Detailed Description

template<typename MANAGER>
class devices::mcp230xx::MCP23017< MANAGER >::BeginFuture

Create a future to be used by asynchronous method begin(BeginFuture&).

This is used by begin() to pass input settings, and it shall be used by the caller to determine when the I2C transaction is finished, hence when you may use other methods.

Parameters

mirror_interrupts	if true then INTA and INTB are mirrored, hence any interrupt occurring on A or B port will generate a level change on both pins; hence you can connect any pin to only one interrupt pin on Arduino if you are lacking available pins.
interrupt_polarity	the level triggerred on INTA or INTB pin when an interrupt occurs
