Hi @ll,

I'd like to use a STM32F4xx based board + NuttX to emulate an USB keyboard.
According to the NuttX website there should be some kind of USB device support for HID?
(Maybe I misunderstood it?)

However I can only find a host driver for HID keyboard but no USB device driver!

Did I overlook it?

Thanks!

No, you did not overlook anything. That are no implementations of any USB HID device in drivers/nuttx/usbdev.

oh... a real pity!

Are there any plans for that?
It's mentioned here: http://www.nuttx.org http://www.nuttx.org/ under USB device support... or is this just a copy&paste error?

Yes, a copy-paster error. Thanks for noting that.


I have no plans for an HID USB devices.

For what it's worth I am going to (slowly) work on a nuttx app to translate GPIO/button presses that are morse code into a USB HID keyboard device on nuttx. Was thinking I might use v-usb library in some fashion (for AVR microcontrollers though). https://github.com/obdev/v-usb https://github.com/obdev/v-usb

I plan on using stm32f103.


I'll post here if I make any progress.

Hi Craig,

This project you cited is GPL so you cannot use it as base.

I suggest you to take a look at LUFA Library.

BR,

Alan
