Identify Olimex SAM7-EX256 LCD Controllers

Could our friends at Olimex please identify the part number and manufacturer of the LCD controllers used in the SAM7-EX256 ARM evaluation board? The Olimex web site specifies that the board includes a Nokia6610 LCD with either a GE8 or a GE12 controller.

To fully understand the Olimex sample LCD driver shipped with the board, we need to refer to the LCD controller data sheet. To download the datasheet, we must know the manufacturer and part number of the LCD controller (GE8 or GE12).

Also, is there any way to tell which which controller is fitted other than the Olimex decal stuck to the face of the LCD?

Cheers,

Hi Jim,

I wish I could help you, but we buy these LCDs from Chinese trader company for surplus GSM parts.

They (the trader) have no glue what they sell, they only have good price :slight_smile:

So the real LCD manufacturer is unknown, every time we order we don’t know what we’ll receive before the parcel arrives, so far only two type of controllers GE8 and GE12.

The code we made is based on info found by googling for NOKIA 6610 lcd specs and try-fail approach.

Best regards

Thank you, Tsvetan.

From what I read, the two types of controllers that come with these Nokia 6610 displays are the Philips PCF8833 and the Epson S1D15600.

My guess is that the G12 model is the Philips PCF8833 while the G8 model is the Epson S1D15600. I have the G12 model.

Does anyone out there have the G8 model and would like to offer an opinion on this big mystery?

Cheers,

i can try to get one.

i let you know. I have 3 G12 here but my customer get the g8 one. i will try to make an exchange with it.

Hi Jim,

I’ve got a LPC2378 board w/ the GE8 LCD here - if you tell me how to determine the controller type I could test this.

Just wanted to make an additional note - We’ve seen a new Epson clone / replacement. Thats whats in the nokia displays we sell. Seems to be fine if you write exactly to the old Epson spec, but deviations that worked on the old epson can be… flaky.

I did some research and found this Swedish web site that sells the Nokia 6610 display currently used in the Olimex SAM7-EX256 board.

The photograph has the same GE12 decal that comes with the Olimex board. They say that the controller is a Leadis LD5176. Here is a link to this controller’s user guide.

They state that this controller is 100% compatible with the Philips PCF8833 controller.

This seems like it would be good information for the [wiki.](http://wiki.sparkfun.com/)
