I see there are two methods to handle Interrupts. ExtInt and irq. Which one should I choose?

Modem_Status_LED=ExtInt(Pin('G1'), ExtInt.IRQ_RISING_FALLING, Pin.PULL_DOWN,callback)
Power_Status_LED=ExtInt(Pin('G0'), ExtInt.IRQ_RISING_FALLING, Pin.PULL_DOWN,callback)

Code: Select all

>>> p0.irq(trigger=Pin.IRQ_FALLING, handler=callback)
>>> p2.irq(trigger=Pin.IRQ_RISING | Pin.IRQ_FALLING, handler=callback)

This boils down to which library to use, pyb (with ExtInit) or machine (with Pin.irq()). In my view there is no satisfactory answer. The intention is that machine will become the standard across all ports, replacing the Pyboard specific pyb. However in its current state of development machine only supports a subset of the functionality of pyb. The choice is yours. You can, of course, mix and match
