How to modify an external interrupt?

[hansel]

Is there a way to modify an external interrupt (say map to a different callback)?
ExtInt has no deinit(), and when calling the constructor again for the same pin one gets an exception: ExtInt vector 1 is already in use

Code: Select all

def callback1(line):
    print ("cb 1")
def callback2(line):
    print ("cb 2")

pin = pyb.Pin.board.X1
irInt = pyb.ExtInt(pin, pyb.ExtInt.IRQ_RISING_FALLING, pyb.Pin.PULL_UP, callback1)
irInt = pyb.ExtInt(pin, pyb.ExtInt.IRQ_RISING_FALLING, pyb.Pin.PULL_UP, callback2)

The deinit is to set the callback to None.
