Allow for disabling of Interrupts

[ghost]

There is only a function to enable interrupts per pin but none to disable interrupts.

Please offer functions to disable interrupt of a single pin or all pins altogether.

Yes, I agree. Ran into this too... Lost hours because a) MCP wasn't being reset when I was pushing esp8266 reset, b) I wasn't getting the correct interrupt pin and c) this function doesn't exist!

void Adafruit_MCP23017::disableInterruptPin(uint8_t pin) { // disable the pin for interrupt updateRegisterBit(pin, LOW, MCP23017_GPINTENA, MCP23017_GPINTENB); }

Okay, I never submitted a pull before. Hope I did it right, #54

Wow thanks for the quick integration! Sort of related: How do we feel about disabling all interrupts on begin()?

Closing. Fixed with #54.
