nota bene

colour-mode displays require a rather high throughput which isn't provided by parallel ports. because of this the update speed is not very fast!

connecting a nokia 3510i / 3530 display to the parallel port:

intro

the wiring is based on the wiring of optrex 323 and pcd8544-based displays to the parallel port. as i didn't know of any other projects like this (with nokia 3510i/3530 displays connected to the parallel port) i had to chose a wiring-'standard' for myself.

    ---------------------------------------------------------------------------------------
    R1-R5   Resistor            1 kOhm
    R6      Var.Resistor        eg. 100 Ohm            or higher value if needed;
                                                       or simply a resistor with fixed value
    C1      Capacitor           eg. 0.1 uF             for stabilisation of display
                                                       (0.22 uF or other values are fine just as well)
    T1      Transistor          eg. BC547    
    D1      Diode               eg. 1N4148   


    

remarks:

R5, R6, T1, D1 are needed in combination with LED background light only!
be warned: without background light the display is hardly readable!
Vio ought to be connected to 1.8V but I did quite well without even connecting it.
as always: just because it worked for me doesn't mean that it will work for you!
i used the original SMD-leds from the Nokia 3510i cellphone. they needed some value around 3.1V.
as i didn't like to generate two voltages, i also connected Vflash to 3.1V (rather than connecting it to the recommended 2.8V)

and one again: just because it worked for me doesn't mean that it will work for you!
if your display dies in flames don't blame me.

hardware reset vs. software reset:

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

part-list is the same as above with the following exceptions:

    Part#   Type                Value                  Annotation
    ---------------------------------------------------------------------------------------
    R4      Resistor            10 kOhm
    C2      Capacitor           10 uF

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, "N3510I", "DEPTH=8;CONTRAST=5");
      serdisp_init(sdcd, "N3510I", "COLOURS=4k;BACKLIGHT=YES");
