I have already done that yesterday see 2 posts above the picture,normski001 wrote:in serial monitor it says 24/4/13 14:22:38 DOW3
ant then it increases by 1 second a time.
so how do i get that to show on the screen
Code: Select all
/* Include the wire library */
#include "Wire.h"
/* Include the Hobby Components RTC library */
#include <HCRTC.h>
/* Define the I2C addresses for the RTC and EEPROM */
#define I2CDS1307Add 0x68
/* Include the standard LiquidCrystal library */
#include <LiquidCrystal.h>
/* DIO pin definitions */
#define LCD_DATA4 4 /* LCD data DIO pin 4 */
#define LCD_DATA5 5 /* LCD data DIO pin 5 */
#define LCD_DATA6 6 /* LCD data DIO pin 6 */
#define LCD_DATA7 7 /* LCD data DIO pin 7 */
#define LCD_RESET 8 /* LCD Reset DIO pin */
#define LCD_ENABLE 9 /* LCD Enable DIO pin */
#define LCD_BACKLIGHT 10 /* LCD backlight DIO pin */
/* Initialise the LiquidCrystal library with the correct DIO pins */
LiquidCrystal lcd(LCD_RESET, LCD_ENABLE, LCD_DATA4, LCD_DATA5, LCD_DATA6, LCD_DATA7);
/* Used in example as an index pointer */
byte index;
/* Create an instance of HCRTC library */
HCRTC HCRTC;
void setup()
{
Serial.begin(9600);
/* Use the RTCWrite library function to set the time and date.
Parameters are: I2C address, year, month, date, hour, minute, second,
day of week */
HCRTC.RTCWrite(I2CDS1307Add, 13, 4, 24, 14, 21, 0, 3);
/* Set the correct display size (16 character, 2 line display) */
lcd.begin(16, 2);
}
void loop()
{
/* Continuously read the current time and date from the RTC */
while(true)
{
/* Read the current time from the RTC module */
HCRTC.RTCRead(I2CDS1307Add);
lcd.setCursor(0,0);
lcd.print("Seconds:");
lcd.setCursor(0,1);
lcd.print(HCRTC.GetSecond());
/* Wait a second before reading again */
delay(1000);
}
}
Sorted!
