i have this LCD which i am currently not using, but planning to use again.
does anyone have an idea how i can interface this lcd with a arduino mega2560?
Interfacing with a new display can be challenging even when you have full documentation for the device. I did not see any references on the manufacturer's site regarding datasheets, protocol details, or any other specifics. They do not appear to provide source code for their driver either.
Check around to see if anyone has released an open driver for the display. While it is entirely possible to reverse engineer the display/interface/protocols, you need to ask yourself if it will be worth the time and expense. There are lots of other displays available which have freely available documentation, code examples, etc.
Admittedly I did not do a thorough search for this information; you will need to do some digging. It is quite possible that the information is available from the vendor, or that the display is already supported by another project (GLCD, etc). Locating a datasheet for the display would be a good place to start.
Full graphic Display for connection to USB 1.1 or USB 2.0.
It only has a usb connection and is intended to be used with a computer with usb port. It has no connection for an arduino mega 2560, unless you use a usb host shield or arduino mega adk.
in that case i'm going to lookup the datasheet for this display....
