sed 1330 / sed 1335 / s1d13700:

nota bene

dual-panel displays are supported since version 1.97.8, but untested!
s1d13700-based displays are unsupported before version 1.97.8.
all serdisplib versions before 1.97.8 had severe bugs in the initalisation code - because of these many panels with bigger resolutions did not work. hopefully all these bugs are fixed in 1.97.8 ...

description

sed 1330 / sed 1335 / s1d13700 are generic display controllers found in certain displays.

connecting an sed1330/sed1335/s1d13700 display to the parallel port:

intro

serdisplib supports five pre-defined wirings, user specific wiring is also possible through customisable wiring (in case five different wirings for one and the same problem are not enough ;-)

pre-defined wirings

valid for all pre-defined wirings: D0 to D7 are wired to pin 2 to 9

"WIRING=Original"

       CS .. pin 17 (nSELIN)
       A0 .. pin 16 (INIT)
       WR .. pin 14 (nAUTO)
       RD .. pin  1 (nSTRB)

"WIRING=PowerLCD"

       CS .. pin 14 (nAUTO)
       A0 .. pin 16 (INIT)
       WR .. pin  1 (nSTRB)
       RD .. pin 17 (nSELIN)

"WIRING=LCDProc"

       CS .. pin  1 (nSTRB)
       A0 .. pin 17 (nSELIN)
       WR .. pin 14 (nAUTO)
       RD .. pin 16 (INIT)

"WIRING=Tweakers"

       CS .. pin  1 (nSTRB)
       A0 .. pin 17 (nSELIN)
       WR .. pin 16 (INIT
       RD .. pin 14 (nAUTO)

"WIRING=YASEDW"

       CS .. pin 17 (nSELIN)
       A0 .. pin 14 (nAUTO)
       WR .. pin  1 (nSTRB)
       RD .. pin 16 (INIT)

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, "SED133X", "WIDTH=240;HEIGHT=128;WIRING=PowerLCD;INVERT=YES");
      serdisp_init(sdcd, "SED133X", "W=128;H=128;WIRING=DATA8,CS:nSELIN,A0:nAUTO,WR:nSTRB,RD:INIT");
      serdisp_init(sdcd, "S1D13700", "W=320;HEIGHT=240");

options

identifier	short	remark	default
WIDTH	W	width of display	240
HEIGHT	H	height of display	64
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
OSCILLATOR	OSC, FOSC	oscillator frequency (kHz)	9600
INTERFACE	MODE	interface mode (0 .. 8080, 1 .. 6800)	0
DUALPANEL	WS	dual panel mode (0 .. single panel, 1 .. dual panel) ¹⁾	0
WIRING	WIRE	pre-defined or customisable wiring	0

¹⁾ added in v.1.97.8

ranges, aliases

identifier	range	aliases
WIDTH	<=640; a multiple of 8
HEIGHT	<=256 (S1D13700: <=240); a multiple of 8
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
OSCILLATOR	[1000, 10000]
INTERFACE	0, 1	8080=0, 6800=1
DUALPANEL	0, 1

pre-defined wiring definitions

identifier	numeric id	protocol	description
Original	0	PAR	Original wiring
PowerLCD	1	PAR	PowerLCD wiring
LCDProc	2	PAR	LCDProc wiring
Tweakers	3	PAR	Tweakers wiring
YASEDW	4	PAR	YASEDW wiring

display signals

identifier	description	mandatory
D0 - D7	8 bit wide data bus	*
A0	data or command	*
CS	chip select input, active low	*
WR	write signal, active low	*
RD	read signal, active low	*
RESET	reset signal, active low; optional if wired to a hardware reset circuit
BACKLIGHT	backlight, optional

annotations

identifiers for pre-defined wirings are compliant to identifiers used in project graphlcd (a plugin for vdr)
