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.
recv(data, *, timeout=5000)¶
Receive data on the bus:
datacan be an integer, which is the number of bytes to receive, or a mutable buffer, which will be filled with received bytes.
timeoutis the timeout in milliseconds to wait for the receive.
Return value: if
datais an integer then a new buffer of the bytes received, otherwise the number of bytes read into
Send data over the USB HID interface:
datais the data to send (a tuple/list of integers, or a bytearray).
