Product states
List normal, transitional, warning, error, locked, and unavailable states, plus the control action that moves between them.
Consumer electronics solution
LVGL interfaces for consumer electronics products
Turn an early UI draft into a clear embedded interface with agreed product states, controls, animation behavior, verification, and maintainable source.
See the STM32 hair dryer interface case for a 240 x 240 circular display with animated modes.
01 / Define
Map the product before drawing screens
A useful interface specification connects visual decisions to the operating model instead of treating each screen as a separate picture.
Display and input
Confirm resolution, orientation, color depth, display interface, touch or physical input, viewing distance, and expected ambient conditions.
Assets and localization
Provide source artwork, fonts, animation references, language sets, units, truncation rules, and any assets that must be generated or licensed.
02 / Build
Build interaction around real device limits
We align the approved design with the target memory, refresh, storage, display, input, and communication constraints.
Reusable UI structure
Shared components, style tokens, state mappings, and predictable navigation reduce drift as the product grows.
Animation and feedback
Motion is specified by trigger, duration, loop behavior, interruption rules, and resource impact before it becomes part of acceptance.
Data and controls
UI states are connected to representative data and input events so the demo can cover normal and edge paths.
03 / Transfer
Leave the product team with an operable system
The handoff is planned before development so design, implementation, protocol, and integration context stay aligned.
Design source
Approved screen designs, component states, assets, and interaction notes are transferred with the implementation.
Working LVGL source
The agreed screens and behaviors are delivered as maintainable source for the confirmed environment.
Integration context
Communication protocol notes, assumptions, build instructions, and known boundaries support the customer team after release.
