+- `esp_driver_ledc` - Driver for LEDC
 
 For compatibility, the original `driver`` component is still treated as an all-in-one component by registering these `esp_driver_xyz`` components as its public dependencies. In other words, you do not need to modify the CMake file of an existing project, but you now have a way to specify the specific peripheral driver that your project depends on.

 为了兼容性，原来的 `driver` 组件仍然存在，并作为一个 “all-in-one" 的组件，将以上这些 `esp_driver_xyz` 组件注册成自己的公共依赖。换句话说，你无需修改既有项目的 CMake 文件，但是你现在多了一个途径去指定你项目依赖的具体的外设驱动。
