I just finished a write up showing how I made my Kent Display (ChLCD) work to display a full screen image. If anyone is interested, I've posted the tricks and some sample code on http://www.rustynailworkshop.com/Projects/Entries/2010/8/9_Arduino_Powered_Kent_Display.html.
I plan to use this in a display project I have, and I know several people have had trouble making this work. I'm sure someone can improve on what I've done.
Looks good! What's the difference between this Kent display and a regular dot matrix display?
Cool.
Those chLCD units look very nice indeed. Good work.
Luidr, the main differences are that they retain their display even when the power is cut and [apparently] are more readable in bright sunlight than the usual screens. Like eInk displays.
The refresh rates are on the order of 2 seconds. On the positive side, you write to them once, then cut the power and the image stays. They sell them at SparkFun.
I see, thanks, may be a good thing if you plan on battery operated projects.
