interfacing AVR with EPSON EG7502 LCD

[zetd]

Hi,

i have EPSON EG7502 (L1F90003P .. new name) ,in new condition, its 320x200 px LCD, mono, but there is "no one"(couse i had googling on it) knowing about its pinout name.

There is any body know it?

Hi,

They sometimes use custom PN's, can be quite confusing. More important, what kind of controllerchip is on the panel, like a SED1335 etc. this is actually the most important thing to know.

from a source
  EG7502 = SED1360(LCD Controller) + SCI7500(Power Supply) + SED1580 / SED1751 (XY-driver)

  from the module, i just can see SCI7500

  EG7502 (L1F90003P) have 22 pin, there is on net datasheet for EG7500, and EG7504, but, its seem quite difference, and i am too afraid, to do some experiment to hack its lcd (.. mean guessing it pinout, regarding EG7500 & EG7504)

your The MAN...

..btw.. how could you get it, did u have its datasheet?

i have code to interface with 320x200 LCD, may works on my EPSON EG7502 LCD.
