If anyone is intrested about that kind of adjusting methode. check Those digital potentiometer's from dallas.
here's a link http://para.maxim-ic.com/compare.asp?Fam=Dig_Pot&Tree=DigiPots&HP=DigitalPotentiometers.cfm&ln=

If planning to use that, then remember this! Usually you cannot connet more then +-8V and few milliamp's. Other wise that digitall pot will burn!!!
So if more is to use connet that to adjustable voltage regulator.

There are severall modells. I have DS1869-10. Contrast adjustment trough to momentary push button or even one if prefered 8)
In my case that has to be connected to adjustable voltage reg. My LCD reguirs negative voltage that is -8V to -12V

I higly recomend to read those datasheet's before connecting any voltages.

Nice idea. :D

And then some ideas that i'd like to make some day (i started work on usb/serial lcd months ago but haven't had time for it lately):
-some buttons connected to the microcontroller
-control computer/lcdinfo with the buttons
-backlight adjustment based on some events in lcdinfo / time of day / etc.

really nice plans! :D

usb lcd would be soo nice!!! 8)
I wish you all the best luck with project!
btw I have also thinked an lcd back light mod, that would use RGB led's! What I have read those can display all visible colors.
Only draw back with those is the fact that they are reeeaally expensive! :cry:
Well even three color's would be nice and that would be less expensive.

To mention that if you don't know yet and for others:

You can find more information about usb2lcd on schijf's liquid-mp3 page:

Liquid-MP3

There is also information about controllers and so on.
