Ethernet LCD - Just an IDEA... or a dream

Post by limbo »

Hey hardware maniacs take a look here:
http://www-ccs.cs.umass.edu/~shri/iPic.html
http://www-ccs.cs.umass.edu/~shri/iPicTech.html

The project is an tiny web server! a really tiny web server =D>

This project gave me an idea about an TCP/IP interface for LCD :shock:
I don't know if its possible cause the above project is the opposite (it serves the TCP/IP network) but I introduce my idea here for discussion!

What do you think? :roll:

This webserver requires a SLIP. It cannot be plugged directly into an ethernet connection. It needs something to translate ethernet to serial.

The easiest thing I found so far would be the XPORT. It can replace a serial connection in minutes. It comes with a com port redirector that makes a virtual com port on your computer. So you dont need to do any plugin programming for it to work and most serial LCDs can be converted to be used with it. The drawback is its $50 US dollars.

I have once built an ethernet ledmatrix display http://www.harbaum.org/till/ledmatrix. Converting this to an ethernet based text display is quite simple as the ledmatrix drivers are more complex than those simple 8-bit text lcds. There are several other microcontroller based ethernet projects and most of them feature a simple text lcd interface. So warm up your soldering iron and just do it. Everything you need is available in the internet.

Hey Tillo, The dot matrix project is impressive! :shock:


Since you're very experienced in Atmels and μCs, Can you give a try and create a project in our (LCD users) needs?

These little ethernet to serial converters are a direct drop in for serial LCD's that have TTL input. You may need a 3.3v TTL to 5v TTL conversion chip though. I messed around with one of these about a year ago. Simple to use but kinda pricey for a LCD hobbyist (Xports version is $50 USD).

As for internet LCD display - I have one question is it possible to connect LCD display with parallel interface to printserver with same port ?
I have Linksys printserver with 2 LPT ports and I wonder if I can use one for LCD ?

I just finished a DIY ethernet LCD backpack. Thought you might be interested, I was inspired by this thread. I posted about it here:

I've had this for about a month now. Everything is simple to use and looks very sharp coapmred to the other 32 LCDs I looked at best buy and Circuit City. Make sure you by a component cable and have HD cable to get high res imaging or everything will look blurry.
