前言

主控仍旧是STM32F103C8T6，实时操作系统选择的是FreeRTOS。
主要功能：
①环境信息采集并上传至微信小程序
②微信小程序下发指令控制家电
③由雨滴传感器和步进电机能够实现下雨自动收起衣服，停雨自动晒出衣服（由于驱动板和步进电机不在身边，这里代码中就用舵机来模拟，之前的项目中有用stm32来驱动步进电机，代码在另外的工程里，有需要的话可以关注我私聊）
前几篇博客：
环境信息采集（HTTP+ONENET）
智能家居（MQTT+ONENET）
智能家居（MQTT+MQTT服务器）

问题汇总

1、内存不足

将FreeRTOS移植到自己的工程项目里后(移植可以看上一篇博客)，经过测试是可以用的，但是在我将之前的net文件夹移植过来之后编译就报错了，net文件夹里是与服务器通信的一些源文件（onenet.c、esp8266.c、MqttKit.c、cJSON.c），对net文件不了解的可以看这篇博客，有介绍，或者到文章最后下载源代码自己分析代码。下面贴出错误：

经过网上查找，这是由于RAM内存不够导致的，解决办法两种：
①更换开发板，换成STM32F103ZET6或者其他RAM大的开发板，亲测可以。
②修改FreeRTOSConfig.h文件：

2、延时函数

当我将dht11的驱动代码移植过来之后，编译没有报错，抱着侥幸心理以为没问题，运行之后发现串口没有调试信息输出，然后进入调试，发现任务函数2执行到DHT11_Read_Data（）时就不往后走了，每次停止的时候都会卡在不同的函数里，还真是棘手，无从下手。经过长时间问题找寻，并没有在网上找到答案，我就一步一步调试，发现每次就是延时函数出问题：

然后追溯回延时函数实现，我怀疑是因为这个延时函数使用到了系统时钟中断，然后导致和freertos起冲突，不过我只是怀疑，并不知道具体原因，然后我就将延时函数的源文件和头文件移除，使用定时器来实现延时，成功解决。
用定时器实现的延时函数如下，用这两个函数替换dht11.c和esp8266.c中的延时函数即可：

void TIM3_Init(void)
{TIM_TimeBaseInitTypeDef TIM_TimeBaseInitStructure;RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM3,ENABLE);  ///使能TIM3时钟TIM_TimeBaseInitStructure.TIM_Period    = 50000-1; 	//自动重装载值TIM_TimeBaseInitStructure.TIM_Prescaler = 60-1;     //定时器分频TIM_TimeBaseInitStructure.TIM_CounterMode=TIM_CounterMode_Up; //向上计数模式TIM_TimeBaseInitStructure.TIM_ClockDivision=TIM_CKD_DIV1; TIM_TimeBaseInit(TIM3,&TIM_TimeBaseInitStructure);//初始化TIM3
}
//微秒级延时
void TIM3_Delayus(u16 xus)
{TIM_Cmd(TIM3,ENABLE); //启动定时器while(TIM3->CNT < xus);TIM3->CNT = 0;TIM_Cmd(TIM3,DISABLE); //关闭定时器
}
//毫秒级延时
void TIM3_Delayms(u16 xms)
{int i;for(i=0;i<xms;i++){TIM3_Delayus(1000);}
}

一、项目总体介绍

用到的设备：sg90舵机、MG946舵机、MQ-2、MQ-4、MQ-9传感器、雨滴传感器、火焰传感器、继电器、风扇、水泵、DHT11、USB转TTL、J-Link、STM32F103C8T6、Esp8266-01s、led。
①标准库移植FreeRTOS参考之前的一篇博客：https://blog.csdn.net/m0_71523511/article/details/135956912
②两个舵机由定时器二的通道0、1输出PWM进行控制，这里不会的可以参考：https://blog.csdn.net/m0_71523511/article/details/135851583
③MQ系列传感器由adc三个通道进行采集，adc知识可以看这个视频，我的代码直接搬过来改的：https://www.bilibili.com/video/BV1th411z7sn/?p=22&spm_id_from=pageDriver&vd_source=2a10d30b8351190ea06d85c5d0bfcb2a
④继电器的使用和接线参考这篇博客：https://blog.csdn.net/m0_71523511/article/details/135926339
⑤雨滴传感器和火焰传感器都直接接收DO输出口，直接读取数字量，当然也可以接AO口，用adc读取模拟量，可以自己尝试。
⑥DHT11原理可以百度也可以参考我的这篇博客里面的：https://blog.csdn.net/m0_71523511/article/details/135892908
⑦新买的esp8266-01s如果没法用的话可以参考我的这篇博客：https://blog.csdn.net/m0_71523511/article/details/135887108
