+# Renesas
+The [HMI-Board](https://bit.ly/3I9nfUo) development board SDK now comes with LVGL integration for quick evaluation. Simply download the [SDK](https://github.com/RT-Thread-Studio/sdk-bsp-ra6m3-hmi-board/tree/main/projects/hmi-board-lvgl) for the supported motherboard and you’ll be on your way to creating your next GUI application in no time. For more information, check out the [Software design description](https://github.com/RT-Thread-Studio/sdk-bsp-ra6m3-hmi-board/blob/main/projects/hmi-board-lvgl/README.md).
+
+## Creating new project with LVGL
+It is recommended to start your project by downloading the HMI-Board SDK example project. It comes fully equipped with LVGL and dave-2d support (if the modules are present), so you won’t need to do any additional integration work.
+
+## HW acceleration for Renesas RA6M3 platforms
+For RA6M3 platforms, hardware acceleration can be achieved using the dave-2d GPU, depending on the platform used. Each accelerator has its own context, allowing them to be used individually or simultaneously in LVGL’s multithreading mode.
+
+### Dave-2d accelerator
+LVGL can offload several drawing features to the dave-2d engine, freeing up the CPU for other operations while dave-2d runs. An RTOS is required to block the LVGL drawing thread and switch to another task or suspend the CPU for power savings. Supported draw callbacks can be found in “src/draw/renesas/lv_gpu_d2_ra6m3.c”.

+    ra_2d_draw_ctx->base_draw.draw_letter = lv_draw_gpu_letter;
+```
+
+### Features supported:
+    All operations can be used in conjunction with optional transparency.
+
+  - RGB565 and ARGB8888 color formats
+  - Area fill with color
+  - BLIT (BLock Image Transfer)
+  - Color conversion
+  - Rotate and scale
+  - Alpha blending
+  - Bilinear filtering
+  - RTOS integration layer
+  - Default RT-Thread code provided
+  - Subpixel exact placement
+
+### Basic configuration:
+  - Select Renesas dave-2d engine in lv_conf.h: Set `LV_USE_GPU_RA6M3_G2D` to 1
+  - Set referenced header file in lv_conf.h: `#define LV_GPU_RA6M3_G2D_INCLUDE "hal_data.h"`
+
+### RT-Thread Example:
+
+```c
+#define COLOR_BUFFER  (LV_HOR_RES_MAX * LV_VER_RES_MAX)
+
+static lv_disp_drv_t disp_drv;
+
+/*A static or global variable to store the buffers*/
+static lv_color_t buf_1[COLOR_BUFFER];
+```
+
+- After initializing your peripherals (such as SPI, GPIOs, and LCD) in the `lv_port_disp_init()` function, you can initialize LVGL using [`lv_init()`.](https://docs.lvgl.io/master/API/core/lv_obj.html#_CPPv47lv_initv) Next, register the frame buffers using `lv_disp_draw_buf_init()` and create a new display driver using `lv_disp_drv_init()`.
+
+```c
+/*Initialize `disp_buf` with the buffer(s). With only one buffer use NULL instead buf_2 */
+lv_disp_draw_buf_init(&disp_buf, buf_1, RT_NULL, COLOR_BUFFER);
+lv_disp_drv_init(&disp_drv); /*Basic initialization*/
+
+/*Set the resolution of the display*/
+disp_drv.hor_res = LV_HOR_RES_MAX;
+disp_drv.ver_res = LV_VER_RES_MAX;
+
+/*Set a display buffer*/
+disp_drv.draw_buf = &disp_buf;
+
+/*Used to copy the buffer's content to the display*/
+disp_drv.flush_cb = disp_flush;
+
+/* Initialize GPU module */
+lv_port_gpu_hw_init();
+
+/*Finally register the driver*/
+lv_disp_drv_register(&disp_drv);
+```
+
+* To run LVGL, you’ll need to create a thread. You can find examples of how to do this using RT-Thread in the `env_support/rt-thread/lv_rt_thread_port.c` file.
+
+```c

-TODO
+Arm-2D is not a GPU but **an abstraction layer for 2D GPUs dedicated to Microcontrollers**. It supports all Cortex-M processors ranging from Cortex-M0 to the latest Cortex-M85. 
 
+Arm-2D is an open-source project on Github. For more, please refer to: https://github.com/ARM-software/Arm-2D.
+
+
+
+## How to Use
+
+In general, you can set the macro `LV_USE_GPU_ARM2D` to `1`in `lv_conf.h` to enable Arm-2D acceleration for LVGL.
+
+If you are using **[CMSIS-Pack](https://github.com/lvgl/lvgl/tree/master/env_support/cmsis-pack)** to deploy the LVGL. You don't have to define the macro `LV_USE_GPU_ARM2D` manually, instead, please select the component `GPU Arm-2D` in the **RTE** dialog. This step will define the macro for us. 
+
+
+
+## Design Considerations
+
+As mentioned before, Arm-2D is an abstraction layer for 2D GPU; hence if there is no accelerator or dedicated instruction set (such as Helium or ACI) available for Arm-2D, it provides negligible performance boost for LVGL (sometimes worse) for regular Cortex-M processors. 
+
+**We highly recommend you enable Arm-2D acceleration for LVGL** when:
+
+- The target processors are **Cortex-M55** and/or **Cortex-M85**
+- The target processors support **[Helium](https://developer.arm.com/documentation/102102/0103/?lang=en)**.
+- The device vendor provides an arm-2d compliant driver for their propriotory 2D accelerators and/or customized instruction set.
+- The target device contains [DMA-350](https://community.arm.com/arm-community-blogs/b/internet-of-things-blog/posts/arm-corelink-dma-350-next-generation-direct-memory-access-for-endpoint-ai)
+
