Listeners lost when instantiating multiple RotaryIRQs

[jphalip]

Hi,

I'm having issues with the following sample code:

aaa = RotaryIRQ(
    pin_num_clk=26,
    pin_num_dt=27,
    min_val=0,
    max_val=10,
    reverse=True,
    range_mode=RotaryIRQ.RANGE_WRAP)

aaa.add_listener(lambda: print('aaa'))

bbb = RotaryIRQ(
    pin_num_clk=26,
    pin_num_dt=27,
    min_val=0,
    reverse=True,
    range_mode=RotaryIRQ.RANGE_UNBOUNDED)

bbb.add_listener(lambda: print('bbb'))

(Note: I'm using the same physical encoder with the same pins, but with otherwise different parameters. Also, I'm using a Raspberry Pi Pico with the latest version of Micropython.)

I would expect to see both aaa and bbb printed every time I move the rotary encoder. However, only bbb gets printed.

In other terms, it looks like instantiating a second RotaryIRQ causes the first one to lose its listeners.

Is that a bug or am I missing something?

Thanks,

Julien
