前面已经发了智能家居入门的1、2、3了,在实际开发中一般都会使用到实时操作系统,这里就以FreeRTOS为例子,使用标准库。记录由裸机转到实时操作系统所遇到的问题以及总体流程。相较于裸机,系统实时性强了很多,小程序下发的指令基本立马执行,没有啥延迟,调整任务的挂起时间,可以进一步提高系统效率
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,无偿)
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-;ink、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:https://blog.csdn.net/m0_71523511/article/details/135887108
