C语言——基于stm32G030的温湿度传感器项目实验

一、功能要求：

设备自检功能：

设备上电自检（检查传感器采集是否正常， DHT11有存在响应，可以自检使用，）自检通过后，由串口打印设备状态信息。

自动控制功能：

进入自动控制模式， LCD显示温湿度信息加热片制冷片风机状态。与上位机通信（串口助手），每2s发送设备状态信息(温湿度值，风机状态，制冷片状态，加热片状态)到上位机。

阈值设置功能：

可以通过五向按键选择并调整温湿度的阈值大小。

可以通过上位机发送命令设定温湿度的阈值大小。

二、功能概述

模块	功能
LCD显示屏	显示温湿度，风机开关情况，制冷片开关情况，加热片开关情况，温湿度上下阈值
LED	三个灯分别模拟风机、制冷片，加热片。（灯亮表示开，灯灭表示关）
PA0	电池电压采集（选做）
串口	数据接收及下发数据控制
低温加热	当环境温度低于设置的阈值时，加热片启动。加热到温度阈值5度以上停止工作
高温降温	当环境温度高于设置的阈值时，制冷片启动。降温到温度阈值5度以下停止工作
除湿	当环境湿度高于设置的阈值时，风机和制冷片，加热片启动。湿度低于设置的阈值停止。

三、除湿器项目设计说明

湿度高于阈值，加热片、制冷片、风机同时工作

温度也高于某一阈值，制冷片工作

四、项目实验

1.打开stm32cube max，创建新的工程，以STM32G030C8Tx芯片建立工程，配置相关引脚。

2.完成相关配置，生成hal库函数的标准代码

3.分别将Lcd和DHT11的驱动.c文件和头文件放到生成文件中的code的Src和Inc文件中

4.完成相关代码的编写，然后完成相关实验

五、代码解析

1.延时函数

滴答计时器是向下计数的，told是获取的计数器的初值，tnow是在每次循环的开始重新获取计数器的数值；如果told大于tnow代表计数器正常运行，tcnt就加一，如果全程没有错误，等到tcnt大于计数器初值的时候退出，计数结束；

如果中途出现told小于tnow时，就代表着循环了一圈了，用重载值减去tnow现在的值，再加上tnow，还是相当于tcnt就加一，等到tcnt大于计数器初值的时候退出，计数结束，实现延时功能。

static uint32_t fac_us = 0; //us延时倍乘数void delay_init(uint8_t SYSCLK)
{fac_us = SYSCLK;
}void delay_us(uint32_t nus)//100  6800
{uint32_t ticks;uint32_t told, tnow, tcnt = 0;uint32_t reload = SysTick->LOAD; //LOAD的值ticks = nus * fac_us;            //需要的节拍数told = SysTick->VAL;             // 24  刚进入时的计数器值while (1){tnow = SysTick->VAL;//22  20  0if (tnow != told){if (tnow < told)tcnt += told - tnow; //这里注意一下SYSTICK是一个递减的计数器就可以了.elsetcnt += reload - tnow + told;told = tnow;if (tcnt >= ticks)break; //时间超过/等于要延迟的时间,则退出.}};
}
void delay_ms(uint16_t nms)
{uint32_t i;for (i = 0; i < nms; i++)delay_us(1000);
}

2.定义全局变量和主函数

初始化LCD和DHT11，开始时检验DHT11是否正常，无论是否正常都反馈；如果DHT11正常的话，读取温湿度数据。

/* USER CODE BEGIN PFP */
uint8_t humiH;
uint8_t humiL;
uint8_t tempH;
uint8_t tempL;
int tempmax=30;
int tempmin=26;
int humimax=65;
float temp;
char lcdtem[16]="";
char lcdhum[16]="";
char humiset[16]="";
char tmaxset[16]="";
char tminset[16]="";
char devh[32]="devhot: off";
char devc[32]="devcold:off";
char fun[32]="fun:    off";
char set[32]="";
char md[3]="CS";
int setmode=0;

int mode=0;
int color0=BLUE;
int color1=BLUE;
int color2=BLUE; 
/* USER CODE END PFP */

int main(void)
{/* USER CODE BEGIN 1 *//* USER CODE END 1 *//* MCU Configuration--------------------------------------------------------*//* Reset of all peripherals, Initializes the Flash interface and the Systick. */HAL_Init();/* USER CODE BEGIN Init *//* USER CODE END Init *//* Configure the system clock */SystemClock_Config();/* USER CODE BEGIN SysInit *//* USER CODE END SysInit *//* Initialize all configured peripherals */MX_GPIO_Init();MX_USART1_UART_Init();MX_TIM16_Init();MX_ADC1_Init();/* USER CODE BEGIN 2 */Lcd_Init();Lcd_Clear(BLUE);delay_init(16);//根据频率确定参数 此时16MHZFS_DHT11_Init();//自检初始化函数 检测能否正常通信 只关心起始信号的正确性 不关心后面的数据HAL_Delay(500);if(!FS_DHT11_Init()) //根据0或1的返回值 由子函数可知 0自检成功 1表示失败{printf("check ok\n");Gui_DrawFont_GBK16(15,40,YELLOW,BLUE,"check ok   ");}Lcd_Clear(BLUE);HAL_TIM_Base_Start_IT(&htim16);/* USER CODE END 2 *//* Infinite loop *//* USER CODE BEGIN WHILE */while (1){/* USER CODE END WHILE *//* USER CODE BEGIN 3 */DHT11_Read_Data(&humiH,&humiL,&tempH,&tempL);temp = tempH + tempL*0.1;HAL_UART_Receive_IT(&huart1,set,10);dev_control();send_lcd();HAL_ADC_Start(&hadc1);//启动ADC转化HAL_ADC_PollForConversion(&hadc1,1000);//等待转换完成,多通道不可用uint32_t key = HAL_ADC_GetValue(&hadc1);//获取ADC转化值HAL_ADC_Stop(&hadc1);//停止ADC转化HAL_Delay(300);}/* USER CODE END 3 */
}

3.控制函数

将控制模式分为两种，模式1控制除湿，如果湿度大于阈值，进行除湿；模式2控制升温和降温，如果大于高温阈值，就进行降温；如果小于低温阈值，就进行升温。

void dev_control()
{if(mode==1){strcpy(md,"CS");if(humiH>humimax)//除湿{HAL_GPIO_WritePin(GPIOB,GPIO_PIN_0 | GPIO_PIN_1 | GPIO_PIN_2,0);strcpy(devh,"devhot:  on");strcpy(devc,"devcold: on");strcpy(fun,"fun:     on");}else{strcpy(devh,"devhot: off");strcpy(devc,"devcold:off");strcpy(fun,"fun:    off");HAL_GPIO_WritePin(GPIOB,GPIO_PIN_0 | GPIO_PIN_1 | GPIO_PIN_2,1);}}if(mode==0){strcpy(md,"KW");if(temp>tempmax)//高温 降温{HAL_GPIO_WritePin(GPIOB,GPIO_PIN_0 | GPIO_PIN_2,1);HAL_GPIO_WritePin(GPIOB,GPIO_PIN_1,0);strcpy(devh,"devhot: off");strcpy(devc,"devcold: on");strcpy(fun,"fun:    off");}else if(temp<(tempmax-5)){strcpy(devc,"devcold:off");HAL_GPIO_WritePin(GPIOB,GPIO_PIN_1,1);}if(temp<tempmin)//低温 加热{HAL_GPIO_WritePin(GPIOB,GPIO_PIN_1 | GPIO_PIN_2,1);HAL_GPIO_WritePin(GPIOB,GPIO_PIN_0,0);strcpy(devh,"devhot:  on");strcpy(devc,"devcold:off");strcpy(fun,"fun:    off");}else if(temp>(tempmin+5)){strcpy(devh,"devhot: off");HAL_GPIO_WritePin(GPIOB,GPIO_PIN_0,1);}}
}

4.LCD数据显示

将temp等数值在屏幕中显示出来。

void send_lcd()
{sprintf(lcdtem,"Temp:%.2fC",temp);sprintf(lcdhum,"Humi:%d%%",humiH);sprintf(humiset,"HumiMax:%d%%",humimax);sprintf(tmaxset,"TempMax:%dC",tempmax);sprintf(tminset,"TempMin:%dC",tempmin);Gui_DrawFont_GBK16(5,5,YELLOW,BLUE,lcdtem);Gui_DrawFont_GBK16(100,5,WHITE,BLACK,md);Gui_DrawFont_GBK16(5,20,YELLOW,BLUE,lcdhum);Gui_DrawFont_GBK16(5,35,YELLOW,BLUE,devh);Gui_DrawFont_GBK16(5,50,YELLOW,BLUE,devc);Gui_DrawFont_GBK16(5,65,YELLOW,BLUE,fun);Gui_DrawFont_GBK16(5,80,YELLOW,color0,humiset);Gui_DrawFont_GBK16(5,95,YELLOW,color1,tmaxset);Gui_DrawFont_GBK16(5,110,YELLOW,color2,tminset);
}

5.按键控制

根据五向按键每个方向都可以产生不同参数，然后根据相应参数，进行控制阈值的改变

//上 2100-2000
//下 500-600
//左1500-1600
//右2900-3000
//中2500-2600
void change_data(int key)
{if((key>1900)&&(key<2200))//增加温度{if(low==1){tempmin++;}else if(high==1){tempmax++;}}else if((key>400)&&(key<700))//减小温度{if(low==1){tempmin--;}else if(high==1){tempmax--;}}else if((key>1400)&&(key<1700))//减小湿度{color0=BLACK;color1=BLUE;color2=BLUE;humimax--;}else if((key>2800)&&(key<3100))//增大湿度{color0=BLACK;color1=BLUE;color2=BLUE;humimax++;}else if((key>2400)&&(key<2700))//进入或退出调节模式{if(setmode == 0){setmode=1;high=1;low=0;color0=BLUE;color1=BLACK;color2=BLUE;}else if(setmode == 1){low=1;high=0;setmode=2;color0=BLUE;color1=BLUE;color2=BLACK;}else{setmode=0;color0=BLUE;color1=BLUE;color2=BLUE;}}
}
/* USER CODE END 4 */

6.输出重定向

int fputc(int ch,FILE *p)
{while(!(USART1->ISR &(1<<7)));USART1->TDR = ch;return ch;
}

7.ADC中断

void HAL_GPIO_EXTI_Rising_Callback(uint16_t GPIO_Pin)
{HAL_ADC_Start(&hadc1);//启动ADC转化HAL_ADC_PollForConversion(&hadc1,1000);//等待转换完成,多通道不可用uint32_t key = HAL_ADC_GetValue(&hadc1);//获取ADC转化值HAL_ADC_Stop(&hadc1);//停止ADC转化change_data(key);
}

8.串口响应中断

查找到相关数据，并将收到的数据转化成字符串，然后向串口发送

void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim)
{if(htim==&htim16){printf("temp = %.2fC  humi = %d%%\n %s %s %s ",temp,humiH,devh,devc,fun);}
}
void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart)
{if(strstr(set,"tempmax:")){sscanf(set,"tempmax:%d",&tempmax);printf("recvdata=%s",set);}else if(strstr(set,"tempmin:")){sscanf(set,"tempmin:%d",&tempmin);printf("recvdata=%s",set);}else if(strstr(set,"humimax:")){sscanf(set,"humimax:%d",&humimax);printf("recvdata=%s",set);}else if(strstr(set,"modeset==")){sscanf(set,"modeset==%d",&mode);printf("recvdata=%s",set);}
}
