继电器实现
继电器原理图
继电器采用的是5V继电器，控制端是RELAY-1
继电器代码实现
#include "relay.h"
/*
继电器 --- PA4 --- 推挽输出
*/
void JDQ_Init(void)
{
GPIO_InitTypeDef JDQ_InitStruct={0};
RCC_APB2PeriphClockCmd(JDQ1_CLK,ENABLE);
JDQ_InitStruct.GPIO_Mode= GPIO_Mode_Out_PP;//通用推挽
JDQ_InitStruct.GPIO_Speed = GPIO_Speed_50MHz;
JDQ_InitStruct.GPIO_Pin = JDQ1_PIN;
GPIO_Init(JDQ1_PORT,&JDQ_InitStruct);
JDQ1(0);
}
uint8_t GetJDQ1Sta(void)
{
return JDQ1_STA;
}
//extern dataPoint_t currentDataPoint;
void JiaoHua(uint8_t Sta)
{
JDQ1(Sta);
//currentDataPoint.valueRelay_1=Sta;
}
#ifndef _RELAY_H_
#define _RELAY_H_
#include "stm32f10x.h"
#define JDQ1_CLK RCC_APB2Periph_GPIOA
#define JDQ1_PORT GPIOA
#define JDQ1_PIN GPIO_Pin_4
#define JDQ1(X) X?(GPIO_SetBits(JDQ1_PORT,JDQ1_PIN)):(GPIO_ResetBits(JDQ1_PORT,JDQ1_PIN))
#define JDQ1_STA GPIO_ReadOutputDataBit(JDQ1_PORT,JDQ1_PIN)
void JDQ_Init(void);
#endif
继电器功能测试
#include "main.h"
typedef struct
{
uint8_t valueRelay_1;
}TestDataPoint_t;
TestDataPoint_t TestDataPoint;
int main(void)
{
NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);
USART1_Init(9600);
//printf("打印串口初始化 OK !\r\n");
SysTick_Init();
//printf("系统嘀嗒初始化 OK !\r\n");
LED_Init();
//printf("状态指示初始化 OK !\r\n");
KEY_Init();
//printf("按键配置初始化 OK !\r\n");
JDQ_Init();
//printf("继电器配置初始化 OK !\r\n");
while(1)
{
LED_Task();
if(GetKey0())
{
GPIO_TogglePin(LED1_PORT,LED1_PIN);
JiaoHua(1-TestDataPoint.valueRelay_1);
TestDataPoint.valueRelay_1 = 1-TestDataPoint.valueRelay_1;
//JiaoHua(1-currentDataPoint.valueRelay_1);
}
if(GetKey1())
{
GPIO_TogglePin(LED2_PORT,LED2_PIN);
//gizwitsSetMode(WIFI_AIRLINK_MODE);
//按键进入配网模式
}
if(GetKey2())
{
GPIO_TogglePin(LED3_PORT,LED3_PIN);
}
}
}
说明
继电器是用来打开浇花的电机的，单片机无法直接控制5V电平就用一个三极管进行转换。
测试时候定义了一个结构体
是因为接下来这个继电器需要通过机智云平台进行控制，继电器的状态要实时的跟网络上的状态保持同步。
DHT11温湿度传感器原理图
DHT11温湿度传感器驱动原理

取模数据如下
数据显示
OLED显示代码
float Temp = 0.0;//温度数据
float Humi = 0.0;//湿度数据
void OLED_Task(void)
{
static uint32_t Timer = 0;
if(SoftTimer(Timer,1000))

添加OLED显示继电器状态和WFi状态
由于屏幕显示范围有限，预留给显示关照强度的显示，就设置成了两页显示 间隔2500ms切换一次
