Using a PCs parallel port for more than printers ele. HOME. ELECTRONICS MAIN PAGE. ELECTRONICS PROJECTS CONTENTS Bookmark this on Delicious. Recommend to Stumble. Upon. Using a PCs parallel port for more than printers. This material is about the parallel port on MS DOS Windows. It sometimes spills over into things of more general. In a moment, I am going to ask you to consider if the parallel port is really the way you want to go, and suggest alternatives. PLEASE NOTE You CAN damage your computer if you make ill advised. Any use you make of anything you find here must be. AT YOUR OWN RISK. I have designed a parallel port protector that may be of interest. Click on the link for information, and a way to obtain the circuit diagrams. For a free turn parallel port pins onoff program, which works with Windows XP and other Windowses, I think check out my page about Sheepdog. Curtain. Closer. Also, as part of my Delphi tutorials website, I have posted another small app to turn individual pins of the parallel port on or off. You can download the. The app is in the. Delphi programmer to use it. But you do need to put both the app DD7. Inp. Out. 32. dll in some folder on your system. They should be in the same folder. For any I Want It Now merchants A good site with essentials, minimal warnings, fewer details. Not written by me. Opens in new tab, so you can come back here if disappointed. Table of Contents, Parallel Port Use. A few odds and ends. Alternatives New ways to do the things we did with the parallel port in the Good Old Days. How to send and receive data to from the parallel port. You can defy Bill Gates and send receive data even on a Win. NT or XP machineWhich pins both back of computer and end of cable have which signals. Help on the software issues, with Basic, Pascal and Delphi addressed. Help connecting an LED, for the complete beginner. Opens in new tab. Help with inputs and outputs, for beginners. Help with the issues of load limits, pull ups, pull downs. USB or the serial COM port Notes on interfacing. USB Parallel Port Adapter Fine for printer, maybe. AND a way to email me, for whatever Ive missed Odds and ends. Before we get to the parallel port stuff, two ads from our sponsors. If you are going to use this page, you are probably not a computing novice. Ever set up a web server It isnt hard If you have an always on broadband connection, Far. Watch may be of interest. I have written pages for you explaining how to use an old Win. Win. 98 box is at from anywhere on the internet. Nothing to buy And if you connect something to that PC via its parallel port, you can see the state of the inputs to the parallel port from afar, too. If you would be willing to help bring this information about the parallel port to a wider readership, please check out my plea for translators Dont want to tie up your printer port No excuse You can get a cheap card to provide a second parallel portAlternatively, for some projects needing input only consider using your joystick port. N. B. Most joystick ports do not sense analogue voltages. For how to program Delphi 2 and higher to read joysticks visit this page of my Delphi Tutorials. Using your PC isnt the only way to have a lot of fun with controlling and sensing external devices, for example the Arduino, an inexpensive programmable microcontroller, which is itself open source, and which has excellent free, open source development hardware. Control Plus once sold a neat little Pascal based microprocessor system, and they offered a free simulator. If you hear of that being available again, please tell me If for some reason you dont like the Arduino, there are alternatives. Dont let the warning above worry you too much. I want to stress that there is a lot of fun to be. Find yourself an antique PC. If you. cant rescue one from a dusty corner, you can buy one for almost. You can use the same monitor as you use on your main. If you wreck the antique, it hasnt cost you much I got one, with monitor, off a sidewalk once. I have a third generation inexpensive protect the computer circuit. You interpose it between your PC and the home made stuff you are attaching to. Inputs to the computer are passed through an opto isolator, outputs are fed to the coils of relays. Properly set up, the worst thing you can do is wreck an opto isolator or a relay. Email me if you are interested in that device. If you can design and etch your own PCBs I can send you some notes. Send me a snailmail address, as they are not available in machine readable form. If you are not making your own PCBs, I may still be able to help, but not so quickly and not for free. If you are very new to the hardware side of computing, my Connect An LED In Words Of One Syllable may be of interest. Alternative ways to have the fun we used to have via the parallel port. If you are sure you just want to know how to do it with a parallel port, without considering the alternative connection paths, you can skip over this alternatives section. Once Upon A Time. PC. Many of us started with LEDs or even incandescent bulbs. WAS a time before LEDs. Then there were push buttons. And once you got started, the sky was and is the limit. Theres a saying The hard part is thinking of what you want to do. In other words, the hard part is finishing Id like to make the computer control read. It is still quite possible to do these things. If you are just getting started, I would advise you to consider other ways of doing the things we used to do via the parallel or serial port. They wont be suitable for all of you, nor for all projects, but at least consider them. And when Ive listed them, I will go on to talk in detail about how to use the parallel port, for those who want or need to do it that way. You can now 2. 01. I particularly like the Arduino, but there are many alternatives. I have an Arduino specific page which you can access from the microprocessors page there is a link to above. Once you master the basics. Arduino, or similar system the way we used to use a PC and its parallel port. Life becomes fun again, instead of being work. Once upon a time, I had a whole PC tied up just to run a burglar alarm at my house. Now the same work can be done with an Arduino. The Arduino costs MUCH less, uses less electricity, is more tolerant of the occasional power failure. Another cool possibility You can connect one or more PC using the Dallas Microlan, aka 1 wire. Look at the DS2. 40. Or, give my introduction to 1 Wire a try. Extra cool The ports would interface to your computer via provided by others software running through either your serial port or your USB port You still have to access the software that accesses the ports, but a lot of the overhead of the communications with the port is taken care of for you. The bad news You need to equip your PC with a pc to Micro. Lan adapter about 2. The data rates wouldnt be as high as they could be via a PCs parallel port. You will need more advanced programming skills to use the 1 Wire answer. Digital IO over a LAN, or even over internet We are now moving into a more expensive and less flexible realm, but there are ways to have digital IO pins what a parallel port gives you connected to a PC across a LAN that the PC is part of, or even across the internet, if you are willing able to set up a server near the device with the IO pins. I dont have extensive information for you in this area, but I do have some. See my pages starting with Sensing and Control across networks. Theres also my Far. Watch system, which is not expensive, for what it does, but doesnt offer you all the possibilities of what you can do via the parallel port. Far. Watch is mainly for monitoring premises from afar. You can even have graphs of the state of the monitored phenomena. The Arduino, already mentioned, is one way into the delightful world of digital electronics.
