Detailed Description¶

Generic demo manager for CFBD-based embedded GUI demonstrations.

Author: CharlieChen

This module provides a unified mechanism to:

Register independent demo modules
Run a single specified demo
Run demos sequentially (queue mode)
Run demos in circular rotation (loop mode)

Design goals:

No dynamic memory allocation
Pure C, OOP-style abstraction
Easy extensibility (add a demo = add one file)

Types Documentation¶

enum CFBD_DemoRunMode¶

Enumerator	Value	Description
CFBD_DEMO_RUN_SINGLE		Run only one demo
CFBD_DEMO_RUN_QUEUE		Run demos sequentially once
CFBD_DEMO_RUN_LOOP		Run demos continuously in loop

Demo run mode.

typedef CFBD_DemoEntry¶

typedef void(* CFBD_DemoEntry) (CFBD_GraphicDevice *dev);

Functions Documentation¶

function CFBD_DemoManager_Run¶

void CFBD_DemoManager_Run(
    CFBD_GraphicDevice * dev,
    const CFBD_DemoDescriptor * demos,
    uint32_t demo_count,
    CFBD_DemoRunMode mode,
    uint32_t index
)

Run demos according to selected mode.

Parameters:

dev Graphic device
demos Demo descriptor array
demo_count Number of demos
mode Run mode
index Index used only in SINGLE mode

Run demos according to selected mode.
