+Sure, I can guide you through creating a Python script that fulfills your requirements using Tkinter for the GUI and a serial library for communication. Here's a basic outline of the steps we'll take:
|
|
|
+
|
|
|
+ Create a Tkinter GUI with buttons for start, stop, and save.
|
|
|
+ Use the serial library to communicate with your device.
|
|
|
+ Start reading data when the start button is clicked.
|
|
|
+ Stop reading data when the stop button is clicked or when 10,000 sample points are reached.
|
|
|
+ Save the data to a CSV file when the save button is clicked.
|
|
|
+
|
|
|
+Let's start by creating the script:
|
|
|
+
|
|
|
+python
|
|
|
+
|
|
|
+import tkinter as tk
|
|
|
+from tkinter import filedialog

+import csv

|
+
|
|
|
+ self.serial_port = "COM1" # Change this to your serial port
|
|
|
+ self.baud_rate = 9600 # Change this to match your device's baud rate
|
|
|
