-So pay extra attention to these:
+Examples
+~~~~~~~~
 
-- :cpp:func:`lv_display_set_buffers(display, buf1, buf2, buf_size_byte, mode)` is more or less the equivalent of ``lv_disp_draw_buf_init(&draw_buf_dsc, buf1, buf2, buf_size_px)`` from v8, however in **v9 the buffer size is set in bytes**.
-- In v9 ``lv_color_t`` is always RGB888 regardless of ``LV_COLOR_DEPTH``.
-- ``lv_conf.h`` has been changed a lot, so don't forget to update it from ``lv_conf_template.h``
-- Be sure ``<stdint.h>`` is **not** included in ``lv_conf.h``. In v9 we have some assembly parts for even better performance and a random include there would mess up the assembly part.
-- The online image converter in not updated yet. Until that use `LVGLImage.py <https://github.com/lvgl/lvgl/blob/master/scripts/LVGLImage.py>`__ .
-- Run time dithering is rendering due its complexity and lack of GPU support. Smaller dithered and tiled images can be used as background images as a replacement.
-- STM32's DMA2D (Chrom-ART) support is removed for now. It will be added again when an official partnership starts with ST too.
-- SJPG was removed as the original TJPGD support decoding tile-by-tile. (typically a tile is 8x8 pixels)
-- ``LV_COLOR_DEPTH 8`` is not supported yet. In v8 it meant RGB332, in v9 it will be used for L8.

-- Built-in support LVGL's, C library, and other ``stdlib``s
-- Better parallel rendering architecture. See the details :ref:`here <porting_draw>`
-- Built in display and touch driver: SDL, Linux Frame buffer,  NuttX LCD and touch drivers, ST7789 and ILI9341 driver are available and more will come soon
-- :ref:`observer` allows to bind data to UI elements and create a uniform and easy to maintain API

+CI and tests

-General API changes
--------------------
-
-
-Although `lv_api_map.h <https://github.com/lvgl/lvgl/blob/master/src/lv_api_map.h>`__ address most of the refactoring we encourage you to use the latest API directly.
-
--  ``lv_disp_...`` is renamed to ``lv_display_...``
--  ``btn_...`` is renamed to ``button_...``
--  ``btnmatrix_...`` is renamed to ``buttonmatrix_...``
--  ``img_...`` is renamed to ``image_...``
--  ``zoom`` is renamed to ``scale``
--  ``angle`` is renamed to ``rotation``
--  ``scr`` is renamed to ``screen``
--  ``act`` is renamed to ``active``
--  ``del`` is renamed to ``delete``
--  ``col`` is renamed to ``column``
--  ``lv_obj_clear_flag`` is renamed to ``lv_obj_remove_flag``
--  ``lv_obj_clear_state`` is renamed to ``lv_obj_remove_state``
--  ``lv_coord_t`` was removed and replaced by ``int32_t``
-
-New color format management
----------------------------
-
--  ``LV_IMG_CF_...`` was replaced by ``LV_COLOR_FORMAT_...``
--  ``LV_COLOR_DEPTH 24`` is supported for RGB888 rendering
--  ``lv_color_t`` always means RGB888
-
-Display API
------------
-
--  ``lv_disp_drv_t`` and ``lv_disp_draw_buf_t`` was removed
--  To create a display and set it up:
-
-.. code:: c
-
-   lv_display_t * disp = lv_display_create(hor_res, ver_res)
-   lv_display_set_flush_cb(disp, flush_cb);
-   lv_display_set_buffers(disp, buf1, buf2, buf_size_in_bytes, mode);
-
--  Note that now **buf size is in bytes and not pixels**
--  ``mode`` can be:
-
-   -  ``LV_DISPLAY_RENDER_MODE_PARTIAL`` This way the buffers can be
-      smaller then the display to save RAM. At least 1/10 screen sized
-      buffer(s) are recommended.
-   -  ``LV_DISPLAY_RENDER_MODE_DIRECT`` The buffer(s) has to be screen
-      sized and LVGL will render into the correct location of the
-      buffer. This way the buffer always contain the whole image. With 2
-      buffers the buffers’ content are kept in sync automatically. (Old
-      v7 behavior)
-   -  ``LV_DISPLAY_RENDER_MODE_FULL`` Just always redraw the whole
-      screen. With 2 buffers is a standard double buffering.
-
--  Similarly to the widgets, now you can attach events to the display
-   too, using ``lv_display_add_event()``
--  ``monitor_cb`` is removed and ``LV_EVENT_RENDER_READY`` event is
-   fired instead
--  Instead of having display background color and image,
-   ``lv_layer_bottom()`` is added where any color can be set or any
-   widget can be created.
--  The target color format can be adjusted in the display in runtime by calling
-   ``lv_display_set_color_format(disp, LV_COLOR_FORMAT_...)``
--  ``LV_COLOR_16_SWAP`` is removed and ``lv_draw_sw_rgb565_swap()`` can be called manually
-   in the ``flush_cb`` if needed to swap the in-place.
--  ``disp_drv.scr_transp`` was removed and
-   ``lv_display_set_color_format(disp, LV_COLOR_FORMAT_NATIVE_ALPHA)``
-   can be used instead
--  ``set_px_cb`` is removed. You can can convert the rendered image in the ``flush_cb``.
--  For more details check out the docs
-   `here /porting/display>`__ and
-   `here /overview/display>`__.
-
-Indev API
----------
-
--  Similarly to the display ``lv_indev_drv_t`` was removed and an input
-   device can be created like this:
--  Similarly to the widgets, now you can attach events to the indevs
-   too, using ``lv_indev_add_event()``
--  The ``feedback_cb`` was removed, instead ``LV_EVENT_PRESSED/CLICKED/etc``
-   events are sent to the input device
-
-.. code:: c
-
-   lv_indev_t * indev = lv_indev_create();
-   lv_indev_set_type(indev, LV_INDEV_TYPE_...);
-   lv_indev_set_read_cb(indev, read_cb);

+Renesas
+=======
+
+`Renesas <https://renesas.com/>`__ is an official partner of LVGL.
+Therefore, LVGL contains built-in support for `Dave2D <https://lpccs-docs.renesas.com/DA1470x/UM-B-157_DA1470x-GPU-API-Manual/files/doc/overview-txt.html>`__ (the GPU of Renesas)
+and LVGL also hosts ready-to-use Renesas projects.
+
+Dave2D
+------
+
+Dave2D is capable of accelerating most of the drawing operations of LVGL:
+
+- Rectangle drawing, even with gradients
+- Image drawing, scaling, and rotation
+- Letter drawing
+- Triangle drawing
+- Line drawing
+
+As Dave2D works in the background, the CPU is free for other tasks. In practice, during rendering, Dave2D can reduce the CPU usage by half or to one-third, depending on the application.
+
+Certified boards
+----------------
+
+LVGL has `certified <https://lvgl.io/certificate>`__ one Renesas board so far (more will come soon).

+
+Get started with the Renesas ecosystem
+--------------------------------------
+
+The official IDE of Renesas is called `e² studio <https://www.renesas.com/us/en/software-tool/e-studio?gad_source=1&gclid=CjwKCAjw5ImwBhBtEiwAFHDZx2V3lumaenbyJnc5Ctrclr_lEQM3G22iZgB-4F92OVLCI7xmzp1YQRoCcRgQAvD_BwE>`__. As it's Eclipse-based, it runs on Windows, Linux, and Mac as well.
+
+To get started, just download and install e² studio.
+
+Getting started with LVGL
+-------------------------
+
+LVGL provides a ready-to-use project for the `EK-RA8D1 <https://www.renesas.com/us/en/products/microcontrollers-microprocessors/ra-cortex-m-mcus/ek-ra8d1-evaluation-kit-ra8d1-mcu-group>`__ development board. Its main features from the HMI's point of view are:
+
+- 480MHz, Arm Cortex®-M85 core
+- 2MB Code Flash, 1MB SRAM
+- MIPI DSI & Parallel Graphics Expansion Ports
+- 4.5 Inch backlit TFT display, 16.7M display colors
+- 480x854 pixels resolution
+
+To get a ready-to-use project, clone the [lv_renesas](https://github.com/lvgl/lv_renesas.git) repository:
+
+.. code:: shell
+  git clone https://github.com/lvgl/lv_renesas.git --recurse-submodules
+
+After that, *Import* ``lv_ek_ra8d1`` into e² studio, build the project, and flash it.
+
+Note that on the ``SW1`` DIP switch (middle of the board) 7 should be ON, all others are OFF.
+
+Modify the project
+------------------
+
+Open a demo
+~~~~~~~~~~~
+
+In `LVGL_thread_entry <https://github.com/lvgl/lv_renesas/blob/master/lv_ek_ra8d1/src/LVGL_thread_entry.c>`__, the demos are automatically enabled based on the settings in `lv_conf.h <https://github.com/lvgl/lv_renesas/blob/master/lv_ek_ra8d1/src/lv_conf.h>`__.
+
+You can disable all demos (or just comment them out) and call some ``lv_example_...()`` functions, or add your custom code.
+
+Configuration
+~~~~~~~~~~~~~
+
+``lv_conf.h`` contains the most important settings for LVGL. Namely:
+
+- ``LV_COLOR_DEPTH`` to set LVGL's default color depth
+- ``LV_MEM_SIZE to`` set the maximum RAM available for LVGL
+- ``LV_USE_DAVE2D`` to enable the GPU
+
+
+``configuration.xml`` contains the settings for the board and the MCU. By opening this file, all the hardware and software components can be customized in a visual way.
+
+
+Support
+-------
+
+In case of an problems or questions open an issue in the `lv_renesas <https://github.com/lvgl/lv_renesas/issues>`__ repository.

+----------------
+
+The Chinese calendar is a traditional cultural tool that integrates elements 
+such as the lunar calendar, solar terms, and traditional festivals. It is 
+widely used in Chinese social life, helping people understand the dates of 
+the lunar calendar, arrange festival activities, and inherit the excellent 
+traditional culture of the Chinese nation. Whether in families, businesses, 
+or education, the Chinese calendar plays an irreplaceable role, enabling 
+people to better understand and appreciate the charm of Chinese traditional 
+culture.
