Sometimes it will be separate from the motherboard on an external bracket. This is often on the I/O panel on the back of PC motherboards. 3 Mother board back panel I/O with printer and serial ports.

This was also used on Arduino and Raspberry Pi with almost similar code.įig. The display can be connected directly or in my case through a serial interface I designed. In this case I'm controlling a stepper motor and a generic 2 line by 16 character Hitachi HD44780 LCD display. One can build or buy - buy could be far easier. 1 is my test setup consisting of my home built interface board. The parallel port supplies a complete bi-directional 8-bit port, five input pins, and four control output pins. This is real time hardware control using C under Linux. My purpose here is to build, test electronics including interfacing.
They are still used in industrial settings to control CNC machines.
While greatly upgraded in the early 1990s for my purposes I'm interested in computers built after 2000. It is also known as a Centronics port or printer port. Often known as a parallel port used from the 1970s though ~2008. I'll have more detailed pages on each subject.
