NAME

    Device::Chip::SSD1306 - chip driver for a SSD1306 OLED module

DESCRIPTION

    This abstract Device::Chip subclass provides communication to an
    SSD1306 chip attached by an adapter. To actually use it, you should use
    one of the subclasses for the various interface types.

      * Device::Chip::SSD1306::I2C - I²C

      * Device::Chip::SSD1306::SPI4 - 4-wire SPI

    The reader is presumed to be familiar with the general operation of
    this chip; the documentation here will not attempt to explain or define
    chip-specific concepts or features, only the use of this module to
    access them.

METHODS

    The following methods documented with a trailing call to ->get return
    Future instances.

 $ssd->init->get

    Initialise the display after reset to some sensible defaults.

 $ssd->display( $on )->get

    Turn on or off the display.

 $ssd->display_lamptest( $enable )->get

    Turn on or off the all-pixels-lit lamptest mode.

 $ssd->send_display( $pixels )->get

    Sends an entire screen-worth of pixel data. The $pixels should be in a
    packed binary string 128 * 8 bytes long.

TODO

      * More interfaces - 3-wire SPI

      * Maintain a framebuffer. Add some drawing commands like pixels and
      lines.
