ESP-IDF学习记录（4） ESP-IDF examples目录

这里我准备按照官方目录，把examples里面的东西都列出来，这篇不会写的太详细，我也刚开始学习，应该会编辑很久，当一个目录来使用。后面需要用到examples里的具体内容，再单独开一篇笔记记录下来。

有中文注释的是我研究过源码的部分。

我用的板子是esp32c3 chip with 1 CPU core(s), WiFi/BLE, silicon revision v0.4, 2MB external flash，要注意看有的demo不支持这款板子

1.get-started（开始）

Simple examples with minimal functionality. Good start point for beginners.

功能最少的示例，适合新手。

        blink

                亮灯demo,支持高低电平控制或者RBG灯控制，在menuconfig里面可配置亮灯参数。

        hello_world

                打印选用esp芯片参数，配置，版本，flash大小，延时重启。

        sample_project

                这是一个可编译工程样板，只有一个头文件和一个空的主函数。

2.bluetooth（蓝牙）

        nimble

        hci

        ble_get_started

        bluedroid

                Classic BT, BLE and coex examples using default Bluedroid host stack.

        ble 

                                contains BLE examples

                                包含蓝牙示例

                                        a2dp_sink

                                        A2DP-SINK    A2DP音频接收器

                                        本示例涉及到使用蓝牙传统配置文件A2DP用于音频流接收，AVRCP用于媒体信息通知，以及I2S用于音频流输出接口。

                                        像蓝牙扬声器这样的应用程序可以利用这个例子作为基本功能的参考。

                                        只支持不带后缀的ESP32，我的ESP32-C3不能编译

                                        a2dp_source

                        ​​​​​​​        ​​​​​​​        bt_discovery

        ​​​​​​​        ​​​​​​​        ​​​​​​​        ​​​​​​​        bt_hid_mouse_device

                                         bt_l2cap_client

                                        bt_l2cap_server

                                        bt_spp_acceptor

                                        bt_spp_initiator

                                        bt_spp_vfs_acceptor

                                        bt_spp_vfs_initiator

                                        hfp_ag

                                        hfp_hf

        ble_50 

                                 contains BLE 5.0 examples

                                包含蓝牙5.0示例

        classic_bt 

                                contains Classic BT examples

                                包含蓝牙经典例子

        coex 

                                contains Classic BT and BLE coex examples

        blufi

        esp_ble_mesh

        esp_hid_device

        esp_hid_host
