output generated by `graphlcd`	output generated by a skinable beta version of `graphlcd`
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.

    C4      Capacitor           10 uF

annotations:

according to the datasheet, VCC (OLED power supply) should be around 12.5V, 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
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 20) must be connected to PARPORT/D0 (pin 2), LCD/D1 (pin 21) 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, "OLED96X36X1", "CONTRAST=5;INVERT=YES");
      serdisp_init(sdcd, "OLED96X36X1", "ROTATE=YES;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
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]
INTERFACE	0, 1, 2	8080=0,6800=1,SPI=2,SERIAL=2

pre-defined wiring definitions
