好的,以下是基于STM32的烟雾报警器排风设计的完整代码:
```c
#include "stm32f10x.h"
#define SMOKE_SENSOR_PIN GPIO_Pin_0
#define SMOKE_SENSOR_PORT GPIOA
#define FAN_PIN GPIO_Pin_1
#define FAN_PORT GPIOA
#define BEEP_PIN GPIO_Pin_2
#define BEEP_PORT GPIOA
#define SMOKE_THRESHOLD 500
void GPIO_Configuration(void)
{
GPIO_InitTypeDef GPIO_InitStructure;
//使能GPIOA外设时钟
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);
//配置烟雾传感器引脚
GPIO_InitStructure.GPIO_Pin = SMOKE_SENSOR_PIN;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AIN;
GPIO_Init(SMOKE_SENSOR_PORT, &GPIO_InitStructure);
//配置排风设备引脚
GPIO_InitStructure.GPIO_Pin = FAN_PIN;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_Init(FAN_PORT, &GPIO_InitStructure);
//配置蜂鸣器引脚
GPIO_InitStructure.GPIO_Pin = BEEP_PIN;
GPIO_Init(BEEP_PORT, &GPIO_InitStructure);
}
void ADC_Configuration(void)
{
ADC_InitTypeDef ADC_InitStructure;
//使能ADC1外设时钟
RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE);
//配置ADC1外设
ADC_InitStructure.ADC_Mode = ADC_Mode_Independent;
ADC_InitStructure.ADC_ScanConvMode = DISABLE;
ADC_InitStructure.ADC_ContinuousConvMode = ENABLE;
ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_None;
ADC_InitStructure.ADC_DataAlign = ADC_DataAlign_Right;
ADC_InitStructure.ADC_NbrOfChannel = 1;
ADC_Init(ADC1, &ADC_InitStructure);
//配置ADC1通道
ADC_RegularChannelConfig(ADC1, ADC_Channel_0, 1, ADC_SampleTime_239Cycles5);
//启动ADC1
ADC_Cmd(ADC1, ENABLE);
//校准ADC1
ADC_ResetCalibration(ADC1);
while(ADC_GetResetCalibrationStatus(ADC1));
ADC_StartCalibration(ADC1);
while(ADC_GetCalibrationStatus(ADC1));
}
int main(void)
{
GPIO_Configuration();
ADC_Configuration();
while(1)
{
//启动ADC1转换
ADC_SoftwareStartConvCmd(ADC1, ENABLE);
//等待转换完成
while(!ADC_GetFlagStatus(ADC1, ADC_FLAG_EOC));
//读取烟雾传感器数据
uint16_t smoke_data = ADC_GetConversionValue(ADC1);
//烟雾传感器数值大于阈值,触发报警
if(smoke_data > SMOKE_THRESHOLD)
{
//打开排风设备
GPIO_SetBits(FAN_PORT, FAN_PIN);
//打开蜂鸣器
GPIO_SetBits(BEEP_PORT, BEEP_PIN);
}
else
{
//关闭排风设备
GPIO_ResetBits(FAN_PORT, FAN_PIN);
//关闭蜂鸣器
GPIO_ResetBits(BEEP_PORT, BEEP_PIN);
}
}
}
```
这段代码主要是完成了GPIO和ADC的初始化配置,然后通过读取烟雾传感器的数据,判断是否触发报警,如果触发报警则打开排风设备和蜂鸣器,反之则关闭。需要注意的是,这里的烟雾传感器数据读取和阈值判断需要根据具体的硬件和传感器型号进行调整。
