原创 DS1302的电路图[转]

贴上一小段代码：

void DS1302_GetTime(SYSTEMTIME *Time)
{
 unsigned char ReadValue;
 ReadValue = Read_DS1302(DS1302_SECOND);
 Time->Second = ((ReadValue&0x70)>>4)*10 + (ReadValue&0x0F);
 ReadValue = Read_DS1302(DS1302_MINUTE);
 Time->Minute = ((ReadValue&0x70)>>4)*10 + (ReadValue&0x0F);
 ReadValue = Read_DS1302(DS1302_HOUR);
 Time->Hour = ((ReadValue&0x70)>>4)*10 + (ReadValue&0x0F);
 ReadValue = Read_DS1302(DS1302_DAY);
 Time->Day = ((ReadValue&0x70)>>4)*10 + (ReadValue&0x0F);
 ReadValue = Read_DS1302(DS1302_WEEK);
 Time->Week = ((ReadValue&0x70)>>4)*10 + (ReadValue&0x0F);
 ReadValue = Read_DS1302(DS1302_MONTH);
 Time->Month = ((ReadValue&0x70)>>4)*10 + (ReadValue&0x0F);
 ReadValue = Read_DS1302(DS1302_YEAR);
 Time->Year = ((ReadValue&0x70)>>4)*10 + (ReadValue&0x0F);
}
