Missing method Pin.irq on fw 1.6.3.b2

[claudyus]

Hi all,
I'm using a lopy board with fw versione 1.6.3.b2 and micropython version v1.8.6-464-g0f843911 on 2017-02-17

I would like to use Pin irq and in some old fw version the method was present but now it appear to be missed.

>>> Pin.
init            value           toggle          id
mode            pull            hold            callback
module          exp_board       IN              OUT
OPEN_DRAIN      PULL_UP         PULL_DOWN       IRQ_FALLING
IRQ_RISING      IRQ_LOW_LEVEL   IRQ_HIGH_LEVEL

Any hit to solve this?
Someone can kindly provide and old fw version where pin interrupts are working?

Pin interrupts are done via pin.callback(trigger, handler=None, arg=None)
Check the Pin manual for details https://docs.pycom.io/pycom_esp32/library/machine.Pin.html
