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 pyb.usb_mode()
to set the USB mode to include the HID interface.
Methods¶
- 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 intodata
is returned.
- 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).
