Question
f_utime
Posted on January 31, 2014 at 09:31
Anyone got any experience using the f_utime function from chan's fatfs? I've got a function that uses it to put a timestamp on a file I create on an SD card, but it returns INVALID_NAME every time. Not quite sure why. Anybody have any ideas? (Btw, I'm using a STM32F415VG if that helps). My code looks like this:
FRESULT set_timestamp (char *obj)
{
FILINFO fno;
RTC_TimeTypeDef RTC_TimeStructure;
RTC_DateTypeDef RTC_DateStructure;
RTC_GetTime(RTC_Format_BIN,&RTC_TimeStructure);
RTC_GetDate(RTC_Format_BIN,&RTC_DateStructure);
int hour = RTC_TimeStructure.RTC_Hours;
int min = RTC_TimeStructure.RTC_Minutes;
int sec = RTC_TimeStructure.RTC_Seconds;
int month = RTC_DateStructure.RTC_Month;
int mday = RTC_DateStructure.RTC_Date;
int year = RTC_DateStructure.RTC_Year;
year+=2000;
fno.fdate = (WORD)(((year - 1980) << 9) | month << 5 | mday);
fno.ftime = (WORD)(hour <<11 | min <<5 | sec/2 );
return f_utime(obj, &fno);
}
