I need to create a GUI using WxPython in the form of a Speedometer to display 9 different data values fetched from Adafruit IO. My code is shown below:

This code does what it is meant to do nicely. However, it hangs quite often and then updates the values after a while. Is there any way I can optimize it further?

    This code does what it is meant to do nicely. However, it hangs quite often and then updates the values after a while. Is there any way I can optimize it further?

      I need to create a GUI using WxPython in the form of a Speedometer to display 9 different data values fetched from Adafruit IO. My code is shown below:

      app = MyApp(False)
      app.MainLoop()


      This code does what it is meant to do nicely. However, it hangs quite often and then updates the values after a while. Is there any way I can optimize it further?

      I need to create a GUI using WxPython in the form of a Speedometer to display 9 different data values fetched from Adafruit IO. My code is shown below:
