 Bigger Bigger  Smaller Smaller  Reset Reset

Anyone know if this one:

http://cgi.ebay.com/Serial-LCD-Kit-117-9600-Blue-LCD-Assembled_W0QQitemZ360163475771QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item53db6a813b

Will work similar to the 16x2 Serial displays they sell on sparkfun?

Indeed, all though, you could make your own if you wanted to.. depending on your materials. It would be fairly easy, and you could add your own customizations smiley

Hm, I'm just curious. The Graphical serial displays, how much more complex is it to get them working?

For that LCD driver you may want to read this:
http://www.wulfden.org/TheShoppe/k107/about.shtml
seems he has a library and example code for use on an arduino.

Why would you want that one though because the serial 20x4 lcd from sparkfun is about $10 cheaper, true it is not blue but buying their serial module and a 20x4 lcd would still be cheaper.

Quite a bit, relatively easy to show standard text, and simple shapes are not too difficult. It just takes a lot more code to do the complicated things.

For $15, the same screen is here:

And is supported by native Arduino code.

Not quite the same LCD... the lcd he's asking about is controlled via Serial, rather than like 6 pins, just uses 1. It works with commands like Serial.print("HELLO WORLD!")   etc. Just saves code space and quite a few pins! And some have extra abilities such as a contrast control, backlight, all via 1 pin. (not including ground and power!:D)
