Member Function Documentation

read()

virtual uint64_t AnalogMultiplexerInput::read ( uint64_t lastState )

overridevirtual

Read the current state of the inputs (pressed or released)

Warning

This function must not set any bit outside of the input bitmask in the return value.

Parameters

lastState

State of the same inputs as recorded in the previous iteration. Whether the current state is unknown, lastState must be returned (properly masked). Must be set to zero at first call.

Returns

uint64_t Current state of the inputs (a bit set to 1 means a pressed button).

Implements DigitalInput.
