  • I made an Arduino Library for this. It does SPI in Software so it wouldn’t interfere with the Ethernet Shield (for example).

  • The sample Code for the display doesn’t work on an Arduino Duemilanove out of the box. You have to adjust SPI clock speed and data clock to get it to work.
    Replace this line:
    SPCR = (1 << SPE) | (1 << MSTR) | (1 << SPR0) | (1 << CPHA);
    with this:
    SPCR = (1 << SPE) | (1 << MSTR) | (1 << SPR0) | (1 << SPR1);

  • Does the board need 5 or 3.3v on VPWR? The DataSheet says it needs 4-9 V supply and 3.3V logic power.

No public wish lists :(
