minimalmodbus

问题 I am working on a automation test case for a system and need a automated modbus input device. My use case here is to implement a Raspberry pi based RTU modbus slave and connected to a modbus master. I want this raspberry pi based slave to populate and send a response to master when ever master requests for a register value. I am new to this protocol and environment, I am not able to find any python script or libraries where we have a modbus slave client. I came across this below Serial python

问题 I have made a Tkinter program that reads from a modbus slave device. Every second it reads the device and displays the output onto labels. However, I have multiple tabs that run the same code for each device connected. While a device is being read, the whole GUI freezes so you can't move the program or press buttons until it is done reading. Would multiprocessing help with freezing? If so, how could I implement it? Here is my code: import tkinter as tk from tkinter import * from tkinter
