Today, the machine-human interface has evolved from a single text to a graphical user interface (GUI). The graphical interface is more visually acceptable to the user and enables a WYSIWYG experience. In general, the graphical interface generally uses a touch-enabled screen to implement graphics windows, drop-down menus, dialog boxes, and their corresponding control operation logic. With the increase of user demands, the interactive interface becomes more and more intelligent and powerful. For these functions, the embedded device needs a powerful graphic display processing capability and a complete interaction system, which requires a lot of interface creation time and a large amount of code. This undoubtedly brings more pressure and challenges to developers.
Renesas Electronics has introduced the RX600 series of new RX65N/RX651 microcontrollers (MCUs) for these features of the graphical interface. This product includes an embedded TFT controller and integrated 2D graphics accelerator with advanced features. TFT display graphic design in IoT edge devices or system control applications. Selecting a display size up to WQVGA can use its large 640 KB of on-chip RAM as a display frame buffer, saving external RAM and ensuring a cost-optimized design.
At the same time, Renesas Electronics and SEGGER, a provider of hardware, software and embedded system development tools, announced that the two companies will collaborate to provide free and powerful SEGGER for commercial customers using Renesas Electronics' new RX65N/RX651 microcontrollers (MCUs). emWin GUI package. Developers developing Human Machine Interfaces (HMI) or any RX65N/RX651 device-based system will receive a free license using the emWin library version (including its full suite of tools). emWin can be used in all market segments including industrial, medical, consumer, smart home, white goods and automotive.
TFT-LCD controller
The new RX65N/RX651 products have a built-in LCDC controller and 2D graphics engine. They support WQVGA/16-bit color and VGA/8-bit color, 3-layer alpha blending, and multiple pixel formats.
The peripheral supports LCD screens in multiple data formats. The following figure illustrates the supported data formats.
The new RX65N/RX651 microcontroller (MCU) is a single-chip HMI solution for small TFT LCDs that requires no external RAM. In addition, the built-in 2D graphics engine can significantly reduce CPU load when accessing graphics data.
emWinGUI tool
Renesas Electronics, through its cooperation with SEGGER, develops a graphical interface for users with free GUI graphical software tools. All customers using the new RX651/RX65N can use the emWin GUI software on their hardware to quickly develop graphical user interface systems.
The professional GUI emWinGUI tool enables you to create a high-quality graphical user interface on the RX651/RX65N embedded system and run a stunning interactive interface on a resource-constrained microcontroller. emWin is a completely independent software product that does not rely on monitors and can be used on any monitor. The GUI emWinGUI software has the following features:
ANSI C Library
No need for RTOS
Can use any controller based monitor
Take up less RAM and ROM resources
VNC Client/Server with File Transfer
Language resource file
RTL and Bidirectional text support
Support multiple layers
Use multiple monitors at the same time
Virtual display support
Multi-buffering function to avoid flicker and tear effects
Integrated memory management system
Simulation environment

Window manager and customizable widget library
Extensive support tools
emWin embedded GUI software is compatible with single task and multitasking environments using proprietary operating systems, or with any commercial RTOS such as SEGGER's embOS. embOS is designed for ultra-low power consumption and can be used in any battery-powered application.
Licensing model
All customers using the new RX651/RX65N products can use the emWin software on their hardware at no additional cost.
Support RTOS/Compiler
Can support any RTOS, support 3 types of compilers (CCRX, GCC, IAR), support for both Speed ​​and Size compile options.
Support mode
Customers can contact Renesas Electronics FAE directly for support and can also get guidance through the SEGGER Technical Forum.
emWinGUI package
The Segger emWin GUI package has full functionality, including Release notes, API documentation, tutorials, and application examples. It also includes all license-based tools such as GUIBuilder, emWinView, emWinSPY, BmpCvt, JPEG2Movie, and more. The package also includes pre-configured projects for all new projects including WIN32 simulation. Users can quickly create their own GUI projects and simulation projects.
software download
The Segger emWin leaflet is included in the RX65N development kit, allowing users to easily find the emWin GUI as well as the download page.
