Hi guys!
I have an assignment where i need to control (turn ON/OFF certain LEDs and turn ON/OFF all LEDs) with the usage of LPT port and two 74HC595 Shift Registers. How can i use an Arduino Uno with this project and how to assemble all the elements?
Thanks!
This is a scheme i found, but how am i supposed to connect my LPT port to the Arduino and then read and output the information that i send to the LPT port so a certain LED to light up?
By LPT do you mean the old PC printer port? There is still hardware that has it? First do you have an original version, which had limitations in the interface? Or the later versions (EPP,ECP) which were a more general parallel interface? How do you access it? How much control do you have over I/O lines (OS and driver dependent)?
It seems to be a rather bizarre assignment. If I were doing it I would use a couple of octal latches and eliminate the Arduino.
Yes, i mean the old PC Printer Port. I had to buy an old enough PC so i can make my university assignment. It's the old, pink one, im also not familiar. If you could help me make it without arduino, it'll be very good..
If you have an old computer with an lpt port then you would use a C or python program that runs on that pc to access the lpt hardware through the operating system and turn leds on and off.
Odd assignment for sure.
What OS are you using on the PC? It has been decades since I used the printer port directly. I remember Linux had some direct support for controlling the I/O. I have no idea what kind of support Windows has.
