Detailed Description

template<typename MANAGER>
class devices::mcp230xx::MCP23008< MANAGER >::ConfigureInterruptsFuture

Create a future to be used by asynchronous method configure_interrupts(ConfigureInterruptsFuture&).

This is used by configure_interrupts() to asynchronously launch the I2C transaction, and it shall be used by the caller to determine when the I2C transaction is finished.

Parameters

int_pins	each bit sets if the matching pin shall generate interrupts
ref	contains the reference value for comparison with the actual input pin; if input differs, then an interrupt will be triggered for that pin, provided that `compare_ref` for that bit is also `1`.
compare_ref	each bit indicates the condition for which the matching input pin can generate interrupts; if `0`, an interrupt is generated every time the input pin changes level, if `1`, an interrupt is generated every time the input pin level changes to be diferent than the matching bit.
