Conditional Button Press

[Raudert]

This is a tkinter button press. So GUI, a simple Stop button to end the loop. Here is the exact code I am working with.

 

  def callback():
       while True:
           ADC_Value = adc.read_adc_difference(0,gain = GAIN)
           print(ADC_Value, "ADC Value")
           sleep(2)
           x_Input = (((ADC_Value-68)*(1/8002.0))*(1/2.4))-0.25
           print(x_Input, "Current Pressure")
   t = threading.Thread(target = callback)
   t.start()

This would probably solve itself if I could find the tkinter library in my directory.
