Serial Port Monitor Code Example – Python with Tkinter

In this article, we will provide a code example for a serial port monitor using Python with Tkinter. Tkinter is a popular GUI toolkit for Python that allows developers to create user interfaces for their applications. With Tkinter, we can easily create a simple and effective serial port monitor for our Python applications.

Code Example

Below is a simple example of a serial port monitor using Python with Tkinter:

“`python
import tkinter as tk
import serial

# Create a new Tkinter window
window = tk.Tk()
window.title(“Serial Port Monitor”)

# Create a text widget to display the serial data
text_widget = tk.Text(window)
text_widget.pack()

# Open the serial port
ser = serial.Serial(‘COM1’, 9600)

# Function to read and display serial data
def read_serial():
while True:
data = ser.readline().decode(‘utf-8’)
text_widget.insert(tk.END, data)

# Create a button to start reading the serial data
start_button = tk.Button(window, text=”Start Reading”, command=read_serial)
start_button.pack()

# Run the Tkinter event loop
window.mainloop()
“`

In this code example, we create a new Tkinter window and add a text widget to display the serial data. We then open the serial port using the `serial` library and create a function to read and display the serial data. Finally, we create a button to start reading the serial data and run the Tkinter event loop to start the application.

Conclusion

With this code example, you can easily create a serial port monitor using Python with Tkinter. This can be a useful tool for debugging and monitoring serial communication in your Python applications. Feel free to customize the code to fit your specific needs and requirements.
