开发板的 LED 显示检测例程

例程简介

ADF 从功能角度为定义了一系列常见的 显示模式，在不同硬件环境下，用户可使用统一接口 display_service_set_pattern 设置显示模式。目前已添加的驱动 LED 方式有 PWM、AW2013、IS3x、WS2812。

本例程主要演示如何操作 LED 模式，以及验证所有 LED 是否正常工作，更多信息请参考 ADF 入门指南。

环境配置

硬件要求

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。

编译和下载

IDF 默认分支

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。

配置

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

编译和下载

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》。

如何使用例程
