s1d15g10-series

NOTA BENE:

two different types of displays (with different controllers) are used in these cellphones: Epson S1D15G10 (usually with a green connector) and Philips or compliant (PCF8833 or LDS176) (usually with a brown connector).

a detailed description of how to distinguish between the different displays can be found at Mike's Electric Stuff / Nokia colour LCD driver identifier.

the following nokia-cellphones are known to have one of above-named displays: Nokia 2600, 3100, 3200, 6100, 6610, 7210, 7250 (and maybe some more).

this page is about S1D15G10-based displays!

pin numbering used by nokia and some lcd projects - brown and green connectors (picture taken from thomaspfeifer.net)	pin numbering used by Abhishek - because it was printed like this on the connector of his display! (picture by Abhishek Dutta)

important:

as shown in the pictures above, different pin numberings can be found (because green displays with a reverse numbering printed on the connector are available). Abhishek burned two displays because of this fact!

only the numbering is different, the signals and voltages are always the same (VDD is always bottom/left, /CS is always top/left).

this page will use the left pin numbering (VDD = pin 1)

annotations:

• pin 1 and 6 can either be both connected to the same power source or pin 1 can be left open (according to Abhishek)

hardware reset vs. software reset:

to save one wire it is possible to replace the /RES-wire through a R/C-circuit.

pro

one wire less

contra

display can no longer be reset by software

using the third parameter of serdisp_init(), driver specific options and custom wiring can be set.
common information about passing options and customisable wiring can be found in a separate document.

    examples:
    
      serdisp_init(sdcd, "N6100", "DEPTH=8;CONTRAST=5");
      serdisp_init(sdcd, "S1D15G10", "INVERT=YES;BACKLIGHT=YES");
    

if the display output is shifted in x or y-direction, try using OFFSETX and OFFSETY (options added in version 1.97.7)

default offset settings: OFFSETX=1, OFFSETY=1 (Abhiskek uses OFFSETX=0, OFFSETY=2).

  0 .. no delay
  1 .. one call of gettimeofday()
 >1 .. delay at least x nanoseconds
