visual basic program for parallel port interface - Electronic Circuits Projects Diagrams Free

group_x3m · 22nd May 2006, 10:49 PM

I need ur help guys. I have an electronic project that needs an output from the parallel port. I already have a software for controlling the parallel port output but what i need is an exact source code using visual basic. i am just a beginner in visual basic. can anybody give me the exact source code or program that i could use to control the output of the parallel port? i just need a basic source code where i could start with. i hope you could help me in this one.. thanx!!

If you check my PIC programmer software, there's a driver you download which allows port access under 32 bit Windows (NT etc.). The driver includes example software for Visual BASIC and C.

u could get the source if u browse codeproject/codeguru sites

thnx for ur help guys!!! i really appreciate it! just in case u have other sites that u could suggest or maybe u have the exact VB code that u could paste here, it would help me a lot. i just need a simple code that would send a binary 1 and 0 signal to the parallel port. thank you so much!!

Simplest code would be to OUTPUT a byte of data to port address 0x378
The data appears on the parallel port pins 2 though 9, these correspond to D0 - D7.

You may need additional libraries to be able to do this under WinXP/2K/NT
see.. http://www.aaroncake.net/electronics/vblpt.htm

Note that the parallel port can only source about 6mA of current so you should buffer the signals.. but you might be able to drive a transistor directly for simple applications.
