问题 i have a serial app, The Robot class need to always receive serial message and then to do some thing, the Demo gui need to interactive Robot and get Robot.handle_readData , if no data get, need to get again and again until had data. Now i had no idea how to solve this problem, need someone give me good idea. from PyQt5.QtWidgets import * from PyQt5.QtCore import * from PyQt5.QtGui import * from PyQt5.QtSerialPort import * class Robot(QObject): def __init__(self): super().__init__() self

问题 This question already has answers here : Connect to serial from a PyQt GUI (2 answers) Closed 18 days ago . My goal is to create a GUI using PyQt5 with functionality to receive data from serial port. This data should be printed into text browser inside the GUI. Data should be printed there continuously. Reading should be toggled by pushing button. This is the GUI part of the code: class Ui_MainWindow(object): def setupUi(self, MainWindow): MainWindow.setObjectName("MainWindow") MainWindow

问题 I have a problem with the gui data, my gui doesn't update a real-time value when I click the button. the first time i click my connect button it shows the correct value, but when i change the sensor position, it doesn't update the value. Where i miss the code, i try to solve the problem from the other similar question to this question, but still does not solve my problem here is my code class SerialReadThread(QThread): received_data = pyqtSignal(QByteArray, name="receivedData") def __init__

问题 Is there some way to be notified when my serial device is ready to receive more data? I am implementing a program that feeds commands to a servo controller over serial using the asynchronous API of QSerialPort. The program works, but it seems that I am experiencing congestion. In my application I keep a registry of most updated servo position that I wish to synchronize with the controller with as low latency as possible. My attempt at pushing new data to the serial port as quickly as time

问题 I am performing an app with QT for communicate my PC with an 8 bits microcontroller through rs-232. I am using the QtSerialPort library and the communication is working fine, but each time I write something from the PC to the micro and I receive the response, I have to close and open the serial port or I can't continue communicating.. My configuration is: 10500 bps, 8 bits, 1 stop, no parity, no flow control. The code used for the configuration and the lecture/writting of the port is the next
