Properties

Properties not inherited from the base binding file.

Name

Type

Details

segment-offset

int

8-bit column start address for Page Addressing Mode

This property is required.

page-offset

int

Start address for Page Addressing Mode

This property is required.

display-offset

int

mapping of the display start line to one of COM0 .. COM63

This property is required.

multiplex-ratio

int

Multiplex Ratio

This property is required.

segment-remap

boolean

Last column address is mapped to first segment

com-invdir

boolean

Scan direction is from last COM output to first COM output

com-sequential

boolean

Sequential COM pin configuration

prechargep

int

Duration of the pre-charge period

This property is required.

reset-gpios

phandle-array

RESET pin.
The RESET pin of SSD1306 is active low. If connected directly the MCU pin should be configured as active low.

height

int

Height of the panel driven by the controller, with the units in pixels.

This property is required.

width

int

Width of the panel driven by the controller, with the units in pixels.

This property is required.

supply-gpios

phandle-array

GPIO specifier that controls power to the device.

This property should be provided when the device has a dedicated
switch that controls power to the device.  The supply state is
entirely the responsibility of the device driver.

Contrast with vin-supply.

vin-supply

phandle

Reference to the regulator that controls power to the device.
The referenced devicetree node must have a regulator compatible.

This property should be provided when device power is supplied
by a shared regulator.  The supply state is dependent on the
request status of all devices fed by the regulator.

Contrast with supply-gpios.  If both properties are provided
then the regulator must be requested before the supply GPIOS is
set to an active state, and the supply GPIOS must be set to an
inactive state before releasing the regulator.
