i want to know about parallel port programming.
i want to create 70 LED drive as knight rider.
if program by in vb.net,good
plz help me....

i know something about parallel port programming in vb6 using WIN95IO.DLL file.
but i have not sound knowledge.
if you have resource for get knowledge,plz give me or EC.
my mail address is <link removed>.
thank

Operating LEDs through LPT was popular a decade back. But now even 15 year olds use microcontrollers to do that. Unlike the LPT which has only 8 output pins, a basic microcontroller such as 16F877A (the most popular one in Sri Lanka for learning) has many output pins. See
New Knight rider Flasher. Both RAT and Rksk experimented on this.

yes lpt programming is old.but,as i know,lpt port has several mode.EPP(enhanced parallel port) mode has output grater than 8.SPP(staranded parallel port) has only 8 output.

What is EPP when compared to microcontrollers
PIC16F877A has 33 GPIO pins. Have a look at my
How to start with Microcontrollers. With some knowledge in C (or Assembly), I'm sure you'll be able to do lot of innovations with them. Take my word, it is very easy to start. Only thing is you need to collect the required components at the beginning including a microcontroller programmer.

as i know,epp is a one of parallel port mode.others are spp,ecp.
it is not about microcontroller.
i have tried to prngram pic16f84a chip from DJM programmer.but,i could not do it.
i learned about chip programming from "Vdusara" articles.
i know something about this.but,i have not money 4 spend to buy a chip.
i can creat a programmer.but,i have not knowledge about it connect with pc.
plz give solution...?

Hi Nandika,
Please ask different questions in new topics. Otherwise it is confusing for readers.

ok Neo,i understood lpt programming is defficult than microchip programming for my knight rider.
thank Neo and all other friends for teach it.
now,i am interesting about PIC programming.
thanx all
