how run IRQ() IN IRQ()

[jimmo]

pin_starter= Pin(5 ,Pin.IN ,handler = enter_password() ,trigger = Pin.IRQ_RISING)

You need to not have the "()" after enter_password.

Code: Select all

pin_starter= Pin(5 ,Pin.IN ,handler = enter_password ,trigger = Pin.IRQ_RISING)

(Otherwise this is the same as using the `irq` function later.

The second irq is always active and calls the callback function with a knock detection

Yes. That's how it works - once you register an IRQ, it is always active. You should only do this once.


I'm sorry this isn't an easy problem you're trying to solve.

Can you start with a simpler problem. For example, forget about IRQs, just write a program that counts the number of times a knock has happened. It will look something like:

Code: Select all

num_knocks = 0
knock_pin = Pin(5, Pin.IN)
while True:
  # Look at the pin value and see if it's changed.
  # If it has, add one to the counter and print it out.

like this ????

Code: Select all

def new_enter_password():
    door_password=""
    knock_count = 0
    from machine import Pin
    p5 = Pin(5, Pin.IN)
    for i in range(5):
        knock_count = 0
        print("range %i"%i)
        chk_time = utime.time() + 10
        while utime.time() <= chk_time:
            if p5.value()==1:
                knock_count += 1
                print(knock_count)
        door_password += str(knock_count)
        print("door password = " + door_password)
    print("end")

Code: Select all

def new_enter_password():
    door_password=""
    knock_count = 0
    from machine import Pin
    p5 = Pin(5, Pin.IN)
    for i in range(5):
        knock_count = 0
        print("range %i"%i)
        chk_time = utime.time() + 10
        while utime.time() <= chk_time:
            while p5.value()==1:
                knock_count += 1
                print(knock_count)
        door_password += str(knock_count)
        print("door password = " + door_password)
    print("end")

result very bad .Counters were counted most of the time
by one knock count is 4536 .

i use sleep time for fix .not work

Code: Select all

def new_enter_password():
    door_password=""
    knock_count = 0
    from machine import Pin
    p5 = Pin(5, Pin.IN)
    for i in range(5):
        knock_count = 0
        print("range %i"%i)
        chk_time = utime.time() + 10
        while utime.time() <= chk_time:
            if p5.value()==1:
                knock_count += 1
                print(knock_count)
                utime_sleep(1)
        door_password += str(knock_count)
        print("door password = " + door_password)
    print("end")

main and enter_passwort >> main function
is ok but Sometimes the amount of the starter is not zero and remains running
