Overview

********
|
|
|
|
|
|
|
|
|
|
This sample app demonstrates use of a USB Human Interface Device (HID) driver
|
|
|
|
|
by the Zephyr project. This very simple driver is enumerated as a raw HID
|

device. This sample can be found under :zephyr_file:`samples/subsys/usb/hid` in the
|

Building and Running
|
|
|
|
|
********************
|
|
|
|
|
|
|
|
|
|
This sample can be built for multiple boards, in this example we will build it
|
|
|
|
|
for the quark_se_c1000_devboard board:
|
|
|
|
|
|
|
|
|
|
.. zephyr-app-commands::
|
|
|
|
|
:zephyr-app: samples/subsys/usb/hid
|
|
|
|
|
:board: quark_se_c1000_devboard
|
|
|
|
|
:goals: build
|
|
|
|
|
:compact:
|
|
|
|
|
|
|
|
|
|
After you have built and flashed the sample app image to your board, plug the
|
|
|
|
|
board into a host device, for example, a PC running Linux.
|
|
|
|
|
The board will be detected as shown by the Linux journalctl command:
|
|
|
|
|
|
|
|
|
|
.. code-block:: console
|
|
|
|
|
|
|
|
|
|
$ journalctl -k -n 10
|
|
|
|
|

|
|
|
|
|

|
|
|

You can monitor report sending using standard Linux ``usbhid-dump`` command.
|
|
|
|
|
|
|
|
|
|
.. code-block:: console
|
|
|
|
|
|
|
|
|
|
$ sudo usbhid-dump -d 2fe3:0100 -es
|
