MCP23017 interrupts. #13

Closed ErikParso closed 5 years ago

Allow users to enable interrupt pins intA and intB. Mirroring is also optional.

hiya we don't have anyone maintaining this code at this time - did you test this on hardware :)

ErikParso commented 5 years ago

Hello i tested it on single MCP23017 with input (button) on multiple input pins (A also B). Interrupt was working fine. IntA pin is connected to GPIO17 (raspberry pi3). On button push my code is notified 2 times (falling and rising edge). I also tested mirroring when both intA and intB is signaling any input change.
