Introduction

HoneyGUI is a graphics display framework independently developed by Realtek. It is an open-source embedded graphical user interface (GUI) library specifically designed for resource-constrained microcontrollers and embedded systems. HoneyGUI is lightweight, feature-rich, and highly customizable, making it widely used in consumer electronics, home appliances, medical devices, and smartwatches.

HoneyGUI provides a PC-based simulation environment, allowing developers to quickly develop and debug applications without relying on embedded hardware platforms. Furthermore, HoneyGUI can be used in conjunction with Realtek's proprietary front-end design tool RVD to achieve visual programming.

HoneyGUI currently supports the following two efficient APP development methods:

1. C/C++ API development

   • Developers can directly utilize the C/C++ API based on the RealGUI display engine to construct applications.
   • This approach offers the highest level of flexibility and system performance control, suitable for complex applications with high performance requirements.

2. Front-end low-code development

   • Develop front-end applications using JavaScript and XML.
   • It is recommended to use RVisualDesigner to quickly build beautiful UI interfaces through dragging and dropping components and visual configuration, enabling low-code development and significantly improving development efficiency.
   • The low-code development approach for the front end offers advantages in rapid development and iteration, making it particularly suitable for rapid prototyping and small-scale application development.

The HoneyGUI framework has excellent portability and can run on various chips and operating systems. This release provides a PC Windows version.

Versioning

HoneyGUI follows a four-part version numbering scheme:

Format: v{MAJOR}.{MINOR}.{PATCH}.{BUILD}

• MAJOR: Major architectural changes or product-level updates
• MINOR: API changes (including breaking API changes)
• PATCH: Bug fixes and minor improvements
• BUILD: Build number (typically 0)

Current Version: v2.1.1.0

Version Examples

• v2.1.1.0 - Current release
• v1.2.0.0 - Major feature updates
• v1.0.19.0 - Maintenance releases

Special Releases

Some versions include the .RVD suffix (e.g., v1.1.1.0.RVD), indicating releases specifically tailored for the RVisualDesigner tool integration.

Version Information

The project uses tool/git_generate_version.py to automatically generate version header files containing:

• Version tag
• Branch name
• Commit hash
• Build date
• Repository status

Installation on Windows

Install Compiler

Download the MinGW-w64 toolchain, extract it to drive C, and add it to the system environment variable Path.

1. MinGW-w64 Download
2. Extract and copy to directory: C:\mingw64
3. Add an environment variable: C:\mingw64\bin
   • Open the Start Menu and search for Advanced system settings.
   • Display System Properties and then go to the Advanced tab.
   • Click the Environment Variables button.
   • In the User variables section, find and select the Path variable, then click Edit.
   • Click New and add C:\mingw64\bin.
   • Click OK to close all dialogs.

Install Python

Python 3.9.7 has been tested.

Install Scons

Open a CMD window and execute the following command to install the Python scons library:

> pip install scons==4.4.0

Install Kconfiglib

Install kconfiglib for configuration management:

> pip install kconfiglib

Configure Application (Menuconfig)

Before compiling, you can use the menuconfig graphical configuration tool to select the sample application to run. This configuration is common to both SCons and CMake build systems.

Using Menuconfig for Configuration

Execute the following commands in the win32_sim directory:

> cd win32_sim
> menuconfig ../Kconfig.gui

After executing the command, the graphical configuration interface will open:

Menuconfig Configuration Interface

Operation Instructions

1. Use arrow keys to move up and down to select items

2. Use spacebar or Enter key to deselect/select configuration items

3. Select Select HoneyGUI Demo (Watch Turnkey Demo 410x502) to enter application configuration

4. Select the sample application to run:

   • Watch Turnkey Demo 410x502: Watch application example (410x502 resolution)
   • GUI Demo 800x480: Dashboard application example (800x480 resolution)
   • Other available sample applications

Menuconfig Application Configuration Interface

5. Press ESC key to return to the previous menu
6. Select < s > to save configuration to .config file
7. Select < q > to exit the configuration interface

Configuration File Description

After configuration is complete, a .config file will be automatically generated in the HoneyGUI\win32_sim directory. The build system (SCons or CMake) will automatically read this configuration file and compile the corresponding application according to the configuration.

Note: If you do not use menuconfig for configuration, the build system will use the default configuration or an existing .config file.

After installing the MinGW-w64 toolchain and scons library, you can launch the application through multiple methods.

Startup by CMD (Scons)

Open a CMD window in the HoneyGUI folder, then run the following commands to start the application.

> cd win32_sim
> scons
> cd ..
> .\win32_sim\gui.exe

The scons command performs the build process, then execute gui.exe to run the application.

Launch Application

Startup by CMD (CMake)

Dependencies

• CMake (tested version 3.31.2): https://cmake.org/download/

• MinGW-w64: As described above

Initialize Build Environment

Execute in the HoneyGUI folder:

> cd win32_sim
> mkdir build
> cd build
> cmake -G "MinGW Makefiles" ..

Configure Application

To change the application configuration, refer to the Configure Application (Menuconfig) section above, and execute the menuconfig ../Kconfig.gui command in the win32_sim directory.

Compile Project

Execute in the HoneyGUI\win32_sim\build folder:

> cmake -G "MinGW Makefiles" ..
> mingw32-make -j 32

During compilation, CMake will automatically:

• Read the configuration from the .config file
• Select the corresponding application source code based on the configuration
• Automatically process binary resource files (.bin files) required by the application
• Generate the executable file gui.exe

Run Program

Execute in the HoneyGUI folder:

> .\win32_sim\build\gui.exe

Startup by VSCode

Install VSCode

• Download VSCode
• Install C/C++ Extension

Open Project

• Click the HoneyGUI.code-workspace file

Run Project

After entering the VSCode interface, you can select the Run and Debug option, then click the Run button.
