setCallback() [1/2]

void FsDateTime::setCallback

(

void(*)(uint16_t *date, uint16_t *time)

dateTime

)

Set the date/time callback function

Parameters

[in]

dateTime

The user's call back function. The callback function is of the form:

void dateTime(uint16_t* date, uint16_t* time) {
  uint16_t year;
  uint8_t month, day, hour, minute, second;
 
  // User gets date and time from GPS or real-time clock here
 
  // return date using FAT_DATE macro to format fields
  *date = FAT_DATE(year, month, day);
 
  // return time using FAT_TIME macro to format fields
  *time = FAT_TIME(hour, minute, second);
}

Sets the function that is called when a file is created or when a file's directory entry is modified by sync(). All timestamps, access, creation, and modify, are set when a file is created. sync() maintains the last access date and last modify date/time.

setCallback() [2/2]

void FsDateTime::setCallback

(

void(*)(uint16_t *date, uint16_t *time, uint8_t *ms10)

dateTime

)

Set the date/time callback function

Parameters

[in]

dateTime

The user's call back function. The callback function is of the form:

void dateTime(uint16_t* date, uint16_t* time, uint8_t* ms10) {
  uint16_t year;
  uint8_t month, day, hour, minute, second;
 
  // User gets date and time from GPS or real-time clock here
 
  // return date using FAT_DATE macro to format fields
  *date = FAT_DATE(year, month, day);
 
  // return time using FAT_TIME macro to format fields
  *time = FAT_TIME(hour, minute, second);
 
  *ms10 = <tens of ms since second/1>
}

Sets the function that is called when a file is created or when a file's directory entry is modified by sync(). All timestamps, access, creation, and modify, are set when a file is created. sync() maintains the last access date and last modify date/time.
