3 GND GND (ground)
4 SI serial data input of LCD
5 SCLK serial clock line of LCD
6 Vio 1.8V chip power (not connected)
7 Vflash 2.8V display power
8 Vout output of display-internal dc/dc converter
(Vout -> capacitor -> GND to avoid noise)

part list:
Part# Type Value Annotation
---------------------------------------------------------------------------------------
R1-R4 Resistor 1 kOhm
C1 Capacitor eg. 0.1 uF for stabilisation of display
(0.22 uF or other values are fine just as well)
hardware reset vs. software reset:
to save one wire it is possible to replace the /RES-wire through a R/C-circuit.

modified part-list:
Part# Type Value Annotation
---------------------------------------------------------------------------------------
R1-R3 Resistor 1 kOhm
R4 Resistor 10 kOhm
C1 Capacitor eg. 0.1 uF for stabilisation of display
(0.22 uF or other values are fine just as well)
C2 Capacitor 10 uF
- pro
- one wire less
- contra
- display can no longer be reset by software

common information about passing options and customisable wiring can be found in a separate document.
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, "PCF8511", "WIRING=0;INVERT=YES");
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 | |
| BACKLIGHT | BG | switch background light on or off | 0 |
| WIRING | WIRE | pre-defined or customisable wiring | 1 |
