INT[AB] handling and external I2C object

runout-at commented 3 years ago

Hi & thanks for the great work!

I was in need of using the interrupt functionality of the chip and be more compatible with machine.Pin. If anybody is interested I could publish the code - let me know.

New functionality:

Pin class like machine.Pin
Using INT[AB] pins (mirrored) like machine.Pin.irq() with callback

Changed constructor:

An I2C object is given instead of sda/scl-pins like in the module for ads1x15 to have just one central I2C object
New argument for config of mcp230xx features like providing a machine.Pin object where the INT[AB] of the mcp230xx is wired to on the esp8266

the handling of irq and callbacks is not tested yet. feedback is welcome in the issue tracker on gitlab. the intention is to have a compatible interface to machine.pin.
