零知开源快速入门28-DS1302时钟模块实验

本实验使用DS1302时钟模块进行演示时间日期相关的功能应用。

一、工具原料

电脑，windows系统
零知开发板
micro-usb线
DS1302模块

二、硬件连接

1、硬件连接示意图

2、实际连接

三、方法步骤

1、打开零知实验室软件开发工具，然后新建项目，输入以下代码：

2、按照之前的方式先【编译】，然后【上传】到开发板中。

复制
							
	#include "DS1302.h"
	 
	// Init the DS1302
	DS1302 rtc(2, 3, 4);//rst,data,clk
	 
	// Init a Time-data structure
	Time t;
	 
	void setup()
	{
	        // Set the clock to run-mode, and disable the write protection
	        rtc.halt(false);
	        rtc.writeProtect(false);
	         
	        // Setup Serial connection
	        Serial.begin(9600);
	         
	        // The following lines can be commented out to use the values already stored in the DS1302
	        rtc.setDOW(THURSDAY);        // Set Day-of-Week to FRIDAY
	        rtc.setTime(15, 30, 0);     // Set the time to 12:00:00 (24hr format)
	        rtc.setDate(27, 6, 2019);   // Set the date to August 6th, 2010
	}
	 
	void loop()
	{
	        // Get data from the DS1302
	        t = rtc.getTime();
	         
	        // Send date over serial connection
	        Serial.print("The Date: ");
	        Serial.print(t.date, DEC);
	        Serial.print(".");
	        Serial.print(rtc.getMonthStr());
	        Serial.print(". ");
	        Serial.print(t.year, DEC);
	        Serial.println(".");
	         
	        // Send Day-of-Week and time
	         
	         
	        Serial.print("Day of Week:");
	        Serial.println(t.dow, DEC);
	         
	        Serial.print("The Time:");
	        Serial.print(t.hour, DEC);
	        Serial.print(" : ");
	        Serial.print(t.min, DEC);
	        Serial.print(" : ");
	        Serial.print(t.sec, DEC);
	        Serial.println(" .");
	         
	        // Send a divider for readability
	        Serial.println("  -  -  -  -  -  -  ");
	         
	        // Wait one second before repeating :)
	        delay (1000);
	}	
						
							
						

四、成果展示

将上述代码验证后上传到零知板，就可以看到测试结果了。
