Interruption and Timer

[Pierre_GS]

Hi,

I have a problem with my interruption. So I have a function called by a timer like this :

Code: Select all

tim = Timer(1)
tim.init(period=300, callback=main)

and I have declared button interruption like this :

Code: Select all

pin_button_down.irq(trigger=Pin.IRQ_RISING | Pin.IRQ_FALLING,
                    handler=handle_button)
pin_button_enter.irq(trigger=Pin.IRQ_RISING |
                     Pin.IRQ_FALLING, handler=handle_button)
pin_button_up.irq(trigger=Pin.IRQ_RISING | Pin.IRQ_FALLING,
                  handler=handle_button)
pin_button_escape.irq(trigger=Pin.IRQ_RISING |
                      Pin.IRQ_FALLING, handler=handle_button)


def handle_button(Pin):
    """Function called when a button is pressed"""

    global button_interruption_treated, button_unpressed, coeff_speed_button_incrementation

    if button_unpressed or Pin.value() == 0:
        myprint("pressed")
        treat_button_interruption()
        button_interruption_treated = True
        button_unpressed = False
    else:
        print("unpressed")
        coeff_speed_button_incrementation = 0
        button_unpressed = True

My problem is that my main function called by the Timer take time and button interruption don't take the advantage on my main funtion so interruption are invisible.

Do you have any suggestion about what I have ?

Thank you
