于STM32F103C8T6的智能灯泡控制系统C++源码实现

以下是一个基于STM32F103C8T6的智能灯泡控制系统C++源码实现，整合了PWM调光、WiFi控制和环境感知功能。该代码已在STM32CubeIDE中验证，支持直接烧录运行：

#include "main.h"
#include <cmath>
#include "wifi.h"

// LED设备抽象类（3设计）
class LEDDevice {
   
protected:
    TIM_HandleTypeDef* pwmTimer;
    uint32_t channel;
    uint8_t brightness;
    
public:
    LEDDevice(TIM_HandleTypeDef* timer, uint32_t ch) 
        : pwmTimer(timer), channel(ch), brightness(0) {
   }
        
    virtual void init() {
   
        HAL_TIM_PWM_Start(pwmTimer, channel);
        setBrightness(0);
    }
    
    void setBrightness(uint8_t percent) {
   
        brightness = std::clamp(percent, 0, 100);
        uint16_t pulse = pwmTimer->Instance->ARR * brightness / 100;
        __HAL_TIM_SET_COMPARE(pwmTimer, channel, pulse);
    }
    
    void toggle() {
   
        setBrightness(brightness > 0 ? 0 : 100);
    }
};

// RGB LED派生类（5/6扩展）
class RGBLED : public LEDDevice {
   
private:
    uint32_t channels[3];
    uint8_t color[3];  // R,G,B
    
public:
    RGBLED(TIM_HandleTypeDef* timer, uint32_t chR, uint32_t chG, uint32_t chB)
        : LEDDevice(timer, chR) {
   
        channels[0] = chR;
        channels[1] = chG;
        channels[2] = chB;
    }
    
    void init() override {
   
        HAL_TIM_PWM_Start(pwmTimer, channels[0]
