|
|
RESET pin.
The RESET pin of ST7735R is active low. If connected directly the MCU pin should be configured as active low.
This property is required. |
|
|
D/CX pin.
The D/CX pin of ST7735R is active low (transmission command byte). If connected directly the MCU pin should be configured as active low.
This property is required. |
|
|
The column offset in pixels of the LCD to the controller memory
This property is required. |
|
|
The row offset in pixels of the LCD to the controller memory
This property is required. |
|
|

Power Control 3 Parameter
Default value: |
|
|
Power Control 4 Parameter
Default value: |
|
|
Power Control 5 Parameter
Default value: |
|
|
Positive Voltage Gamma Control Parameter
This property is required. |
|
|
Negative Voltage Gamma Control Parameter
This property is required. |
|
|
Frame rate control (normal mode / full colors)
Default value: |
|
|
Frame rate control (idle mode / 8 colors)
Default value: |
|
|
Frame rate control (partial mode / full colors)
Default value: |
|
|
Column Address Set
Default value: |
|
|
Row Address Set
Default value: |
|
|
VCOM Control 1
Default value: |
|
|
Display Inversion Control
Set dot inversion or line inversion for each normal/idle/partial mode.
Default value: |
|
|
Enable Display Inversion
Make a drawing with the inverted color of the frame memory.
|
|
|
Maximum clock frequency of device's SPI interface in Hz
This property is required. |
|
|
Duplex mode, full or half. By default it's always full duplex thus 0
as this is, by far, the most common mode.
Use the macros not the actual enum value, here is the concordance
list (see dt-bindings/spi/spi.h)
0 SPI_FULL_DUPLEX
2048 SPI_HALF_DUPLEX
Legal values: |
|
|
Motorola or TI frame format. By default it's always Motorola's,
thus 0 as this is, by far, the most common format.
Use the macros not the actual enum value, here is the concordance
list (see dt-bindings/spi/spi.h)
0 SPI_FRAME_FORMAT_MOTOROLA
32768 SPI_FRAME_FORMAT_TI
Legal values: |
|
|
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.
|
|
|
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.
|
|
|
Height of the panel driven by the controller, with the units in pixels.
This property is required. |
|
|
Width of the panel driven by the controller, with the units in pixels.
This property is required. |
Deprecated properties not inherited from the base binding file.
(None)
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 “sitronix,st7735r” compatible.

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.

|
|
Power domain the device belongs to.
The device will be notified when the power domain it belongs to is either
suspended or resumed.
