With GD32, the largest Arm®-based MCU product family in China, GigaDevice was first to launch MCUs containing Cortex®-M3, -M4, -M23, -M33, and -M7 cores. With this, GigaDevice achieves comprehensive coverage of mainstream microcontroller applications, from low energy to ultra-high performance, covering consumer to automotive grade whilst adopting the latest architectures, keeping costs low, and offering rapid real-time response. The GD32 family has 46 product series and more than 600 devices, maintaining excellent compatibility throughout.

SEGGER emWin is a cutting-edge, high-performance graphical user interface solution, optimized for minimum memory consumption, both in RAM and ROM, as well as for high speed and versatility. It provides high-quality graphic functions and can be adapted to any size display, physical or virtual. It is compatible with single-task and multitask environments, with a proprietary operating system or with any commercial RTOS such as SEGGER embOS and embOS-Ultra.

SEGGER award-winning AppWizard enables the creation of highly efficient and high-quality graphical user interfaces on any embedded system without requiring in-depth knowledge of the emWin graphics library or even the C language for coding.

Providing extensive ecosystem support is a crucial aspect of GigaDevice's MCUs. Utilizing the emWin tool further enhances graphical user interface solutions offered by GD32 Cortex®-M series MCU. SEGGER emWin can help developers achieve professional embedded GUI in a short time, and also has excellent performance on resource-limited platforms. In the end, the corresponding C language program code is generated, which can greatly reduce the development difficulty and the time to market. Drawing on decades of expertise in embedded technology and a comprehensive suite of tools for embedded systems, SEGGER continues to enhance the user experience for GD32 customers by offering greater convenience and efficiency. Furthermore, SEGGER will strengthen the collaboration with GigaDevice to jointly assist customers in accelerating their product launches.
