That is not how this forum works. You tell us what you plan to do and someone will tell you if it works.
see my website: www.geocities.com/russlk
Can you do it in Visual Basic? If so I can help, VB is a free download now
VB2005 rocks. I used it for a while, but decided to learn c because everyone else uses it.
There is no "I" in "team", unless Apple makes it... Then it would be iTeam.
Cool. I noticed that visual C++ is a free download too.... What's the catch?Originally Posted by gramo
Inside every little problem, is a big problem trying to get out.
They are express versions
You have to use .net to make decent programs.Cool. I noticed that visual C++ is a free download too.... What's the catch?
.net is a pain the the azz.

use a few serial to parallel shift registers connected to the parallel port...

The parallel ports data lines and strobe line can easily be used to clock 8 bits of data into a register array like Marks suggested. You'd simply set up some kind of timer in your C program to send out the next column of LED states one by one at any rate. The shift register wil move one column down the line at a time until they start to 'fall off' of the end. If you want a non-moving display don't use a timer just clock the LED data out as fast as possible. Human eyesight can't keep up with a computer so you're going to only notice a tiny blur before the entire display is updated.
"Because I be what I be. I would tell you what you want to know if I
could, mum, but I be a cat, and no cat anywhere ever gave anyone a
straight answer, har har."
Is some kind of interfacing? If so I have done a project before of using led matrix a 5x8. I used 1 IC and I can form any patterns on the LED, if your interested with it just tell. I forgot the IC and Ill have to check my compilation first. I used the parallel port as the driver for the 5 columns and the IC to the 8 rows. I am only using the data pins of the parallel port, I am using VB.
its well!
Respected sir
