## 新增功能 - 图片删除：支持从 SPIFFS 彻底删除图片（物理删除 + 内存管理） - ContainerDle 管理：新增半透明圆形删除容器（含删除和返回按钮） - 状态管理：标志位模式管理 UI 状态，离开界面自动清理 ## 解决的关键问题 1. 开机闪烁 (⭐️⭐️⭐️⭐️⭐️) - 原因：LCD GRAM 保留旧数据 - 方案：背光使能前清空 GRAM（DMA 分批填充黑色，34ms） 2. 低功耗唤醒闪烁 (⭐️⭐️⭐️⭐️⭐️) - 原因：先恢复亮度后切换界面，看到旧界面 - 方案：先切换界面（背光=0）→ 延时 100ms → 恢复亮度 3. ContainerDle 状态保留 (⭐️⭐️⭐️⭐️) - 原因：LVGL 对象不销毁，状态被保留 - 方案：离开界面时主动清理（手势/按键回调中调用隐藏函数） 4. 按键回调冲突 (⭐️⭐️⭐️⭐️) - 原因：按键系统单回调限制 - 方案：统一在 main.c 管理 BOOT 按键，其他模块通过接口调用 5. 开机加载图片闪烁 (⭐️⭐️⭐️) - 原因：screen_init() 中 JPEG 解码触发渲染 - 方案：延迟到 LV_EVENT_SCREEN_LOADED 事件加载 ## 功能改动 - BOOT 按键增强：唤醒 + 退出手电筒 + 隐藏容器 + 返回 Home - 图片界面优化：支持删除当前图片并自动显示下一张 - 休眠管理优化：移除 BOOT 注册，避免回调冲突 ## 技术优化 - 资源节约：分批处理大数据（LCD GRAM 清除） - 时序优化：根据屏幕状态智能调整唤醒时序 - 模块化设计：按键集中管理 + 接口清晰 + 状态标志模式 ## 文件变更 - lcd/lcd.c: LCD GRAM 清除逻辑 - main.c: BOOT 按键统一管理 - pages/pages.c: 图片删除功能实现 - ui/screens/ui_ScreenImg.c: ContainerDle 管理 + 状态控制 - sleep_mgr/sleep_mgr.c: 按键回调优化 - ui/images: 新增删除和返回按钮图标 (s13.png, s14.png) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Hello World Example
Starts a FreeRTOS task to print "Hello World".
(See the README.md file in the upper level 'examples' directory for more information about examples.)
How to use example
Follow detailed instructions provided specifically for this example.
Select the instructions depending on Espressif chip installed on your development board:
Example folder contents
The project hello_world contains one source file in C language hello_world_main.c. The file is located in folder main.
ESP-IDF projects are built using CMake. The project build configuration is contained in CMakeLists.txt files that provide set of directives and instructions describing the project's source files and targets (executable, library, or both).
Below is short explanation of remaining files in the project folder.
├── CMakeLists.txt
├── pytest_hello_world.py Python script used for automated testing
├── main
│ ├── CMakeLists.txt
│ └── hello_world_main.c
└── README.md This is the file you are currently reading
For more information on structure and contents of ESP-IDF projects, please refer to Section Build System of the ESP-IDF Programming Guide.
Troubleshooting
-
Program upload failure
- Hardware connection is not correct: run
idf.py -p PORT monitor, and reboot your board to see if there are any output logs. - The baud rate for downloading is too high: lower your baud rate in the
menuconfigmenu, and try again.
- Hardware connection is not correct: run
