Offline-map enablement for an MCU-class HMI

Map rendering and interaction designed around the memory and performance limits of an MCU-based display.

The challenge

A connected-looking navigation experience had to work with offline assets and strict limits on memory, storage and graphics throughput.

Engineering approach

Crossware developed the platform and rendering approach needed to move map content through a constrained system efficiently. Asset preparation, caching, interaction behaviour and frame performance were refined together rather than as isolated features.
