- 例程难度：
ADF 在外部 PSRAM 中创建和使用了较多堆栈任务，任务运行时候禁止进行 flash 操作。
此示例演示了 ADF 此类任务如何使用 esp_dispatcher 和 nvs_action 两种方式进行 NVS 的写入和读取的操作。
本例程支持的开发板在 $ADF_PATH/examples/README_CN.md 文档中例程与乐鑫音频开发板的兼容性表格中有标注，表格中标有绿色复选框的开发板均可运行本例程。请记住，如下面的 配置 一节所述，可以在 menuconfig 中选择开发板。
本例程支持 IDF release/v3.3 及以后的分支，例程默认使用 ADF 的內建分支 $ADF_PATH/esp-idf。
本例程默认选择的开发板是 ESP32-Lyrat V4.3，如果需要在其他的开发板上运行此例程，则需要在 menuconfig 中选择开发板的配置，例如选择 ESP32-Lyrat-Mini V1.1。
menuconfig > Audio HAL > ESP32-Lyrat-Mini V1.1
请先编译版本并烧录到开发板上，然后运行 monitor 工具来查看串口输出 (替换 PORT 为端口名称)：
idf.py -p PORT flash monitor
退出调试界面使用 Ctrl-]。
有关配置和使用 ESP-IDF 生成项目的完整步骤，请参阅 《ESP-IDF 编程指南》。
例程开始运行后，首先在 NVS 中写入字符串 “Hello, ESP dispatcher!”， 然后从 NVS 读取该字符串并打印出来，代码延迟一段时间后，再写入一个 uint8_t 类型的数，然后再读取出来，打印如下：
