Every 15 minute i am logging the data into the flash using the following function
void Log_Data_In_Flash(void)
{
int iCount,sample;
char test[40];
int i;
if((giDom!=(xMonthly_Log[giMoy]->xdaily_log[giDom].idd))||(giMoy!=(xMonthly_Log[giMoy]->xdaily_log[giDom].imm))||(giYy!=(xMonthly_Log[giMoy]->xdaily_log[giDom].iyy)))
{
Erase_n_Format(giYy, giMoy, giDom);//Mismatch Erase the entire months space
}
//now let us read the daily space
Read_Daily_Data(&local_daybuf_4_log, giMoy, giDom);
sample=(giHh*60+giMin)/15;//position of the data to be written for the time
vPrintStringAndNumber("sample",sample);
local_daybuf_4_log.irf[sample]=siRain_Log;

//now log the data on the flash by writing
Write_Daily_Data(&local_daybuf_4_log,giMoy, giDom);
sample=(giHh*60+giMin)/15;//position of the data to be written for the time
}
//erasing the data and formatting
void Erase_n_Format(unsigned int iYear, unsigned int iMonth, unsigned int iDate )
{
int day,month,year,sector;
//Claculate the sector
sector=START_SEC_NO_DEF+iMonth-1;
vPrintStringAndNumber("\nSec ",sector);
__disable_irq();

//before formatting clear the local buffer by readin the erased space

please see the code above for you reference.
As i told at every 15 minute i am reading the flash.
If there is no content in the flash memory i will write the text format.
I there is right contentt in the flash memory then i will read the same and substitute the value for the particular sample.
kindly guide me further.
