What is Automotive Infotainment Embedded GUI?

Automotive infotainment embedded GUI is the software layer that drives the central touchscreen in a vehicle — combining navigation, media playback, phone connectivity, climate controls, vehicle settings, and ADAS camera feeds into a single responsive interface. A modern IVI (In-Vehicle Infotainment) system must handle multi-touch gestures, animate between screens fluidly, mirror a smartphone screen via CarPlay or Android Auto, render a live rear-view or surround-view camera, and respond to voice input — all simultaneously, without blocking vehicle safety systems.

Sparklet provides the embedded GUI foundation for precisely this level of complexity. Its 3D rendering pipeline (OpenGL ES / Vulkan) on NXP i.MX 8 delivers the rich animated transitions an IVI demands, while built-in CarPlay and Android Auto support in the Flint UI Designer means these advanced features require no low-level integration code. For a broader view of Sparklet's automotive capabilities, see the automotive HMI demos page.

IVI Display Capabilities with Sparklet

Connected IVI

Build full-featured connected IVI screens — navigation with live map tiles, media player with album art transitions, Bluetooth call management, vehicle settings panel, and CAN data dashboard. Sparklet's Tab, Carousel, and ScrollView widgets provide the swipe-to-navigate UX drivers expect, with momentum scrolling, snap-to-item behaviour, and programmable inertia curves all built in. Widget layout and screen transitions are designed visually in Flint UI Designer and exported as optimised C code.

NXP i.MX 8 and i.MX RT1170 — Sparklet's IVI Platform Foundation

Sparklet has powered IVI demos on NXP i.MX 8 featuring full Android Auto operation — navigation, media controls, phone connectivity, and real-time vehicle data integration. The same framework is equally at home on the lower-cost NXP i.MX RT1170 for mid-range IVI programs, using the PXP (Pixel Pipeline) hardware for 2D acceleration and delivering smooth animated IVI UIs without requiring Linux or Android.

For premium IVI programs on NXP i.MX 8 with its Vivante GC7000 GPU, Sparklet's 3D rendering pipeline uses OpenGL ES and Vulkan to animate 3D UI elements — rotating album art, 3D map perspective, animated climate dials — at full display resolution and 60fps. 3D widget assets are imported from .obj or .fbx files in Flint and placed on screen as 3DWidget or 3DView elements. The 3D graphics page covers the full pipeline configuration.

Both platforms have validated Sparklet HALs, BSP integration notes, and demo IVI projects. Porting the IVI UI from i.MX RT1170 to i.MX 8 requires only HAL layer changes — all screen code, widget logic, and state machine transitions remain identical. The NXP embedded GUI page provides full platform specifications and HAL download instructions.

Four IVI Advantages Built Into Sparklet

From touch latency to royalty economics — the IVI requirements that Sparklet was designed to meet from the ground up.
Touch Response

Sub-50 ms Touch Latency

Sparklet processes touch events in the same render cycle, delivering responsive swipe, pinch-zoom, and long-press gestures that match smartphone expectations on automotive hardware.

Royalty Free IVI

Zero Per-Unit Royalty

Ship on every vehicle without any per-unit licence fee. Sparklet's developer-seat model means your IVI licensing cost is fixed regardless of production volume — critical for OEM and Tier 1 programs.

Flint IVI Design

Rapid IVI Prototyping with Flint

Design full IVI screen layouts, CarPlay overlays, and state machine transitions in Flint's WYSIWYG canvas. Export production-ready C code and iterate HMI reviews in hours, not weeks.

Platform Flexible

Scales from MCU to MPU

The same Sparklet codebase targets i.MX RT1170 (PXP) for mid-range IVI and i.MX 8 (Vivante GPU) for premium 3D IVI. HAL-only changes between platforms protect your HMI investment across program generations.

FAQs: Automotive Infotainment Embedded GUI

Yes. Flint UI Designer includes built-in configuration for CarPlay and Android Auto screen mirroring. The mirrored smartphone screen is rendered as a hardware layer that Sparklet composites with native vehicle UI elements — speed overlay, climate status, warning icons — without the mirroring session interfering with the vehicle GUI layer.
