Native Components
Battery Card
A semantic, read-only battery monitoring component. HARDWARE VALIDATED on the current ESP32-P4 evidence ledger.
#9 — Battery Card
A semantic, read-only battery monitoring component.
- —Portable devices
- —UPS systems
- —Industrial equipment
- —Energy storage
Inspector capabilities and presentation
- —240 × 145 default and 220 × 128 minimum stackable geometry
- —Percentage, voltage and current
- —Runtime, temperature and health
- —Charging state, icon and progress
- —Low and critical thresholds with compact mode
The component remains one serialized Canvas object. Browser Preview, Live Studio and Standalone Export consume its normalized semantic model while internal LVGL composition stays private.
Generated Runtime SDK family
FG_Set_<BatteryCard>_Percentage(float value);
FG_Set_<BatteryCard>_Voltage(float value);
FG_Set_<BatteryCard>_Current(float value);
FG_Set_<BatteryCard>_Charging(bool enabled);
FG_Set_<BatteryCard>_Health(int32_t value);
FG_Set_<BatteryCard>_Runtime(int32_t value);
FG_Set_<BatteryCard>_Temperature(float value);Interaction and UserEvents
No UserEvents are generated.Battery Card is intentionally read-only. It has no selection, acknowledgement, editing, operator controls or touch callbacks.
Where hooks exist, implement the exact declarations in 95_UserEvents.c. Runtime SDK calls never simulate user input.
Ownership boundary
ForgeUI owns semantic presentation, private LVGL composition, generated contracts, persisted identity, fixed storage and Browser/Live/Standalone alignment.
