Description

Thank you shared this impressive project, I used the version:2.3.7 umodbus code, when run this code, the error shows: TypeError:extra keyword arguments given. Follow as code: `# modbus master driver for lidar

Same thing, can't find what cause the problem nor fix it so far.

My code for Pyboard v1.0:

from pyb import Pin
Y1 = pyb.Pin(pyb.Pin.board.Y1, pyb.Pin.OUT)
Y2 = pyb.Pin(pyb.Pin.board.Y2, pyb.Pin.IN)

# self defined package
from umodbus.serial import Serial as RTUMaster


rtu_pins = (Pin('Y1'), Pin('Y2'))
host = RTUMaster(
            pins = rtu_pins,
            uart_id = 6,
            baudrate = 9600,
)
