I found this LCD make for cellular phone Nokia 3310 by browsing the web at www.jelu.se. There is many interesting things about this LCD: low price, easy to interface via SPI port, can support graphic and text and consume low current. The only thing that I did is writing code who gives you friendly functions to support this LCD. The last version of the library only send the bytes who had changed since the last update. It's considerably reduce the refresh time who can be very important in a batteries powered system.
This LCD is very different from the other standards text 2 x 20. This graphic and text LCD is 320 x 200 pixels. This LCD have differents memories map for the text and graphic region. If you buy this LCD in a "real" electronic store you will pay like 400$ each but you can find it brand new in a surplus store for 50$!!!. I used this LCD in a major project to display charts and a lots of information collected around my house: temperature, humidity, wind speed, etc. This LCD is perfect for project that needs to display a lot of information.
The OneWire protocol which in fact needs two wires (data and ground) is fantastic for many reasons: you can have a very long cable (250 feets), you can have multiples of devices on this cable and with a simple code you can poll those devices to get temperature, voltage, switch position, wind speed, etc.
All my source codes were taken from my personal projects.

with ICCAVR. You can find the header and source CRT files by downloading their compiler.
All is for your information and everything is AS IS without any warranty of any kind. No other files are available and I don't make any modification for any body.
