Bug Fix 1: The "No coins added! Please add coins first" was invoked on a key press and then invoked alternately with the start screen without stopping. With this fix, the page is only called once.
Bug Fix 2: The "GPIO.add_event_detect" function is used for the GPIO.BCM input 5 and 6. These processes then run in the background parallel to the main program. These processes must also be stopped again if the program is ended with "except KeyboardInterrupt" , otherwise there will be overlaps and the bouncing phenomenon during a soft start.
Changed the order of button actions so that the severity of the action is increasing. The "wallet reset" is fatal and comes at the very end. 1 : Shows screen: "No coins added! Please add coins first" 3 : Simulates adding a coin (2 coin pulses, only for testing) 5 : Shutdown the host machine 7 : Reset Wallet (!!!) an scan new wallet credentials with camera
If FIAT was paid in, the button may only have one function => "Start withdrawal prozess". It doesn't matter how many times the key was pressed in a row.
Update logger.info("Restriction for the button => Set pulses = 1")
