---> How to control Graphic LCD's ? <---

[TiagoSilva]

Hello everybody, i had some problems accessing the forum and i don't know why, but here i am.

I need some informations concerning Graphic LCD's, do they have some standard like the Character ones ???

Well i recently acquired one (a friend gave it to me), but how you imagine it can be frustating when we have such a nice device and don't know how to start .
Here is were you enter :lol: , if you know how to use this fantastic devices help the other starting by me

It's not color but it's nice anyway, tell me how can i use it, and their comunication protocols and the datasheet if you can too.

Well, thank you for your time.

Graphic LCD's aren't as standard as text ones, a friend of mine has interfaced one to a PIC16F877, you can see his project here

Hello Mr. Nigel and All, i've seen the page and has i had eard the CONTRAST needs NEGATIVE voltage but my LCD has DC-DC converter, that means that it can support positive/negative right ??
And it is better to have it's datasheet before trying to use they are very delicated and i don't whant to mess it up, i allready went to the manufactors page but those silly hill billys only have the sales and sales contacts on the damn page and no development zone (how they expect the others start using their LCD's ?? Perhaps with witchcraft we can guess the pin outs and protocols :lol: :lol: ).
Anyway help me find the datasheet please that is the more important i can try to guess the protocols :lol: but the pin outs is crucial i don't want to burn it :lol: .
Thank you all for the time spent, goodbye.

I am sorry but my russian isn't very good!!!!! Here is the **broken link removed**,so I let you translate that :lol: .But you can tell what is what, check attached files as well. Go to http://babelfish.altavista.com/ and chose Russian to English then in the "Translate a Web page" put **broken link removed**

Have fun this weekend!!!! 8)
