Overview
emWin is SEGGER's embedded graphics library. It provides tools and APIs for creating GUIs on microcontroller platforms, and it is capable of empowering even resource-constrained microcontroller-based systems to run high-quality interactive user interfaces. It supports both simple and complex high-resolution displays, is designed for embedded systems, and can be adapted to any display size, display controller, or CPU.
Key features
emWin simplifies the process of creating visually appealing and user-friendly interfaces, reducing development time and effort. It provides an easy-to-use and powerful API as well as functions for tasks such as drawing shapes, rendering images, handling touch inputs, managing display buffers, and interfacing with display hardware. emWin is a crucial element for embedded projects that require GUIs, data visualization, or any form of visual feedback.
Great Portability and Versatility
Users can integrate emWin into new hardware platforms and a variety of microcontroller architectures. It runs on any platform, from low-end microcontrollers to high-end processors with varying capabilities. It also supports any microcontroller, display, or display controller, and it enables UI functionality on headless devices through VNC
High-Quality Drawing Operations
emWin core functionalities are designed for precise rendering of all graphical elements, including lines, shapes, gradients, and bitmaps. Included here are the rendering functions for the window manager, widget library, and font support. Developers can apply anti-aliasing to all rendering functions to ensure that any element (including fonts) is displayed with smooth edges. Furthermore, this also applies to alpha blending operations.
Low Memory Footprint
Optimized for performance and memory use, emWin is tailored to the constraints and requirements of embedded applications. With efficient rendering algorithms and memory-management strategies, it minimizes resource consumption while also maintaining responsive UI performance.
Use Cases
emWin can be adapted to any application, from battery-powered single-chip products with basic graphical requirements, to high-end embedded systems requiring extreme levels of performance and sophisticated animations. A state-of-the-art GUI solution in the embedded inndustry, emWin is used in a variety of areas, including industrial control systems, applications within the Internet of Things, networking, consumer electronics, safety-critical devices, automotive system, medical devices, and avionics systems.

How emWin Works
emWin provides a comprehensive API as well as a range of tools for creating visually appealing and interactive interfaces. It supports real-time updates, custom graphics, and touch inputs, and the graphics library is compatible with multiple platforms - enabling it to run on a variety of operating systems and hardware architectures.
emWin is compatible with single-task and multitask environments, and it supports many IDEs, popular toolchains, and proprietary operating systems (e.g., SEGGER's embOS RTOS). Developers can use emWin's what-you-see-is-what-you-get tools (such as the AppWizard) to design GUIs without doing any coding, and they can create custom widgets via callbacks or the owner-draw function.
emWin is compatible with capacitive touch systems, and it automatically manages data transfer and processing (typically x and y coordinates and an identifier from a touch controller). Additionally, emWin offers the option to calibrate a touch controller. Due to its modular design, emWin is highly versatile can be integrated into a wide range of applications.
Award Winning GUL Design Tool: AppWizard
SEGGER's award winning AppWizard enables the creation of impressively efficient and high-quality GUIs on any embedded system, and it does so in the simplest possible way - without the need to write any code. AppWizard enables limitless creativity in embedded systems GUI design.
