    I bought a cheap, old ‘scope and found that the O-Clock output was mirrored. I had no luck finding a suitable hardware solution so I tackled changing the firmware to invert the X-channel voltage. It turned out to be just a couple of lines. Details and photos in this flickr set

    OK, may be a silly question, but the board seems to have white paint around the pin contacts where I’d expect to see copper. Do I just ignore it and solder as normal? It vapourises??

    yes you can set the contrast, see p14 of the datasheet, the “Set Vop” cmd seems to control contrast

    1) don’t give up
    2) read every posting
    3) follow every link
    4) try every suggestion
    I have mine working now! The secret was oz-solutions’s linked-to observation about the second code example which does more initialisation. I suspect that the default contrast etc makes the screen blank.

    Well I tried cluening’s voltage divider and still nothing so I suspect, like Skye, I have a dud. The board is a little warped
    :-(

    I’ve followed the linked-to Arduino example and I get nothing on the display. Should it just work without any other components? The link mentions a possible cap on VOUT but there’s no such pin. Googling has suggested my Duemilanove’s digital pins will be @5V but I need 3.3V?
    I have connected LCD:Arduino as
    VCC:3V3
    GND:GND
    SCE:7
    RST:6
    D/C:5
    DN(MOSI):4 is this “SDIN”??
    SCLK:3
    any help would be appreciated, thanks!
