A PC is such a dull device. With my other computers it is so much fun to control other devices, especially the 6502 SBC’s are great for that.
What would be great is to let the PC talk to a SBC, with something faster than a serial port. Or have the PC control the SBC via that serial port with a program much more intelligent that hyperterminal.
So I have been looking lately at ways to get something done with that.
Pascal as programming language, Delphi 7 is what I have.Â Good books, lots of information on the internet very stable and a functional very rich version. FreePascal and Lazarus are fine too, I have made console programs with FreePascal. But I am a bit tooÂ unexperienced with windows programs to fight with Lazarus, still a beta.
First program is TEST LPT. Gives access to all pins of the parallel interface,Â good for testing. I learned a lot, I/O port access, all the visible things, event driven programming, object orientation, make a help file, add a menu, add an installer. All theÂ essential things to create a professionalÂ program. I know how to program for someÂ decades now, I have now learned to do that in Delphi’s rich visual environment.
Here is the page I have devoted to parallel port access.
