NAME
     ssdfb - OLED/PLED framebuffer device driver

SYNOPSIS
     options FONT_SPLEEN5x8
     ssdfb* at iic? addr ?
     ssdfb* at iic? addr 0x3c
     ssdfb* at iic? addr 0x3d flags 0x102

DESCRIPTION
     The ssdfb driver provides wsdisplay(4) support for OLED/PLED framebuffer
     modules based on one of the following controller chips:

              Solomon Systech Ltd SSD1306

              Sino Wealth Electronic Ltd SH1106

     The following products (controller + panel assemblies) are supported:

              0x01: Generic SSD1306 modules using default settings

              0x02: Generic SH1106 modules using default settings

              0x03: Adafruit Industries, LLC product 938 (128x64)

              0x04: Adafruit Industries, LLC product 931 (128x32)

     The flags value can contain one or more of the following, bitwise OR'ed:

              0x0??: Exactly one product id from the above list

              0x100: indicates that the display is mounted upside down and
               flips the screen

              0x200: enable inverse video

              0x400: forcibly attach as console

HISTORY
     An ssdfb driver first appeared in OpenBSD 6.4 and later in NetBSD 9.0.

AUTHORS
     The ssdfb driver was written by Tobias Nygren <tnn@NetBSD.org>.

     It was inspired by (and shares its name with) the OpenBSD driver written
     by Patrick Wildt <patrick@blueri.se> but does not share any code.

BUGS
     Some modules can be reconfigured to attach via spi(4), typically by
     moving surface mount zero ohm resistors.  This is currently not
     supported.
