void settime(struct tm* datetime)
{
 uchar

void gettime(struct tm* datetime)
{
 uchar
  i2c_ibuf[16],i2c_obuf=0;
  // CIM  CT1  CT2  SEC  MIN  HOUR DAYS WDAYS MNT YR    M    H     D  W

//{0x00,0x00,0x02,0x50,0x59,0x23,0x18,0x00,0x81,0x04,0x00,0x00,0x80,0x80,0x8
3,0x00,0x00};
 i2c_MasterTransferNI(0xA2,1,&i2c_obuf,16,i2c_ibuf);
 datetime->tm_year=BCD2BIN(i2c_ibuf[8]&0x7F)+100;  //yy
 datetime->tm_mon=BCD2BIN(i2c_ibuf[7]&0x1F);    //mm
 datetime->tm_mday=BCD2BIN(i2c_ibuf[5]&0x3F);   //dd

}


Szerintem jo minden.
