[Time] RX8025 Real-Time Clock Library
The RX8025 is a Precision Real Time Clock (RTC) Module with I2C interface. This is a library (for arduino or cpp) that handles interfacing with the RX8025 module. It is a very easy module that works fine if the module is hooked up correctly (see datasheet if needed -google is your friend-). This Realtime clock is also present on the Seeeduino Stalker and that’s how i use the rtc at this time. It works pretty well; see the example file and .zip i have provided. put the content of the .zip in your /Arduino/Libraries folder.
You can set the correct time of the RX8025 by using the method in the bottom.

Example code
This code is also already included in the .zip file
#include <wire.h>#include <rx8025.h>void setup()
{Serial.begin(9600);
RX8025.init();
}void loop()
{int rtc_sec, rtc_min, rtc_hou, rtc_wee, rtc_dat, rtc_mon, rtc_yea;
delay(1000); // There will be new values every 100ms
RX8025.getRtcTime(&rtc_sec, &rtc_min, &rtc_hou, &rtc_wee, &rtc_dat, &rtc_mon, &rtc_yea);
Serial.print(rtc_dat,DEC);
Serial.print("/");
Serial.print(rtc_mon,DEC);
Serial.print("/");
Serial.print(rtc_yea,DEC);
Serial.print(" ");
Serial.print(rtc_wee,DEC);
Serial.print(" ");
Serial.print(rtc_hou,DEC);
Serial.print(":");
Serial.print(rtc_min,DEC);
Serial.print(":");
Serial.println(rtc_sec,DEC);
}
//First define thisunsigned char RX8025_time[7]={0x00,0x52,0x13,0x01,0x11,0x04,0x11 //second, minute, hour, week, date, month, year, BCD format};
//Then call thisRX8025.setRtcTime(RX8025_time);

Hi,
The line of code that says: unsigned char RX8025_time[7]={0x00,0x52,0x13,0x01,0x11,0x04,0x11 //second, minute, hour, week, date, month, year, BCD format};
…comments out the last curly bracket and semi-colon.
Cheers,
Ed
