class USB_HID -- USB Human Interface Device (HID)
=================================================
The USB_HID class allows creation of an object representing the USB
Human Interface Device (HID) interface. It can be used to emulate
a peripheral such as a mouse or keyboard.
Before you can use this class, you need to use :meth:`pyb.usb_mode()` to set the USB mode to include the HID interface.
Constructors
------------
.. class:: USB_HID()
Create a new USB_HID object.
Methods
-------
.. method:: USB_HID.recv(data, *, timeout=5000)
Receive data on the bus:
- ``data`` can be an integer, which is the number of bytes to receive,
or a mutable buffer, which will be filled with received bytes.
- ``timeout`` is the timeout in milliseconds to wait for the receive.
Return value: if ``data`` is an integer then a new buffer of the bytes received,
otherwise the number of bytes read into ``data`` is returned.
.. method:: USB_HID.send(data)
Send data over the USB HID interface:
- ``data`` is the data to send (a tuple/list of integers, or a
bytearray).
