GPIO irq callback problem

[Luit]

Hi, I have exactly the same problem as described in viewtopic.php?f=11&t=2583.

Here is my main.py:

import machine
import urequests
from machine import Pin


def pincb(pin):
url = "(my test url)"
params = { "test": "true" }
urequests.urlopen(url, "GET", params)

p_out = Pin('GP2', mode=Pin.OUT)
p_out.value(1)
pin_int = Pin('GP1', mode=Pin.IN, pull=Pin.PULL_UP
pin_int.irq(trigger=Pin.IRQ_RISING, handler=pincb)


I know that the handler works perfectly, because I tested it with telnet and my website's access logs. But for some reason when I connect GP2 and GP1 the red light starts to blink rapidly for a couple of seconds. After that nothing happens when I connect the two pins until I restart the WiPy.

Testing a function from the REPL doesn't prove it will work as an interrupt handler. I suggest you read http://docs.micropython.org/en/latest/esp8266/reference/isr_rules.html.

The way to proceed is to have the interrupt handler set a flag which is tested in a main loop which runs forever. When the flag is set the main loop calls your handler and clears it.
