``ssd1325_spi`` Component
|
|
-------------------------
|
|
|
|
The ``ssd1325_spi`` display platform allows you to use
|
|
SSD1325 (`datasheet <https://cdn-shop.adafruit.com/datasheets/SSD1325.pdf>`__,
|
|
`Adafruit <https://www.adafruit.com/product/2674>`__) displays with ESPHome. Note that this
|
|
component is for displays that are connected via the 4-Wire :ref:`SPI bus <spi>`.

|
Connect CLK, DIN, CS, DC, and RST to pins on your ESP. For power, connect
|
|
VCC to 3.3V and GND to GND. Note that two jumper resistors on the back of the
|
|
display PCB may need to be moved to put the display into SPI mode.
|
|
`Adafruit <https://www.adafruit.com/product/2674>`__ has a
|
|
`guide <https://learn.adafruit.com/2-7-monochrome-128x64-oled-display-module/assembly>`__
|
|
that explains how to do this, if necessary.

Configuration variables:
|
|
************************
|
|
|
|
- **model** (**Required**): The model of the display. Options are:
|
|
|
|
- ``SSD1325 128x32`` (SSD1325 with 128 columns and 32 rows)
|
|
- ``SSD1325 128x64``
|
|
- ``SSD1325 96x16``
|
|
- ``SSD1325 64x48``
|
|
|
|
- **dc_pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The DC pin.
|
|
- **reset_pin** (*Optional*, :ref:`Pin Schema <config-pin_schema>`): The RESET pin.
|
|
- **cs_pin** (*Optional*, :ref:`Pin Schema <config-pin_schema>`): The pin on the ESP that that the CS line is connected to.
|
|
The CS line can be connected to GND if this is the only device on the SPI bus.
|
|
- **lambda** (*Optional*, :ref:`lambda <config-lambda>`): The lambda to use for rendering the content on the display.
|
|
See :ref:`display-engine` for more information.
|
|
- **update_interval** (*Optional*, :ref:`config-time`): The interval to re-draw the screen. Defaults to ``5s``.
|
|
- **pages** (*Optional*, list): Show pages instead of a single lambda. See :ref:`display-pages`.
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
|
|
Configuration examples
|
|
**********************
|
|
|
|
To utilize the grayscale capabilities of this display module, add a ``color:`` section to your YAML configuration;
|
|
please see :ref:`color <config-color>` for more details. As this is a grayscale display, it only uses the white color
|
|
element as shown below.
|
|
|
|
To use grayscale in your lambda:
|
|
|
|
.. code-block:: yaml
|
|
|
|
color:
|
|
- id: medium_gray
|
|
white: 50%
|
|
|
|
...
|
|
|
|
display:
|
|
...
|
|
lambda: |-
|
|
it.rectangle(0, 0, it.get_width(), it.get_height(), id(medium_gray));
|
|
|
|
|
|
To bring in grayscale images:
|
|
|
|
.. code-block:: yaml
|
|
|
|
image:
|
|
- file: "image.jpg"
|
|
id: my_image
|
|
resize: 120x120
|
|
type: GRAYSCALE
|
|
|
|
...
|
|
|
|
display:
|
|
...
|
|
lambda: |-
|
|
it.image(0, 0, id(my_image));
|
|
|
|
In this case, the image will be converted to grayscale (regardless of its original format) and rendered as such
|
|
when drawn on the display. Note that the original image may require some adjustment as not all images immediately
|
|
convert nicely to the 4-bit grayscale format this display supports.
|
|
|
|
Note that if ``type: GRAYSCALE`` is omitted, the image will render as a binary image (no grayscale); in this
|
|
case, a color attribute may be passed to the ``image()`` method as follows:
|
|
|
|
.. code-block:: yaml
|
|
|
|
image:
|
|
- file: "image.jpg"
|
|
id: my_image
|
|
resize: 120x120
|
|
|
|
...
|
|
|
|
display:
|
|
...
|
|
lambda: |-
|
|
it.image(0, 0, id(medium_gray), id(my_image));
|
|
|
|
This will draw the complete image with the given shade of gray.
|
|
|
|
To create a new color as needed in code:
|
|
|
|
.. code-block:: yaml
|
|
|
|
display:
|
|
...
|
|
lambda: |-
|
|
float white_intensity = 0.5;
|
|
Color variable_gray(0, 0, 0, white_intensity);
|
|
it.rectangle(0, 0, it.get_width(), it.get_height(), variable_gray);
|
|
|
|
The last argument of the ``Color`` constructor is the intensity of the white element; it is a percentage
|
|
(value of range 0 to 1). It may be defined by another variable so it is adjustable in code.
