HMI SDK on RZ/G series¶

The Renesas RZ/G HMI SDK is an all-in-one package that includes the necessary software for developing a Linux HMI application.

The HMI SDK provides a Linux HMI application development environment for the RZ/G Evaluation Board Kit.

• Easy-to-Use

  The HMI SDK provides a quick and easy development environment, making it easier for Linux beginners to start using a Linux MPU.

• Free of Charge

  All software in the HMI SDK is available for free.

• Ready-to-Use

  The HMI SDK includes the following GUI frameworks and libraries that are appropriate for HMI.

  • LVGL (Light and Versatile Graphics Library), which is a lightweight, free, open-source embedded graphics library.
  • Chromium, which is a free and browser-based framework for application programs with GPU.

By using the image files from the SDK, you can easily create a bootable SD card. Insert the SD card into the board, and the HMI demo will automatically start on Linux. You can then begin developing your own application with ease, as the SDK includes an installer for a cross-development toolchain. Additionally, sample applications that run on the HMI SDK Linux environment are available on our GitHub.

For more information, see Overview.

HMI Frameworks¶

The HMI SDK supports the following GUI frameworks and libraries that are appropriate for HMI. In addition, the HMI SDK provides HMI sample applications implemented by using the GUI frameworks and libraries. For more information about the applications, see Overview.

LVGL (Light and Versatile Graphics Library)¶

LVGL is the most popular free and open-source embedded graphics library to create beautiful UIs for any MCU, MPU and display type. It is a lightweight graphics library, and it works without GPU. In addition, a lot of sample applications are available. They would be helpful to users.

Chromium¶

Chromium is the most popular browser in recent years, and it is increasingly being adopted for embedded products. You can implement HTML5-based solutions using Chromium. It uses GPU for its rendering.

A browser-based GUI on Chromium (HTML5 solutions) offers several advantages:

• Feature-rich user interface
• Cross-platform compatibility
• Lower development costs
