一 概述

鬧鐘，顧名思義，即在未來某個時刻提醒做某件事情。在嵌入式開發中，尤其是物聯網領域。

在對功耗要求不高的場景中，鬧鐘可以使用定時器實現。MCU還可以使用系統滴答定時器SYSTicks實現。

在低功耗場景中，建議使用RTC實時時鐘實現，因為在低功耗場景中，大多數主控都可以做到低功耗情況下保持RTC的運行。同時RTC鬧鐘超時后，可以喚醒主控，進行下一步業務，例如聯網等。

紅豆版本中，鬧鐘使用定時器實現。

二 定時器是什么

1.什么是定時器

定時器是SoC的常見外設

（1）定時器和計數器。計數器是用來計數的（每隔一個固定時間會計一個數）；因為計數器的計數時間周期是固定的，因此到了一定時間只要用計數值x計數時間周期，就可以得到一個時間段，這個時間段就是我們定的時間（這就是定時器）。

（2）定時器/計數器作為SoC的外設，主要用來實現定時執行代碼的功能。定時器相對于SoC來說，就好象鬧鐘相對于人來說意義一樣。

2.定時器有什么用

（1）定時器可以讓SoC在執行主程序的同時，具有計時功能（通過定時器），到了一定時間（計時結束）后，定時器會產生中斷提醒CPU，CPU會去處理中斷并執行定時器中斷的ISR。從而去執行預先設定好的事件。

（2）定時器就好象是CPU的一個秘書一樣，這個秘書專門管幫CPU來計時，并到時間后提醒CPU要做某件事情。所以CPU有了定時器之后，只需預先把自己xx時間之后必須要做的事情綁定到定時器中斷ISR即可，到了時間之后定時器就會以中斷的方式提醒CPU來處理這個事情。

3.定時器的原理

（1）定時器計時其實是通過計數來實現的。 定時器內部有一個計數器，這個計數器根據一個時鐘（這個時鐘源來自于ARM的APB總線 66MHz，然后經過時鐘模塊內部的分頻器來分頻得到）來工作。每隔一個時鐘周期，計數器就計數一次，定時器的時間就是計數器計數值×時鐘周期。

（2）定時器內部有1個寄存器TCNT，計時開始時我們會把一個總的計數值（初值）放入TCNT寄存器中，然后每隔一個時鐘周期（假設為1ms）TCNT中的值會自動減1（硬件自動完成，不需要CPU軟件去干預），直到TCNT中減為0的時候，TCNT就會觸發定時器中斷。

（3）定時時間是由2個東西共同決定的：一個是TCNT中的計數值，一個是時鐘周期，兩者的乘積即為最終定時的時間。

三 SYSTicks是什么

嵌入式開發中的SysTick（System Tick Timer）是一個簡單的定時器，它為嵌入式系統提供了一個周期性的中斷或事件，通常用于操作系統任務調度、時間跟蹤或其他需要定時功能的場合。SysTick是ARM Cortex-M微控制器內核的一部分，但類似的概念也存在于其他架構中。

四 RTC是什么

1.簡介

實時時鐘是一個獨立的定時器。RTC模塊擁有一組連續計數的計數器，在相應軟件配置下，可提供時鐘日歷的功能，計數頻率常為秒。修改計數器的值可以重新設置系統當前的時間和日期。

2.特性

（1）32位的可編程計數器，可用于較長時間段的測量

（2）能在MCU掉電后運行

（3） 低功耗

3.后備寄存器和RTC寄存器特性

（1）部分寄存器寫保護：RTC_PRL、RTC_ALR、RTC_CNT和RTC_DIV寄存器不會被系統復位。

（2）數據存儲功能：RTC和后備寄存器不會被系統或電源復位源復位；當從待機模式喚醒時，也不會被復位。后備寄存器可用于保存掉電時的數據。

（3）獨立工作：RTC和后備寄存器通過一個開關供電，在VDD有效時該開關選擇VDD供電，否則由VBAT引腳供電。在VBAT供電時仍可繼續工作。

（4）2個獨立復位：APB1接口由系統復位；RTC核心只能由后備域復位；

三 使用場景

定時和服務器通信，可以用到鬧鐘功能。每次鬧鐘超時通知后，和服務器通信，通信完畢，再次設置一個下次通信的鬧鐘。

定時采集傳感器數據，

4 dtu_clk1_timer_callback

鬧鐘1回調函數，響鈴后去做一些事情

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();
    //按照配置輸出對應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實戰

4.1 創建一個Demo

復制20.2_at_xtu示例工程，到同一個文件夾下，修改文件名為20.9_di_xtu，如圖：

4.2 修改makefile

增加文件組件所在目錄頭文件路徑，和源文件路徑，以及一些宏定義，如圖：

-D是makefile中定義宏定義必要的前綴，可以搜索相關makefile學習文章學習相關知識。

DTU_BASED_ON_TCP 表示當前是TCP模式，當前組件使用需要am.h中包含一些對應。

DTU_TYPE_5X6 表示使用SOM板貼片5x6卡，可以使用其它卡，修改為對應宏定義就可以。

DTU_UART_115200_BAUD 表示使用115200波特率

DTU_TYPE_JSON_INCLUDE 表示把JSON功能包含進來

4.3 增加頭文件

使用代碼編輯器，將新建的工程文件加入代碼編輯器中，打開main.c，修改main.c，加入am.h頭文件，如圖：

4.4 修改代碼

示例使用的是板載5x6卡，用戶的硬件可能是使用外置卡，或者是三合一全網通卡，因為硬件上三種卡使用的模組SIM卡接口不一樣（外置卡SIM1，5x6卡和三合一卡SIM2），所以，需要通過一個全局變量來制定SIM卡硬件接口。

extern外部變量SDK_INIT_SIM_SELECT_VALUE，這里判斷了是否使用外置卡，這個宏定義在Makefile里面定義。

在Phase1Inits_enter中，宏定義判斷是否要包含對SDK_INIT_SIM_SELECT_VALUE變量的修改。

在Phase2Inits_exit 調用文件組件提供的對外API，如圖：

4.5 編譯

在SDK根目錄打開命令行，輸入命令.build.bat -l .amaziot_bloom_os_sdksamplelibraries20.13_clk_xtu

4.6 生成固件

參考入門中開發工具，生成工具。

4.7 查看現象

固件下載到模組后，發送CLK 配置AT指令，觀察AT串口信息，超時后Debug口會出現DO1輸出高的信息

觸發di后，使用查看命令

根據實驗現象，用戶需要實現自己的AT指令，只需要參考組件中的例子，按照自己需求修改，

本文章源自奇跡物聯開源的物聯網應用知識庫Cellular IoT Wiki，更多技術干貨歡迎關注收藏Wiki：Cellular IoT Wiki 知識庫（https://rckrv97mzx.feishu.cn/wiki/wikcnBvAC9WOkEYG5CLqGwm6PHf）

歡迎同學們走進AmazIOT知識庫的世界！

這里是為物聯網人構建的技術應用百科，以便幫助你更快更簡單的開發物聯網產品。

Cellular IoT Wiki初心：

在我們長期投身于蜂窩物聯網 ODM/OEM 解決方案的實踐過程中，一直被物聯網技術碎片化與產業資源碎片化的問題所困擾。從產品定義、芯片選型，到軟硬件研發和測試，物聯網技術的碎片化以及產業資源的碎片化，始終對團隊的產品開發交付質量和效率形成制約。為了減少因物聯網碎片化而帶來的重復開發工作，我們著手對物聯網開發中高頻應用的技術知識進行沉淀管理，并基于 Bloom OS 搭建了不同平臺的 RTOS 應用生態。后來我們發現，很多物聯網產品開發團隊都面臨著相似的困擾，于是，我們決定向全體物聯網行業開發者開放奇跡物聯內部沉淀的應用技術知識庫 Wiki，期望能為更多物聯網產品開發者減輕一些重復造輪子的負擔。

Cellular IoT Wiki沉淀的技術內容方向如下：

奇跡物聯的業務服務范圍：基于自研的NB-IoT、Cat1、Cat4等物聯網模組，為客戶物聯網ODM/OEM解決方案服務。我們的研發技術中心在石家莊，PCBA生產基地分布在深圳、石家莊、北京三個工廠，滿足不同區域&不同量產規模&不同產品開發階段的生產制造任務。跟傳統PCBA工廠最大的區別是我們只服務物聯網行業客戶。

連接我們，和10000+物聯網開發者一起 降低技術和成本門檻

讓蜂窩物聯網應用更簡單~~

哈哈你終于滑到最重要的模塊了，

千萬不！要！劃！走！忍住沖動！~
