Member Function Documentation

getClass()

std::string_view openmsx::PrinterPortDevice::getClass ( ) const

finalvirtual

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 PrinterPortDevice.cc.

getStatus()

virtual bool openmsx::PrinterPortDevice::getStatus ( EmuTime::param  time )

pure virtual

Returns the STATUS signal: false = low = ready, true = high = not ready.

Implemented in openmsx::DummyPrinterPortDevice, openmsx::PrinterCore, openmsx::PrinterPortLogger, and openmsx::PrinterPortSimpl.

Referenced by openmsx::YamahaSKW01PrinterPort::getStatus(), openmsx::MSXPrinterPort::peekIO(), and openmsx::SVIPrinterPort::peekIO().

setStrobe()

virtual void openmsx::PrinterPortDevice::setStrobe ( bool  strobe, EmuTime::param  time  )

pure virtual

Sets the strobe signal: false = low, true = high.

Normal high, a short pulse (low, high) means data is valid.

Implemented in openmsx::DummyPrinterPortDevice, openmsx::PrinterCore, openmsx::PrinterPortLogger, and openmsx::PrinterPortSimpl.

Referenced by openmsx::MSXPrinterPort::plug(), openmsx::SVIPrinterPort::plug(), openmsx::YamahaSKW01PrinterPort::plug(), and openmsx::YamahaSKW01PrinterPort::setStrobe().

writeData()

virtual void openmsx::PrinterPortDevice::writeData ( uint8_t  data, EmuTime::param  time  )

pure virtual

Sets the data signals.

Always use strobe to see whether data is valid. As an optimization, this method might not be called when the new data is the same as the previous data.

Implemented in openmsx::DummyPrinterPortDevice, openmsx::PrinterCore, openmsx::PrinterPortLogger, and openmsx::PrinterPortSimpl.

Referenced by openmsx::MSXPrinterPort::plug(), openmsx::SVIPrinterPort::plug(), openmsx::YamahaSKW01PrinterPort::plug(), and openmsx::YamahaSKW01PrinterPort::writeData().
