Hi all! I have this RTC ISL x1226 module. I found the source code by isl1208.
//device isl1208 address 0x6F
#include <Wire.h>
#include <avr/interrupt.h>
byte seconds, hours, minutes, date, months, years, statusReg;
void setup () {
pinMode(5, INPUT);
digitalWrite(5,HIGH);
attachInterrupt(0, alarmTriggered, FALLING);
interrupts();
delay(50);
Serial.begin(9600);
Wire.begin();
Wire.beginTransmission(0x6F);
Wire.write(0x07); //status register
Wire.write(0x90); //
Wire.endTransmission();
readStatusReg(statusReg);
Serial.print(statusReg,HEX); //should be 144/0x90
Serial.println("h - status register");
/*
//alarm setup
Wire.beginTransmission(0x6F);
Wire.write(0x08); //alarm register
Wire.write(0xD0);
Wire.endTransmission();
Wire.beginTransmission(0x6F);
Wire.write(0x0c); //seconds alarm register
Wire.write(0xB0); //secs
Wire.endTransmission();
*/
/*
// set time
Wire.beginTransmission(0x6F);
Wire.write(0x00); //seconds register
Wire.write(decToBcd(30)); //secs
Wire.write(decToBcd(41)); //min
Wire.write(0xA3); //hour
Wire.write(decToBcd(03)); //date
Wire.write(decToBcd(8)); //month
Wire.write(decToBcd(13)); //year
Wire.endTransmission();
Wire.beginTransmission(0x6f);
Wire.write(0x07); //status reg addr
Wire.endTransmission();
Wire.requestFrom(0x6f,1); // now get the byte of data...
byte statusReg=Wire.read();
Serial.println(statusReg);
*/
}
void loop () {
Wire.beginTransmission(0x6f);
Wire.write(0x00); //status reg addr
Wire.endTransmission();
Wire.requestFrom(0x6f,6); // now get the byte of data...
seconds=Wire.read();
minutes=Wire.read();
hours=Wire.read();
date=Wire.read();
months=Wire.read();
years=Wire.read();
hours=hours & B01111111; // remove mil time bit
Serial.print(bcdToDec(hours));
Serial.print(':');
Serial.print(bcdToDec(minutes));
Serial.print('.');
Serial.print(bcdToDec(seconds));
Serial.print(' ');
Serial.print(bcdToDec(months));
Serial.print('/');
Serial.print(bcdToDec(date));
Serial.print('/');
Serial.println(bcdToDec(years));
delay(1000);
}
byte readStatusReg(byte val){
Wire.beginTransmission(0x6f);
Wire.write(0x07); // read status reg to clr bits
Wire.endTransmission();
Wire.requestFrom(0x6f,1); // now get the byte of data...
statusReg=Wire.read();
return(statusReg);
}
byte bcdToDec(byte val)
{
return ( (val/16*10) + (val%16) );
}
byte decToBcd(byte val)
{
return ( (val/10*16) + (val%10) );
}
void alarmTriggered()
{
Serial.println("** ALARM WENT OFF! **");
}
How can I change this code to ISL x1226??? Thank's
