RA Family

---

Supported boards in the RA Family:

• EK-RA8D1
• EK-RA8P1
• EK-RA6M3G
• EK-RA8D2

Run the Project

• The official IDE of Renesas is called e² studio. Because it's Eclipse-based, it runs on Windows, Linux, and Mac as well. Members of the RA family require certain versions of the Flexible Software Package (FSP). See the individual README.md files in the applicable repositories for info. FSPs can be downloaded here. Please notice from FSP version 6.0 and above, LVGL is now part of the middleware section of components. Therefore when cloning the latest versions of the supported LVGL board repositories, recursive updating of the git submodules is no longer needed.

• JLink is used for debugging, it can be downloaded here.

• Clone the ready-to-use repository for your selected board, for FSP version prior to 6.0:

  .. code-block:: shell

  git clone https://github.com/lvgl/lv_port_renesas_ek-ra8d1_gcc.git --recurse-submodules

  Downloading the .zip from GitHub doesn't work as it doesn't download the submodules.

• Clone the ready-to-use repository for your selected board, for FSP version from 6.0 and above:

  .. code-block:: shell

  git clone https://github.com/lvgl/lv_port_renesas_ek-ra8d1_gcc.git

• Open e² studio, go to File -> Import project and select General / Existing projects into workspace.

• Select the cloned folder and press Finish.

• Double-click on configuration.xml. This will activate the Configuration Window.

  Renesas' Flexible Software Package (FSP) includes BSP and HAL layer support extended with multiple RTOS variants and other middleware stacks. The components will be available via code generation, including the entry point in "main.c".

  Press Generate Project Content in the top right corner.

• Build the project by pressing Ctrl + Alt + B

• Click the Debug button (). If prompted with Debug Configurations, on the Debugger tab select the J-Link ARM as Debug hardware and the proper IC as Target Device:

  • R7FA8D1BH for EK-RA8D1

Modify the project

Open a demo

The entry point of the main task is contained in src/LVGL_thread_entry.c.

You can disable the LVGL demos (or just comment them out) and call some lv_example_...() functions, or add your own custom code.

Configuration

src/lv_conf.h (or src/lv_conf_user.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 to LVGL
• LV_USE_DAVE2D to enable the GPU

Hardware and software components can be modified in a visual way using the Configuration Window.

As of e² Studio 2025-04.1 and FSP 6.0.0, LVGL is a managed component.
