I'm going to develop a thermostat with Arduino and I'd like to use the display coming from my old Nokia 6230i to show any needed info. It's a color display 130x130 part number 4850339 (here a link just to show you the subject: http://www.ebay.co.uk/itm/Nokia-6230-LCD-Part-Number-4850339-/251164456942).
Now my problem is that I really cannot find any pinout, connection diagram or any info about the interface: I just know it has more than 20 pins. Is there any place where I could find a datasheet or at least understand if it uses a known interface to connect: google is not helping...
Thanks in advance for any info.
