Parallel port programming

[Joakim Christiansen]

First credit to the people leading me to this (I did not get their code working btw):
http://www.purebasic.fr/english/viewtop ... 12&t=36570 (Windows & Linux)
http://www.purebasic.fr/english/viewtopic.php?t=29852 (Windows only, port of DLL)

The reason I had problem getting it to work was because I needed the updated DLL file for x64 systems, this will install the needed (signed) driver (x32 or x64) automatically. It and the source code can be downloaded from here:
http://www.highrez.co.uk/Downloads/InpOut32/
For x32 and x64 systems one can use the x32 version of the DLL but for an x64 only application one must use the x64 version of the DLL.

Now I release some code updated for 5.20 LTS and using prototypes. Only for Windows though, if you need Linux support see the linked thread and make it work yourself.

Code: Select all

EnableExplicit

Prototype p_Out32(portAddress.w,value.w)
Prototype p_Inp32(portAddress.w)

Define i.u

If OpenLibrary(0,"inpout32.dll")
  Global pPortOut.p_Out32 = GetFunction(0,"Out32")
  Global pPortIn .p_Inp32 = GetFunction(0,"Inp32")
  For i=0 To 255
    pPortOut($378,i)
    Delay(100)
  Next
  CloseLibrary(0)
Else
  Debug 1
EndIf

I tested this with LED's (and resistors to limit the current) connected to my parallel port header (on the motherboard, yes a few have them) and got a nice flashy binary counter. Using Enhanced Parallel Port one can even use all those 8 pins as inputs too (check your BIOS), more information here:

Is it awesome?
Yes! Giving your computer IO ports that you can use as you like sure is handy!
I for example will try making it interface directly with an old floppy disk drive and make backups of some diskettes not readable by Windows.

On, PureBasic written kernel driver and dll for it, similar to InpOut32. http://www.purebasic.fr/english/viewtop ... 05#p405305
Module for work with ports. http://www.purebasic.fr/english/viewtop ... 50#p418350

Both very interesting, I still love parallel (and serial) ports.

Thanks

That is quite sweet, I'll try your driver too!
It is a little nicer when everything is coded in PB, thanks!

Interesting, thanks!
