DS1302走时不准？
// DS1302_Serial_Easy (C)2010 Henning Karlsen// web: http://www.henningkarlsen.com/electronics
//
// A quick demo of how to use my DS1302-library to
// quickly send time and date information over a serial link
//
// I assume you know how to connect the DS1302.
// DS1302:CE pin -> Arduino Digital 2
// I/O pin -> Arduino Digital 3
// SCLK pin-> Arduino Digital 4
#include <DS1302.h>
// Init the DS1302
DS1302 rtc(5, 6, 7);
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(MONDAY); // Set Day-of-Week to FRIDAY
rtc.setTime(12, 0, 0); // Set the time to 12:00:00 (24hr format)
rtc.setDate(6, 1, 2015); // Set the date to August 6th, 2010
}
void loop()
{
// Send Day-of-Week
Serial.print(rtc.getDOWStr());
Serial.print(" ");
// Send date
Serial.print(rtc.getDateStr());
Serial.print(" -- ");
// Send time
Serial.println(rtc.getTimeStr());
// Wait one second before repeating :)
delay (1000);
}
为什么走的时间跟设置的不一致啊？？？ 换个库试试. https://github.com/msparks/arduino-ds1302 DS1302模块与Arduino之间连线要短，试试看 这东西放1个星期能差1个小时出来。。。。很正常。买 3231会好很多。
