Raspberry pi simpel coding

[mike3001]

You could add this two methods to your class StopWatch.

    def cb_start(self, channel):
        self.Start()
        
    def cb_stop(self, channel):
        self.Stop()

This two methods are called from outside by GPIO.add_event_detect.
The code which should setup the inputs and set the event detection.

def set_gpio(start_pin, stop_pin, start_cb, stop_cb):
    GPIO.setmode(GPIO.BOARD)
    GPIO.setup(start_pin, GPIO.IN)
    GPIO.setup(stop_pin, GPIO.IN)
    GPIO.add_event_detect(start_pin, GPIO.RISING, callback=start_cb, bouncetime=200)
    GPIO.add_event_detect(stop_pin, GPIO.RISING, callback=stop_cb, bouncetime=200)

Then add to Main after creation of a StopWatch instance, the set_gpio function call:

In Main():

stopWatch = StopWatch(root)
set_gpio(38, 36, stopWatch.cb_start, stopWatch.cb_stop)
stopWatch.pack(side=TOP)

Thank you, for youre respons :)
i have tryed youre code, but it will stil not work for me :/
