一、简单智能家居小项目
本项目把 DHT11 温湿度采集、光照检测、OLED 显示、直流电机 PWM 调速和蓝牙串口控制整合到同一套 51 单片机程序中。重点不是增加新外设，而是练习多模块接线、引脚分配、定时任务和通信协议之间的协同。
1.1 项目功能介绍
| 功能 | 代码中的接口 | 作用 |
|---|---|---|
| DHT11 | P1.2 | 读取温度和湿度；该引脚也与板载 LED3 复用 |
| 光照数字量 | SUN=P3.7 | 根据光敏模块输出控制 LED4 |
| 自动照明 | LED4=P1.3 | 源码中由光照输入控制 |
| 蓝牙照明 | LED2=P1.1 | 接收 0x01/0x02 后开灯或关灯 |
| 风扇 PWM | PWM=P1.0 | 接收 0x03/0x04 后提高或降低档位 |
| OLED | SCL=P1.4、SDA=P1.5 | 显示温度、湿度和档位 |
| 蓝牙串口 | RXD=P3.0、TXD=P3.1 | 接收控制字节并回传温湿度 |
这张表也说明了一个综合项目必须先做“引脚资源表”：同一 GPIO 不能在同一时刻承担互相冲突的功能。源码中光敏自动控制的是 LED4(P1.3)，蓝牙控制的是 LED2(P1.1)，而 P1.0 专门输出风扇 PWM。
硬件可按下列数据流理解：
flowchart LR
DHT[DHT11 温湿度] --> MCU[STC89C52]
SUN[光敏模块] --> MCU
APP[手机蓝牙助手] <-->|UART 字节| BT[蓝牙串口模块]
BT <--> MCU
MCU --> OLED[OLED 显示]
MCU --> LED[LED2 / LED4]
MCU --> PWM[PWM]
PWM --> DRIVER[电机驱动级]
DRIVER --> FAN[直流风扇]
电机也不能由 GPIO 直接供电，应通过三极管或电机驱动模块放大电流，并为感性负载配置续流保护。蓝牙模块、传感器、驱动板和单片机必须共地；模块供电电压与串口逻辑电平应按器件规格确认。
1.2 项目代码分析
初始化依次完成串口、OLED、DHT11、定时器和显示内容设置。主循环承担低实时性任务，定时器中断产生 PWM，串口中断只接收控制字节：
上电
├─ 初始化 UART / OLED / DHT11 / Timer0
├─ 显示固定标题
└─ while(1)
├─ 光照输入 → LED4
├─ 到达采样时刻 → 读取 DHT11 → 显示并回传
└─ 显示风扇档位
Timer0 每 10 ms 中断
├─ 计数满 300 次 → 置温湿度采样标志（约 3 s）
└─ 软件 PWM 计数 → 控制 P1.0
UART 中断
└─ 收到 0x01～0x04 → 控制 LED2 或风扇档位
Timer0 每 10 ms 进入一次中断，tim_count 累计到 300 才置位，因此理想周期约为：
$T_{DHT}=300\times10\text{ ms}=3000\text{ ms}=3\text{ s}$
源码注释中的 1000 ms 与实际计数不一致，应按 3 s 理解。DHT11 不适合高频连续读取，用标志位降低采样频率是正确方向。
软件 PWM 使用 pwm_count 在 0～9 之间循环。计数小于 level 时输出高电平，否则输出低电平，所以占空比约为：
$D=\frac{level}{10}\times100%$
level=0～10 分别对应约 0%、10%、20%……100%。当 level=10 时，pwm_count 的 0～9 始终小于 10，所以输出保持高电平，即满占空比。
串口接收中断取得 SBUF 后，用 switch 解释一个字节：0x01 开 LED2、0x02 关 LED2、0x03 增大风扇档位、0x04 减小档位。手机助手必须选择 HEX 发送；输入 01 表示字节 0x01，若按文本发送字符 1，得到的是 ASCII 0x31，程序不会进入对应分支。
中断和主循环共同访问的标志或档位变量，在严格的嵌入式 C 工程中宜声明为 volatile，防止编译器把主循环中的读取长期缓存。中断服务函数应尽量短，只记录事件；OLED 刷新、DHT11 时序读取和长串口发送应放在主循环中执行。
项目源码还有两个值得注意的细节：
- DHT11 组装第一个数据字节前，应先把
data_byte清零，否则左移和按位或会读取不确定初值；每进入一次等待电平的超时循环前，也应把count清零，避免低电平位累计上一次计数而被误判为超时。 - OLED 的动态数字只需在数据或档位变化时刷新，无条件反复发送 I²C 数据会占用主循环时间。
1.3 实验演示
实验时先观察 OLED 的温湿度是否周期更新，再遮挡或照射光敏模块，确认 LED4 随模块数字输出变化。很多光敏数字模块的比较器输出为低电平有效，源码的逻辑是 SUN==0 时令 LED4=1；而板载 LED 若低电平点亮，此时实际表现为熄灭。判断“亮时开灯还是暗时开灯”必须同时结合传感器输出极性和 LED 有效电平，必要时交换 0/1 分支。
手机端连接蓝牙模块后建立四个按钮，并设置为 HEX 发送：
| 控制字节 | 动作 |
|---|---|
01 | LED2 点亮 |
02 | LED2 熄灭 |
03 | 风扇档位加 1，最高为 10 |
04 | 风扇档位减 1，最低为 0 |
若某一模块单独正常、组合后异常，应按“电源→共地→引脚冲突→中断时长→协议字节”的顺序检查。电机启动造成复位或温湿度数据跳变，通常优先检查供电压降、地线回路和电机干扰，而不是先怀疑业务代码。
1.4 VS Code介绍
VS Code 是通用源代码编辑器，适合浏览整个工程、跨文件搜索、安装 C 语言扩展和 AI 辅助插件。它本身不是 51 单片机编译器，也不会自动替代 Keil 的 C51 工具链；课程中主要用它阅读和整理 .c/.h 文件，实际编译、链接和烧录仍使用已经配置好的嵌入式工具链。
1.5 VS Code功能介绍
安装时可按需要勾选“添加到 PATH”“将‘通过 Code 打开’添加到文件和目录上下文菜单”等选项。打开完整工程文件夹后，左侧资源管理器能显示 main.c、各驱动目录和头文件；全局搜索可追踪函数声明、定义和调用位置。
初学者阅读综合项目时，可先从 main.c 的初始化和主循环开始，再沿 #include 与函数调用进入 DHT11、OLED、UART、Timer 等模块。不要只看单个文件，否则容易忽略宏定义的引脚、定时器初始化参数以及中断服务函数。
