From an ultra-lightweight architecture to a powerful 3D engine, discover the features that give you complete design freedom and unmatched real-time rendering performance on any MCU or MPU.
In embedded systems development, every feature comes with a cost—in memory, CPU cycles, and development time. Generic UI frameworks often force a compromise: you can have rich visuals or efficient performance, but not both. This is where Sparklet is fundamentally different.
Our feature philosophy is built on a foundation of purpose-driven efficiency. Every capability within the Sparklet Graphics Library, from the rendering engine to the widget set, is meticulously designed to solve the unique challenges of resource-constrained hardware. We empower you to create visually stunning, responsive user interfaces for any platform—bare-metal, RTOS, or Linux—without taxing your system resources. This approach is born from over a decade of cross-domain expertise. Whether it's a safety-critical automotive cluster, a rugged industrial HMI, or a battery-powered wearable, our feature set is proven to accelerate innovation and deliver reliable, scalable, and engaging embedded UI solutions that lead the market.
Our Flint UI Designer provides a seamless "What You See Is What You Get" environment. Design, build, and test your interfaces with simple drag-and-drop functionality, dramatically reducing the design-to-code gap and enabling rapid, iterative development.
Accelerate development and reduce human error with our UML-inspired Hierarchical State Machine (HSM). Visually define complex UI logic, screen transitions, and event handling without writing a single line of C code, making your application easier to manage and debug.
Get a head start with a rich library of pre-built, production-ready widgets. From basic buttons and sliders to complex radial gauges and data charts, each widget is expertly designed and optimized for the low memory footprint required by embedded systems.
Sparklet is built from the ground up for minimal resource consumption. Its modular architecture ensures that only the necessary components are included in your final build, keeping your CPU and memory usage exceptionally low while delivering a high-performance visual experience.
Create a modern and informative user experience with a wide range of built-in animations. Effects like alpha blending, transformations, and slide/pop transitions are handled efficiently by the engine, ensuring smooth performance even on low-power MCUs.
Deliver a smooth, mobile-like experience with built-in support for touch gestures like tap, drag, flick, and swipe. Interactive widgets like carousels and swipe-to-confirm buttons come with built-in visual feedback to enhance usability and responsiveness.
Design products for a global audience. Sparklet offers comprehensive support for Unicode, right-to-left (RTL) encoding, and dynamic language switching at runtime. Our compact font management ensures multilingual applications remain memory-efficient.
When off-the-shelf isn't enough, Sparklet gives you the power to create your own. Our flexible framework allows you to design and implement fully custom widgets with unique behaviors, interactions, and visuals, ensuring your UI perfectly matches your brand's vision.
Sparklet isn't just software; it's a bridge to your hardware. Our engine is designed to harness the full potential of your target MCU or MPU, ensuring you extract every ounce of performance.
Sparklet fully leverages your hardware's graphical capabilities, from basic 2D blitting engines to powerful GPUs. With native support for industry-standard APIs like OpenGL ES and Vulkan, we offload complex rendering tasks to the hardware, resulting in higher frame rates, smoother animations, and lower CPU utilization.
By utilizing underlying hardware layers and sprite engines, Sparklet can composite multiple graphical elements with zero CPU overhead. This is ideal for complex UIs with dynamic backgrounds, and multiple pop-ups, ensuring a fluid and tear-free visual experience.
To minimize memory usage and accelerate rendering, Sparklet supports advanced techniques like Color Look-Up Tables (CLUT/palettized images), Run-Length Encoding (RLE) for compressed assets, and Swizzling for optimized memory access patterns.
Sparklet features a powerful 3D Transformation Engine with OpenGL support, allowing the creation and rendering of three-dimensional graphics. This capability is ideal for applications requiring advanced visuals and realistic representations. Support for perspective projection, rotation, and scaling enables dynamic and immersive UI effects.
Sparklet enables users to design and implement custom widgets tailored to their specific project needs. This flexibility ensures the graphical user interface aligns seamlessly with the desired design and functionality. Developers can define custom behaviors, interactions, and visuals to achieve unique UI experiences.
You know your hardware best. Sparklet provides precise, fine-grained control over the memory placement of assets, framebuffers, and hardware layers. Strategically place resources in different memory regions (e.g., internal SRAM, external DDR) to optimize bus bandwidth, reduce latency, and fine-tune system performance.
In a competitive market, a visually stunning UI is a key differentiator. Sparklet empowers you to move beyond flat interfaces and incorporate exquisite, informative, and interactive 3D content directly into your embedded GUI.
Powered by an industry-standard OpenGL ES / Vulkan-based rendering pipeline, Sparklet helps you realize the full potential of modern GPUs. Render complex 3D models imported from tools like Blender to create:
- Realistic 3D vehicle models in automotive clusters for diagnostics and ADAS visualization.Even on platforms with limited 2.5D graphics accelerators, Sparklet’s powerful transformation engine can achieve near-3D effects like perspective projection, rotation, and scaling, making your user interface more intuitive, interactive, and unforgettable.
