 26 Jun 2008 12:05 parallel port interfacing with Turbo C++ |
|
|
|
Hi
I want to use the parallel port of my computer to make external electronics work. I am using Turbo C++ in Windows XP. I heard that you have to include inpout32 to make the programme work. Is just placing inpout32.dll in the sytems directory sufficient? If not, how do I call inpout32 from Turbo C++?

inpout32.dll is a dll, to use the methods exposed from this dll you've to load it and then call the desired functions.
Take also a look at this link:

Yes vkixer, placing inpout32.dll in the systems directory should be fine (if you did)
You said that your machine runs on winXP, you can also download and install portTalk or UserPort in the software downloads section in this board so can have access to your parallel and serial ports

No you don't need any file . i did without the file inpout32.dll.
you just use the functions :inp, outp . knowing the port number .
Here is the code :
#include<stdio.h>
#include<conio.h>
int main(void) {
unsigned port = 0x378 // first pin in parallel port 0x378-0x37f
int value ;
value = outp(port,'c') // c is the number you'll send to LPT
printf("value %c sent to port %d\n", value, port);
return 0 }
send me if you need anything .

@mezo
Thank for reply, I can't test it now simply bcz I've to install the TC++ environment, I've used TC++ some year ago (at my college with DOS based release, I can remember usage of some library extension to code program with windows), now I'm using VC++, but what I need to know is just to be sure about pratical use of the in and out in WinXP environment.
Thank again.
Bye
