【单片机毕业设计】【mcuclub-dz-805】基于STM32单片机的彩灯控制器
本项目基于STM32F103C8T6单片机设计开发了一款多功能彩灯控制器。系统通过3个RGB灯实现5种灯光效果模式，包括单灯渐变色循环、多灯同步变色等，可通过5个物理按键或语音识别模块（唤醒词"小远小远"）进行模式切换。硬件采用两层PCB板设计，集成TYPE-C供电接口，软件使用Keil5开发环境，逻辑程序与驱动程序分离。系统框图清晰展示了以单片机为核心的中控部分、按键/语音输

一、基本介绍
项目名：基于STM32单片机的彩灯控制器
项目编号：mcuclub-dz-805
单片机类型：STM32F103C8T6
具体功能：
1、通过3个RGB灯展示灯光
2、通过5个按键展示5种不同的模式
模式一：一个灯亮完三种颜色再换另一个灯亮
模式二：一个灯亮一个颜色，从暗到亮再到暗，然后切换下一个颜色，亮完三个颜色后再换下一个灯
模式三：三个灯一起亮一种颜色的灯，然后依次亮红、绿、蓝
模式四：三个灯同时亮一种颜色从暗到亮再到暗，然后换下一种颜色
模式五：一个灯亮一个颜色，然后切换下一个灯
3、通过语音识别SU-03T控制不同的模式”唤醒指令：小远小远
二、资料总览
实物资料
三、32单片机部分资料展示
1、实物图展示

供电接口：TYPE-C
板子类型：PCB集成板，厚度1.2，两层板（上下层覆铜接地）
器件类型：元器件基本上为插针式，个别降压芯片会使用贴片式。
2、原理图展示
软件版本：AD2013
电路连线方式：网络标号连线方式
注意：原理图只是画出了模块的引脚图，而并不是模块的内部结构图
3、PCB图展示
由原理图导出，中间有一个项目编号，隐藏在单片机底座下，插入单片机后不会看到。
两层板，上下覆铜接地。
四、系统框图
绘制软件：VISIO
本设计以STM32F103C8T6单片机为核心控制器，加上其他的模块一起组成彩灯控制器检测系统，其中包含中控部分、输入部分和输出部分。中控部分采用了STM32F103C8T6单片机，其主要作用是获取输入的部分数据，经过内部处理，控制输出部分。输入由三部分组成，第一部分是语音识别模块，通过该模块控制灯光模式；第二部分是按键模块，通过按键选择灯光模式；第三部分是供电模块，通过该模块可给整个系统进行供电。输出由一部分组成，第一部分是RGB灯模块，通过该模块模拟灯光。系统框图如图3.1所示。
五、部分程序展示
软件版本：keil5
注意：逻辑程序和驱动程序分开，分布于main.c和其他.c文件
