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.
