Hi, i just want to know the exact controller on siemens C65 lcd, after a few captures of the bus i figure out that it responds to samsung controllers i'm currently using S6B33A2 commands but i can't figure out the correct one.

this is how the lcd looks

Hi netbit!

Did you figured out the controller type used on C65, or at least the initialization, or/and any other sequence?

You were actually able to get it work, to display something?

I would highly appreciate any help!

Thanx, Szabi.

hi,
i haven't figure out the exact one but the commands of the samsung S6B33A2 controller seems to work fine

I understand, thx.
Unfortunately there are 2 types of displays used on C65 phones, with different controllers.
The samsung commands doesn't work for me.

netbit, can you please tell me which one is the correct pinout:

LED, LED, 1.8V, GND, 2.9V, DATA, CLK, CS, RESET, RS or
LED, LED, 1.8V, GND, 2.9V, DATA, CLK, RS, RESET, CS

Thank you!

hi,
this is my first C file for 8051 mcu to control the lcd, it has the pinout and commands that i use

Finaly I managed to buy a new display.
The actual controller is S6B33B2.
(For the other type, I still was not able to find out the controller used.)

I also made a driver for LCDHype: http://lcdhype.condense.de/index.php?showtopic=4834

There's some useful info on the various S65 displays here. Looks like there are three different variants, Sharp, Hitachi and Epson.

When I tried ordering one of these LCDs the shop asked the serial number of the cell phone, so I guess they must be able to cross reference somehow.
