pymata与hc-hc 04 TypeError：‘模块’对象是不可调用的

Question

我正在使用带有超音速传感器的arduino uno和manjaro上的pyhon(pymata).I am，这可能没有用。我试图让它检测距离，但当我运行它时，出现了以下错误：“模块”对象不可调用。我使用的代码是：

from random import triangular

from tkinter import OFF, ON

import speech_recognition as sr

from pyfirmata import Arduino

from pymata4 import pymata4

import time

#used to check if the arduino port selected is the right one
#board = Arduino('/dev/ttyACM0')
#print(board.get_firmata_version())
#led = board.get_pin('d:10:o')
#red = 9
#blue = 8
#yellow = 5
trig = 10
eco = 11


board = pymata4.Pymata4()

board = pymata4(com_port='/dev/ttyACM0')
board = pymata4(arduino_wait=10)


def the_callback(data):
    print("Distance is: ", data[2])

board.set_pin_mode_sonar(trig, eco, the_callback)

while True:
    try:
        time.sleep(1)
        board.sonar_read(trig)
except Exception:
    board.shutdown()

Answer 1

这些线条是错误的：

board = pymata4.Pymata4()

board = pymata4(com_port='/dev/ttyACM0')
board = pymata4(arduino_wait=10)

pymata4是一个模块，因此出现了错误。

初始化board时，请使用以下语法：

board = pymata4.Pymata4( com_port='/dev/ttyACM0', arduino_wait=10)
