# 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 以下为 WS2812 驱动测试 log: ```log W (293) lightbulb demo: Lightbulb Example Start I (303) lightbulb: set [h:0 s:100 v:100] I (303) lightbulb: 8 bit color conversion value [r:255 g:0 b:0] I (313) lightbulb: hal write value [r:255 g:0 b:0], channel_mask:7 fade_ms:0 I (323) lightbulb: --------------------------------------------------------------------- I (333) lightbulb: lightbulb driver component version: 1.0.0 I (333) lightbulb: driver name: WS2812 I (343) lightbulb: low power control: disable I (343) lightbulb: status storage: disable I (353) lightbulb: status storage delay 0 ms I (353) lightbulb: fade: enable I (363) lightbulb: fade 800 ms I (363) lightbulb: led_beads: 4 I (363) lightbulb: hardware cct: No I (373) lightbulb: precise cct control: enable I (373) lightbulb: sync change: disable I (383) lightbulb: auto on: enable I (383) lightbulb: color mode: enable I (393) lightbulb: sync change: disable I (393) lightbulb: power limit param: I (393) lightbulb: white max brightness: 100 I (403) lightbulb: white min brightness: 1 I (413) lightbulb: white max power: 100 I (413) lightbulb: color max brightness: 100 I (423) lightbulb: color min brightness: 1 I (423) lightbulb: color max power: 300 I (433) lightbulb: hue: 0, saturation: 100, value: 100 I (433) lightbulb: select works mode: color, power status: 1 I (443) lightbulb: --------------------------------------------------------------------- W (453) output_test: rainbow I (2453) lightbulb: set [h:0 s:100 v:100] I (2453) lightbulb: 8 bit color conversion value [r:255 g:0 b:0] I (2453) lightbulb: hal write value [r:255 g:0 b:0], channel_mask:7 fade_ms:800 I (4453) lightbulb: set [h:30 s:100 v:100] I (4453) lightbulb: 8 bit color conversion value [r:255 g:127 b:0] I (4453) lightbulb: hal write value [r:255 g:127 b:0], channel_mask:7 fade_ms:800 I (6453) lightbulb: set [h:60 s:100 v:100] I (6453) lightbulb: 8 bit color conversion value [r:255 g:255 b:0] I (6453) lightbulb: hal write value [r:255 g:255 b:0], channel_mask:7 fade_ms:800 ... ... ...
