描述

一 概述

闹钟,顾名思义,即在未来某个时刻提醒做某件事情。在嵌入式开发中,尤其是物联网领域。

在对功耗要求不高的场景中,闹钟可以使用定时器实现。MCU还可以使用系统滴答定时器SYSTicks实现。

在低功耗场景中,建议使用RTC实时时钟实现,因为在低功耗场景中,大多数主控都可以做到低功耗情况下保持RTC的运行。同时RTC闹钟超时后,可以唤醒主控,进行下一步业务,例如联网等。

红豆版本中,闹钟使用定时器实现。

二 定时器是什么

1.什么是定时器

定时器是SoC的常见外设

(1)定时器和计数器。计数器是用来计数的(每隔一个固定时间会计一个数);因为计数器的计数时间周期是固定的,因此到了一定时间只要用计数值x计数时间周期,就可以得到一个时间段,这个时间段就是我们定的时间(这就是定时器)。

(2)定时器/计数器作为SoC的外设,主要用来实现定时执行代码的功能。定时器相对于SoC来说,就好象闹钟相对于人来说意义一样。

2.定时器有什么用

(1)定时器可以让SoC在执行主程序的同时,具有计时功能(通过定时器),到了一定时间(计时结束)后,定时器会产生中断提醒CPU,CPU会去处理中断并执行定时器中断的ISR。从而去执行预先设定好的事件。

(2)定时器就好象是CPU的一个秘书一样,这个秘书专门管帮CPU来计时,并到时间后提醒CPU要做某件事情。所以CPU有了定时器之后,只需预先把自己xx时间之后必须要做的事情绑定到定时器中断ISR即可,到了时间之后定时器就会以中断的方式提醒CPU来处理这个事情。

3.定时器的原理

(1)定时器计时其实是通过计数来实现的。 定时器内部有一个计数器,这个计数器根据一个时钟(这个时钟源来自于ARM的APB总线 66MHz,然后经过时钟模块内部的分频器来分频得到)来工作。每隔一个时钟周期,计数器就计数一次,定时器的时间就是计数器计数值×时钟周期。

(2)定时器内部有1个寄存器TCNT,计时开始时我们会把一个总的计数值(初值)放入TCNT寄存器中,然后每隔一个时钟周期(假设为1ms)TCNT中的值会自动减1(硬件自动完成,不需要CPU软件去干预),直到TCNT中减为0的时候,TCNT就会触发定时器中断。

(3)定时时间是由2个东西共同决定的:一个是TCNT中的计数值,一个是时钟周期,两者的乘积即为最终定时的时间。

三 SYSTicks是什么

嵌入式开发中的SysTick(System Tick Timer)是一个简单的定时器,它为嵌入式系统提供了一个周期性的中断或事件,通常用于操作系统任务调度、时间跟踪或其他需要定时功能的场合。SysTick是ARM Cortex-M微控制器内核的一部分,但类似的概念也存在于其他架构中。

四 RTC是什么

1.简介

实时时钟是一个独立的定时器。RTC模块拥有一组连续计数的计数器,在相应软件配置下,可提供时钟日历的功能,计数频率常为秒。修改计数器的值可以重新设置系统当前的时间和日期。

2.特性

(1)32位的可编程计数器,可用于较长时间段的测量

(2)能在MCU掉电后运行

(3) 低功耗

3.后备寄存器和RTC寄存器特性

(1)部分寄存器写保护:RTC_PRL、RTC_ALR、RTC_CNT和RTC_DIV寄存器不会被系统复位。

(2)数据存储功能:RTC和后备寄存器不会被系统或电源复位源复位;当从待机模式唤醒时,也不会被复位。后备寄存器可用于保存掉电时的数据

(3)独立工作:RTC和后备寄存器通过一个开关供电,在VDD有效时该开关选择VDD供电,否则由VBAT引脚供电。在VBAT供电时仍可继续工作

(4)2个独立复位:APB1接口由系统复位;RTC核心只能由后备域复位;

三 使用场景

定时和服务器通信,可以用到闹钟功能。每次闹钟超时通知后,和服务器通信,通信完毕,再次设置一个下次通信的闹钟。

定时采集传感器数据,

4 dtu_clk1_timer_callback

闹钟1回调函数,响铃后去做一些事情

 

static void dtu_clk1_timer_callback(UINT32 tmrId)
{
    DTU_FILE_PARAM_T* dtu_file_ctx = NULL;

    dtu_file_ctx = dtu_get_file_ctx();

    uprintf("%s[%d]", __FUNCTION__, __LINE__);
//    dtu_clk1_timer_stop();
    //按照配置输出对应DO
    dtu_do_clk_timeout_write_pin(dtu_file_ctx- >clk.params[DTU_BUF_INDEX_1].num, dtu_file_ctx- >clk.params[DTU_BUF_INDEX_1].level);
}

 

4 Demo实战

4.1 创建一个Demo

复制20.2_at_xtu示例工程,到同一个文件夹下,修改文件名为20.9_di_xtu,如图:

定时器

4.2 修改makefile

增加文件组件所在目录头文件路径,和源文件路径,以及一些宏定义,如图:

-D是makefile中定义宏定义必要的前缀,可以搜索相关makefile学习文章学习相关知识。

DTU_BASED_ON_TCP 表示当前是TCP模式,当前组件使用需要am.h中包含一些对应。

DTU_TYPE_5X6 表示使用SOM板贴片5x6卡,可以使用其它卡,修改为对应宏定义就可以。

DTU_UART_115200_BAUD 表示使用115200波特率

DTU_TYPE_JSON_INCLUDE 表示把JSON功能包含进来

定时器

4.3 增加头文件

使用代码编辑器,将新建的工程文件加入代码编辑器中,打开main.c,修改main.c,加入am.h头文件,如图:

定时器

4.4 修改代码

示例使用的是板载5x6卡,用户的硬件可能是使用外置卡,或者是三合一全网通卡,因为硬件上三种卡使用的模组SIM卡接口不一样(外置卡SIM1,5x6卡和三合一卡SIM2),所以,需要通过一个全局变量来制定SIM卡硬件接口。

extern外部变量SDK_INIT_SIM_SELECT_VALUE,这里判断了是否使用外置卡,这个宏定义在Makefile里面定义。

定时器

在Phase1Inits_enter中,宏定义判断是否要包含对SDK_INIT_SIM_SELECT_VALUE变量的修改。

定时器

在Phase2Inits_exit 调用文件组件提供的对外API,如图:

定时器

4.5 编译

在SDK根目录打开命令行,输入命令.build.bat -l .amaziot_bloom_os_sdksamplelibraries20.13_clk_xtu

4.6 生成固件

参考入门中开发工具,生成工具。

4.7 查看现象

固件下载到模组后,发送CLK 配置AT指令,观察AT串口信息,超时后Debug口会出现DO1输出高的信息

定时器

触发di后,使用查看命令

欢迎同学们走进AmazIOT知识库的世界!

这里是为物联网人构建的技术应用百科,以便帮助你更快更简单的开发物联网产品。

Cellular IoT Wiki初心:

在我们长期投身于蜂窝物联网 ODM/OEM 解决方案的实践过程中,一直被物联网技术碎片化与产业资源碎片化的问题所困扰。从产品定义、芯片选型,到软硬件研发和测试,物联网技术的碎片化以及产业资源的碎片化,始终对团队的产品开发交付质量和效率形成制约。为了减少因物联网碎片化而带来的重复开发工作,我们着手对物联网开发中高频应用的技术知识进行沉淀管理,并基于 Bloom OS 搭建了不同平台的 RTOS 应用生态。后来我们发现,很多物联网产品开发团队都面临着相似的困扰,于是,我们决定向全体物联网行业开发者开放奇迹物联内部沉淀的应用技术知识库 Wiki,期望能为更多物联网产品开发者减轻一些重复造轮子的负担。

Cellular IoT Wiki沉淀的技术内容方向如下:

定时器

奇迹物联的业务服务范围:基于自研的NB-IoT、Cat1、Cat4等物联网模组,为客户物联网ODM/OEM解决方案服务。我们的研发技术中心在石家庄,PCBA生产基地分布在深圳、石家庄、北京三个工厂,满足不同区域&不同量产规模&不同产品开发阶段的生产制造任务。跟传统PCBA工厂最大的区别是我们只服务物联网行业客户。

连接我们,和10000+物联网开发者一起 降低技术和成本门槛

让蜂窝物联网应用更简单~~
