    SSD1325 Displays
    -----------------------------------------------------------------------
    The driver is used in multiple displays (128x64, 128x32, etc.).
    Select the appropriate display below to create an appropriately
    sized framebuffer, etc.

    SSD1325_128_64  128x64 pixel display

    SSD1325_128_32  128x32 pixel display

    You also need to set the LCDWIDTH and LCDHEIGHT defines to an
    appropriate size
