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.

inversion-on

boolean

 
Turn on display color inverting

ready-time-ms

int

 
Time it takes for the device from power up to become responsive and
accepting commands. Defaults to 10ms (found by trial and error) if not
provided.

Default value: 10

use-internal-iref

boolean

 
Use internal Iref, not common but sometime used to save component cost.

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.
