solomon,ssd1306fb (on i2c bus)¶

Vendor: Solomon Systech Limited

Description¶

SSD1306 128x64 dot-matrix display controller on I2C bus

Properties¶

Properties not inherited from the base binding file.

Name	Type	Details
`height`	`int`	Height in pixel of the panel driven by the controller This property is required.
`width`	`int`	Width in pixel of the panel driven by the controller This property is required.
`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.
`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.

Properties inherited from the base binding file, which defines common properties that may be set on many nodes. Not all of these may apply to the “solomon,ssd1306fb” compatible.

Name	Type	Details
`reg`	`array`	device address on i2c bus This property is required. See Important properties for more information.
`label`	`string`	Human readable string describing the device (used as device_get_binding() argument) This property is required. See Important properties for more information.
`status`	`string`	indicates the operational status of a device Legal values: `'ok'`, `'okay'`, `'disabled'`, `'reserved'`, `'fail'`, `'fail-sss'` See Important properties for more information.
`compatible`	`string-array`	compatible strings This property is required. See Important properties for more information.
`reg-names`	`string-array`	name of each register space
`interrupts`	`array`	interrupts for device See Important properties for more information.
`interrupts-extended`	`compound`	extended interrupt specifier for device
`interrupt-names`	`string-array`	name of each interrupt
`interrupt-parent`	`phandle`	phandle to interrupt controller node
`clocks`	`phandle-array`	Clock gate information
`clock-names`	`string-array`	name of each clock
`#address-cells`	`int`	number of address cells in reg property
`#size-cells`	`int`	number of size cells in reg property
`dmas`	`phandle-array`	DMA channels specifiers
`dma-names`	`string-array`	Provided names of DMA channel specifiers
`io-channels`	`phandle-array`	IO channels specifiers
`io-channel-names`	`string-array`	Provided names of IO channel specifiers
`wakeup-source`	`boolean`	Property to identify that a device can be used as wake up source. When this property is provided a specific flag is set into the device that tells the system that the device is capable of wake up the system. Wake up capable devices are disabled (interruptions will not wake up the system) by default but they can be enabled at runtime if necessary.
