Bases: object

Barcode scanner that returns one barcode per terminated serial line.

This class is intended for scanners configured as RS-232 or USB virtual COM devices. It reads bytes from pylabrobot.io.Serial until a configured line terminator is seen.

Methods

__init__([port, vid, pid, baudrate, ...])

read_line([timeout])

Read one barcode line from the serial stream.

reset_input_buffer()

Clear unread bytes buffered by the serial transport.

scan_barcode([read_time, symbology, ...])

Scan one barcode from the serial stream.

setup()

Connect to the scanner's serial port.

stop()

Disconnect from the scanner's serial port.

write(data)

Write raw bytes to the scanner.
