一、BLE 蓝牙优化 - 设备名称改为动态名称 Airhub_MAC（基于BLE MAC地址） - 广播数据拆分为 ADV + Scan Response 两包 - 图片接收完成后数据直通显示（跳过SPIFFS重读，减少200-500ms延迟） - BLE耗时操作（NVS写入+导航显示）转移到独立FreeRTOS任务，避免BTC_TASK栈溢出 - 缩短BLE连接间隔（min=7.5ms, max=20ms），提升传输吞吐量 - 减少传输日志输出（每100包打印一次），提升传输速度 二、显示性能优化 - LVGL绘制缓冲区从DMA 30行改为PSRAM 120行大缓冲，减少flush次数 - CPU最大频率从160MHz提升到240MHz，提升解码性能 三、GIF动图支持（条件编译，当前默认关闭） - 实现自定义GIF播放器：Palette LUT查表 + TRUE_COLOR无Alpha + 后台线程解码流水线 - 使用 #if LV_USE_GIF 条件编译包裹所有GIF代码，sdkconfig中CONFIG_LV_USE_GIF=n时零开销 - 启用GIF时需设置 CONFIG_LV_USE_GIF=y 即可 四、图片管理优化 - BLE接收新图片后直接追加到列表（避免重扫SPIFFS目录） - SPIFFS图片扫描支持.gif扩展名（条件编译控制） 五、文档更新 - 设备运行日志：GIF性能瓶颈分析与优化方案 Co-Authored-By: Claude Opus 4.6 <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
