Member Function Documentation

◆ getClass()

std::string_view openmsx::Y8950KeyboardDevice::getClass ( ) const
finaloverridevirtual

A pluggable belongs to a certain class.

A pluggable only fits in connectors of the same class.

Implements openmsx::Pluggable.

Definition at line 5 of file Y8950KeyboardDevice.cc.

◆ read()

virtual byte openmsx::Y8950KeyboardDevice::read ( EmuTime::param  time)
pure virtual

Read data from the device.

Normally this are the keys that are pressed but you might also connect a non-keyboard device. A 0-bit means corresponding key is pressed 1-bit not pressed

Implemented in openmsx::DummyY8950KeyboardDevice.

◆ write()

virtual void openmsx::Y8950KeyboardDevice::write ( byte  data,
EmuTime::param  time 
)
pure virtual

Send data to the device.

Normally this is used to select a certain row from the keyboard but you might also connect a non-keyboard device. A 1-bit means corresponding row is selected ( 0V) 0-bit not selected (+5V)

Implemented in openmsx::DummyY8950KeyboardDevice.
