lightbulb

Example of the component espressif/lightbulb_driver v1.2.0
# 球泡灯应用示例

本示例演示了如何在 ESP32 系列芯片上使用 `lightbulb_driver` 组件开发一个球泡灯应用程序。具体演示的功能如下:

- 可选择基于 WS2812 驱动、 PWM 驱动、BP5758D 驱动的演示
- 可配置不同的灯珠组合方案
- 所有光色切换启用了渐变效果
- 输出预置的光色方案
- 基于最底层驱动 API 的控制

## 如何使用该示例

### 硬件需求

1. 通过 `idf.py menuconfig` 选择需要演示的驱动,并进行驱动配置

2. 硬件连接:
    - 对于 WS2812 驱动,仅需要将信号端口连接到所配置的 GPIO 上。
    - 对于 PWM 驱动,需要将 R G B 三个信号端口正确连接到所配置的 GPIO 上,错误的连接将导致颜色错误。
    - 对于 BP5758D 驱动,需要将时钟信号与数据信号正确连接到所配置的 GPIO 上。

    > IIC 类调光驱动工作时需要接入市电,**连接时请断开市电,谨防触电**。

### 编译和烧写

1. 进入 `lightbulb` 目录:

    ```linux
    cd ./esp-iot-solution/examples/lighting/lightbulb
    ```

2. 使用 `idf.py` 工具设置编译芯片,随后编译下载,指令分别为:

    ```linux
    # 设置编译芯片
    idf.py idf.py set-target esp32

    # 编译并下载
    idf.py -p PORT build flash
    ```

    请将 `PORT` 替换为当前使用的端口号

### 示例输出结果
