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



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.Neo wrote: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.
as i know,epp is a one of parallel port mode.others are spp,ecp.Neo wrote:What is EPP when compared to microcontrollersPIC16F877A 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.
ok Neo,i understood lpt programming is defficult than microchip programming for my knight rider.Neo wrote:Hi Nandika,
Please ask different questions in new topics. Otherwise it is confusing for readers.
