# This example tests all the timers.

# Note: functions that allocate memory are Not allowed in callbacks

    blue_led.toggle()

print("")

    try:
        print("Testing TIM%d... "%(i), end="")
        tim = Timer(i, freq=10)     # create a timer object using timer 4 - trigger at 1Hz
        tim.callback(tick)          # set the callback to our tick function
        time.sleep(1000)
        tim.deinit()
    except ValueError as e:
        print(e)
