Hi all. I wrote code for RTC x1226, bun dosn’t work (((
#include <Wire.h>
#include <avr/interrupt.h>
byte seconds, hours, minutes, date, months, years, statusReg;
byte a0,a1,a2,a3,a4,a5,a6,a7,a8,i;
byte a[64];
void setup () {
Serial.begin(9600);
Wire.begin();
Wire.beginTransmission(0x6F);
Wire.write(0xde);
// Wire.write(0x00);
Wire.write(0x3f); //Int Register
Wire.write(0x02);
Wire.endTransmission();
Wire.beginTransmission(0x6F);
Wire.write(0xde);
// Wire.write(0x00);
Wire.write(0x3f); //Int Register
Wire.write(0x06);
Wire.endTransmission();
Wire.beginTransmission(0x6F);
Wire.write(0xde);
// Wire.write(0x00);
Wire.write(0x11); //Int Register
Wire.write(0x08);
Wire.endTransmission();
delay(10);
Wire.beginTransmission(0x6F);
Wire.write(0xde);
Wire.write(0x00);
Wire.write(0x3f); //Int Register
Wire.write(0x00);
Wire.endTransmission();
}
void loop () {
Wire.beginTransmission(0x6F);
Wire.write(0xae);
// Wire.write(0x00);
Wire.write(0x00);
Wire.write(0x00);
Wire.write(55);
Wire.endTransmission();
Wire.beginTransmission(0x6F);
Wire.write(0xaf);
// Wire.write(0x00);
Wire.write(0x00);
Wire.write(0x00);
// Wire.write(55);
Serial.println(Wire.read());
Serial.println("------");
// Wire.requestFrom(0x6f,1); // now get the byte of data...
for (i=0; i<=8; i++){
a[i]=Wire.read();
Serial.print(a[i]);
Serial.print(",");
}
Wire.endTransmission();
// Serial.println(statusReg);
Serial.println("------");
delay(1000);
}
byte readStatusReg(byte val){
Wire.beginTransmission(0x6f);
Wire.write(0x3f); // read status reg to clr bits
Wire.endTransmission();
Wire.requestFrom(0x6f,1); // now get the byte of data...
statusReg=Wire.read();
return(statusReg);
}
SPI-scaner find this RTC on adress 0x6F
