Edge AI page callbacks

Functions
lv_obj_t *	page_edge_ai_create (void)
	Never called directly — registered via pm_register() as the page's create callback.
void	page_edge_ai_render (sensorhub_snapshot_t *snap)
	Receives the page manager's one 33 ms snapshot.
void	page_edge_ai_destroy (void)
	Page-manager destroy callback on navigate-away.

Detailed Description

Header: page_edge_ai.h (compiled only when BENTO_HAS_EDGE_AI = 1). Implementation: archived page_edge_ai.c (libbento_cm55.a). One page for every compiled-in DEEPCRAFT model — a hard requirement, not a style choice: PM_MAX_PAGES is 20 and the project already registers 18, so per-model pages would silently fail to register and produce dead cards.

Variant

mtb-mpy and mtb-only

Function Documentation

page_edge_ai_create()

lv_obj_t * page_edge_ai_create

(

void

)

Never called directly — registered via pm_register() as the page's create callback.

Contract

Never called directly. Registered as one member of a page_def_t callback triple via pm_register(&s_pm, PAGE_ID_EDGE_AI, &def), inside a BENTO_HAS_EDGE_AI guard. The page manager owns the lifecycle and invokes it in GFX-task context on navigation. Per the dual-file rule, the registration in sensorhub_ui.c needs a matching card in page_home.c or the page exists but cannot be reached.

    }

page_edge_ai_render()

void page_edge_ai_render

(

sensorhub_snapshot_t *

snap

)

Receives the page manager's one 33 ms snapshot.

Contract

Receives the sensorhub_snapshot_t the page manager took on its 33 ms tick — the one snapshot per tick that ipc_sensorhub_snapshot() permits. Invoked by the page manager only; GFX-task context.

page_edge_ai_destroy()

void page_edge_ai_destroy

(

void

)

Page-manager destroy callback on navigate-away.

Contract

Invoked by the page manager on navigate-away, GFX-task context, while the LVGL objects are still valid.
