LPT access on pins In/Out for real-time measurements on a PCI card
Posted on 2007-03-23
I bought a new computer with windows XP-SP2 on it where is everything on it USB's,firewire, and ethernet connections ... but the standard port LPT was absent, i didn't pay attention on it, i bought a PCI card to put in a slot with onte LPT and 2 COM's, now i have the same problem as others to access on pins in/out as i could before until i used windows 98 and the Borland compiler wit hthe instructions inportb/outportb .The problem with PCI cards is that there is an indirect address to LPT's and specila initialisation as i understoud
Somebody knows how to initialize such type of card? and how to access at the pins .. i need to make some measures real-time on them ... and what was possible before easily, becomes very hard to do now
Somebody had the ame problem and could solve it?
I use CBuilder6 ( i have the precedent versions in case impossible with that one and the normal C++ compilre 4.5 or 5 form borland wher the instructions in/out and inportb/outportb where present )
I saw by case one time on net .. but sad i don't remember where that linking some file from the old compiler, a file *.obj gives the access on the instruction that where deleted on the CBuiler versions, true or not?
Sorry for my english if many mistakes .... if somebody can help would be happy ... that could be just knowing if somebody sales a driver that gives that access on a LPT trough a PCI card .. any solution welcome, not necessarely writing directly code for it
