LC79401 Display

Hello!

So I got my hands on one of these LCD's
It is POWERTIP PG320240WRF-CNN LCD, judging by the model number I guess it's 320x240 LCD.

By googling I got this datasheet:
http://www.scancraftdisplay.se/File/Powertip/PG320240WRF-CNNHS1.pdf

But I haven't found much about has this thing ever been connected to arduino.
Pictures are attached, it seems that it has LC79401 driver on it, I know that there are drivers for HD44780 driver, and graphic LCD drivers written for arduino, but, is there anything compatible with this thing? :slight_smile:

I would like to put it in some good use but I haven't got much expirience with driving LCD's so if there is anyone who can help please do reply :slight_smile:

Thanks! :slight_smile:

Hi

This is a controllerless GLCD. The mentioned IC belongs to the columns/segment pair of drivers.
It is considered to be almost impossible to drive this kind of displays with Uno or Mega boards.
To my knowledge, libraries also do not exist.
