a host. However I'd like the MCU to be a keyboard (device). As far as I can tell, there is no Keyboard HID Profile in the Cube HAL. I'm looking for references to how or where someone implemented something like that.- Paul
