hi...
now i learn how connect the parallel port with external circuits and how control in electronic circuits by delphi programming.
can any one help me about how i can use delphi programming to program and control with parallel port?
thanx for all

 

Will Delphi let you set and read individual output lines in the printer port? If so, it should be no problem.

 

It's an OO descendant of Turbo Pascal

I have no idea if it can do bit fidling, but I bet it doesn't run under modern versions of Windows. Looks like you need a DOS machine or maybe up to Windows 95. After that I think all bets are off.

 

It does run under 2K, XP or Vista. It can do pretty much anything. However, to access parallel port under Windows properly you need to go through the Win32 APIs.

The easiest way is to find a VCL component for parallel port, then you just need to drag and drop it.

thank u
in fact i can use pascal programming for it, but really i want learn how i can use delphi(visual ) .

yeah
i want it please if u want.

 

I've never messed with it. Look for instructions with the same function as PEEK and POKE in BASIC. They let you set and read bits at I/O locations, like the printer port.
