Hey fellow coders,

I'm interested in programming software for hardware components that are connected to the PC. Something like a LCD etc. just to start with, because I'm new to that kind of stuff.
So, I was wondering if you folks could give me some links where I can find Tutorials and references about this on the Internet.
I'm sure this might be useful to other programmers, too.

Thanks in Advance
Regards Olli

Hi Olli,

This is the type of thing I'm trying to do :alright: ... I've been researching it off and on for a year I guess now when every i get some free time. Anyways below I have listed a few links that I found interesting that I think you might too. Also I've included electronics links since I'd really like to build then program my own... Anyways here they are, enjoy!

// Microcontroller Information
Peter H. Anderson - Embedded Processor Control (Lots of links!!)
Reynolds Electronics
Stamps In Class (Makers of BASIC Stamp, Microcontroller edu resources for Basic Stamps)
Stampic Index?For Stamp Books
Very Cool thing I wanna try out (LCD to printer port)

// More Microcontroler Information
The EE Compendium - Electronic Engineering and Embedded Systems Programming
Roger's Embedded Microcontrollers Home Page

// Electronics information
Transtronics Home of Automation
Twisted Pair
Electronics Formulas and more
Ramsey Electronics

While the code contained within the pages of the below link is not in Assembly language it may be of interest/use to you.

lots of info about all kinds of ports.

lots of info about everything that has to do with electronics.

The first thing you'll need is some way to get information into and out of your computer. my prefered (and cheap!) way to do this is with an 8255 controller card. The cheaper versions of these install into an ISA expansion slot (one of the main reasons I keep my P233 around is it has lots of these slots).
Boonton Electronics has the cehapest I've seen ($59 kit), but JDR and Measurement Computing also have cheaper cards.

National Instrument is the cadalac of boards, and priced to match.

They give you 8 bit wide output or input ports, so an ASM IN or OUT command will drive these lines leading outside your machine.

It may seem very basic, but it does work. I've build some test fixtures professionally using these boards.

This sounds like fun stuff, I just don't think my eyesight is good enough to do it anymore.

Don't forget that LPT1 is an 8bit out and 4 bit in port (possible to input 8bits on some older machines)

Tommorow I'll try to resurect an old prog to make a stepper motor go left or right.

Thanks fellows,

now I got lots of stuff to study and try out. Well, students got time...:)
