stm32f103c8t6实现数字密码，环境监测，灯光管理等功能代码

以下是用STM32F103C8T6实现数字密码、环境监测、灯光管理等功能的代码框架，你可以根据你的具体需求进行修改和完善。

1. 数字密码功能代码：

#include "stm32f10x.h"

#define PASSWORD_LENGTH 6
uint8_t password[PASSWORD_LENGTH] = {1, 2, 3, 4, 5, 6};
uint8_t input_password[PASSWORD_LENGTH] = {0};

void GPIO_Configuration(void) {
    GPIO_InitTypeDef GPIO_InitStructure;
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_0 | GPIO_Pin_1 | GPIO_Pin_2 | GPIO_Pin_3;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IPU;
    GPIO_Init(GPIOA, &GPIO_InitStructure);
}

uint8_t check_password(void) {
    for (int i = 0; i < PASSWORD_LENGTH; i++) {
        if (password[i] != input_password[i]) {
            return 0;
        }
    }
    return 1;
}

int main(void) {
    GPIO_Configuration();
    uint8_t input_index = 0;
    while (1) {
        if (GPIO_ReadInputDataBit(GPIOA, GPIO_Pin_0) == RESET) {
            input_password[input_index++] = 1;
            while (GPIO_ReadInputDataBit(GPIOA, GPIO_Pin_0) == RESET);
        }
        if (GPIO_ReadInputDataBit(GPIOA, GPIO_Pin_1) == RESET) {
            input_password[input_index++] = 2;
            while (GPIO_ReadInputDataBit(GPIOA, GPIO_Pin_1) == RESET);
        }
        if (GPIO_ReadInputDataBit(GPIOA, GPIO_Pin_2) == RESET) {
            input_password[input_index++] = 3;
            while (GPIO_ReadInputDataBit(GPIOA, GPIO_Pin_2) == RESET);
        }
        if (GPIO_ReadInputDataBit(GPIOA, GPIO_Pin_3) == RESET) {
            input_password[input_index++] = 4;
            while (GPIO_ReadInputDataBit(GPIOA, GPIO_Pin_3) == RESET);
        }
        if (input_index == PASSWORD_LENGTH) {
            if (check_password()) {
                //密码正确，执行解锁操作
            } else {
                //密码错误，执行报警操作
            }
            input_index = 0;
            memset(input_password, 0, PASSWORD_LENGTH);
        }
    }
}

2. 环境监测功能代码：

#include "stm32f10x.h"
#include "dht11.h"
#include "bmp180.h"
#include "bh1750.h"

float temperature, humidity, pressure, altitude, luminance;

void GPIO_Configuration(void) {
    GPIO_InitTypeDef GPIO_InitStructure;
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);
}

int main(void) {
    GPIO_Configuration();
    DHT11_Init();
    BMP180_Init();
    BH1750_Init();
    while (1) {
        DHT11_Read_Data(&temperature, &humidity);
        BMP180_Get_Data(&pressure, &altitude);
        luminance = BH1750_Get_Luminance();
        //将温度、湿度、气压、海拔高度、光照强度等数据显示在LCD屏幕上或者通过通信接口上传到云端进行处理
        delay_ms(2000);
    }
}

3. 灯光管理功能代码：

#include "stm32f10x.h"
#include "led.h"

void PWM_Configuration(void) {
    GPIO_InitTypeDef GPIO_InitStructure;
    TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure;
    TIM_OCInitTypeDef TIM_OCInitStructure;
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);
    RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM2, ENABLE);
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_1;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);
    TIM_TimeBaseStructure.TIM_Period = 999;
    TIM_TimeBaseStructure.TIM_Prescaler = 71;
    TIM_TimeBaseStructure.TIM_ClockDivision = TIM_CKD_DIV1;
    TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
    TIM_TimeBaseInit(TIM2, &TIM_TimeBaseStructure);
    TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
    TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
    TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High;
    TIM_OCInitStructure.TIM_Pulse = 0;
    TIM_OC1Init(TIM2, &TIM_OCInitStructure);
    TIM_Cmd(TIM2, ENABLE);
}

int main(void) {
    PWM_Configuration();
    while (1) {
        for (int i = 0; i <= 999; i++) {
            TIM_SetCompare1(TIM2, i);
            delay_ms(5);
        }
        for (int i = 999; i >= 0; i--) {
            TIM_SetCompare1(TIM2, i);
            delay_ms(5);
        }
    }
}

需要注意的是，以上代码仅是一个框架，具体的实现还需要根据具体的需求进行修改和完善，例如LCD屏幕的驱动、通信接口的选择和配置等。
