Hi everybody

I have got a graphical LCD (LM213, hitachi) and I want to control it with a microcontroller, but I can't find any schematic and programs. It is posible to connect some switch, which I can controll to, too. (To make a menu) (four switch, an enter, a clear, up and down switch) I have got AT89c52 microcontroller.

Thanks

You are probably still going to need a controller for your LCD too.

Hi one~Zero

I have got the control panel for the LCD (this is a HD61830 IC with m 5839B IC (Dot matrix LCD 40 dot segment driver) there is lot of on this panel) I try it it works with computer fine, but I want to controll without a computer. I think a microcontroller is good (at89c52, 8bit with 8K byte flash) I want to make a menu for this LCD with four switch (somethink like that a mobile phone) if it possible

thanks
