adjustable contrast	yes
dimensions	module size: 27.2 x 21.5 mm; display area: 20.1 x 13.4 mm (datasheet)

some images


output generated by `testserdisp`	some test output rendered by `multidisplay`

test output generated by `multidisplay` on a solaris 10 box
remark display content looks much better in reality. it is not easy to photograph an OLED because of its high contrast. thus the images shown here are far away from the real impression.

configuration notes

configuration notes for `graphlcd`

the default colour in graphlcd is set to black. current versions of graphlcd only draw information (when background and foreground colour are set to default) when using the foreground colour.
when using OLEDs (and depth > 1) the problem now is that information is only visible if the drawing colour is NOT black (because the background of the whole display is black). because of this the foreground colour has to be set to something else (usually white (0xFFFFFF)).

example configuration in graphlcd

 [serdisp]
 Driver=serdisp
 Device=/dev/parport0
 Controller=OLED96X64X16
 FGColour=0xFFFFFF

wiring

circuit:

connecting a Pictiva 96x64x16 OLED display to the parallel port

part list:


    Part#   Type                Value                  Annotation
    ---------------------------------------------------------------------------------------
    R1-R12  Resistor            1 kOhm       
    R13     Resistor            10 kOhm
    R14     Resistor            920 kOhm               or 1 MOhm
    C1-C2   Capacitor           4.7 uF
    C3      Capacitor           10 uF

annotations:

according to the datasheet, VCC (OLED power supply) is 11V, but 12V seems to be fine, too
VDD (logic power) needs to be 2.4V - 3.5V. thus 3.3V is fine because it can be gained directly from the ATX power supply
pin 4 (VSS) can be left unconnected if pin 25 (VSS) is connected to GND
the circuit is hard-wired to parallel bus data-transer
interface mode: 8080 (BS1 and BS2 wired to VDD)
hardware reset is used
LCD/D0 (pin 12) must be connected to PARPORT/D0 (pin 2), LCD/D1 (pin 11) must be connected to PARPORT/D1 (pin 3), and so on

passing options through serdisp_init():

intro

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, "OLED96X64X16", "CONTRAST=5;INVERT=YES");
      serdisp_init(sdcd, "OLED96X64X16", "DEPTH=8;INTERFACE=6800");

options

identifier	short	remark	default
ROTATE	ROT	rotate display (1 == 180 degrees)	0
INVERT	INV	invert display	0
DELAY		delay after each write/read operation. 0 .. no delay 1 .. one call of gettimeofday() >1 .. delay at least x nanoseconds	0
CONTRAST		set display contrast	5
DEPTH	COLS, COLOURS	colour depth	16
INTERFACE	MODE	interface mode (0 .. 8080, 1 .. 6800, 2 .. SPI)	0
WIRING	WIRE	pre-defined or customisable wiring	0

ranges, aliases

identifier	range	aliases
ROTATE	0, 1, 90, 180, 270	YES=180, NO=0, TRUE=180, FALSE=0
INVERT	0, 1	YES=1, NO=0, TRUE=1, FALSE=0
DELAY	>= 0	NONE=0
CONTRAST	[0, 10]
DEPTH	8, 16	65536=16,64k=16,256=8
INTERFACE	0, 1, 2	8080=0,6800=1,SPI=2,SERIAL=2
