I am interested to create a GUI for a data acquisition system (micro controller unit). I want to set a voltage at PV1 and measure the same voltage at A1 for checking purpose. The python script is given below:
# Establish the connection
import eyes17.eyes
p = eyes17.eyes.open()
# Setting the voltage at PV1
p.set_pv1(4)
# Read the voltage A1
VA1=p.get_voltage('A1')
print (VA1)
How can I create the GUI using PyQt5 and Qt Designer?
You can use the following manual as an example https://doc.qt.io/qtforpython-6/tutorials/basictutorial/uifiles.html
Follow these steps:
1. Design the UI using Qt Designer:
- Open Qt Designer and create a new form.
- Add the necessary widgets to the form, such as a label, a spinbox (or a slider) for setting the voltage at PV1, a label for displaying the voltage at A1, and a button to update the voltage reading.
- Save the UI file (e.g., `data_acquisition.ui`).
2. Convert the UI file to a Python script:
- Open a terminal or command prompt and navigate to the directory where you saved the UI file.
- Run the following command to convert the UI file to a Python script:
```
pyuic5 -o data_acquisition_ui.py data_acquisition.ui
```
- This will generate a Python script named `data_acquisition_ui.py` that contains the UI elements and their properties.
3. Create the main Python script:
- Create a new Python script (e.g., `main.py`) and import the necessary libraries:
```python
import sys
from PyQt5.QtWidgets import QApplication, QMainWindow
from data_acquisition_ui import Ui_MainWindow
import eyes17.eyes
```
- Create a `MainWindow` class that inherits from `QMainWindow` and the `Ui_MainWindow` class:
```python
class MainWindow(QMainWindow, Ui_MainWindow):
def __init__(self):
super().__init__()
self.setupUi(self)
self.p = eyes17.eyes.open()
self.updateButton.clicked.connect(self.update_voltage)
def update_voltage(self):
# Setting the voltage at PV1
self.p.set_pv1(self.voltageSpinBox.value())
# Read the voltage A1
VA1 = self.p.get_voltage('A1')
self.voltageLabel.setText(f"Voltage at A1: {VA1:.2f} V")
```
- In the `update_voltage` method, you can set the voltage at PV1 using the value from the spinbox (or slider) and then read the voltage at A1, updating the label with the measured value.
- Create the application and run the main window:
```python
if __name__ == "__main__":
app = QApplication(sys.argv)
window = MainWindow()
window.show()
sys.exit(app.exec_())
```
4. Run the application:
- Open a terminal or command prompt, navigate to the directory where you saved the Python scripts, and run the following command:
```
python main.py
```
- The GUI should appear, and you can interact with it to set the voltage at PV1 and display the measured voltage at A1.
Caution: Make sure to have the `eyes17` library installed and the necessary hardware (microcontroller unit) connected to your computer before running the application.
Hope it helps!
