Hi,
i try to use a SD card with my MMB for PIC32 to store some data.
This is my function:
void safeOnSD() {
strcat(&Label15_Caption, ".TXT");
fhandle = -1;
fhandle = FAT32_Open(&Label15_Caption, FILE_APPEND);
if(fhandle < 0) while(1);
FAT32_seek(fhandle, 0);
strcat(&writeBuffer, "Configuration:");
strcat(&writeBuffer, &LabelFRQ_Caption);
strcat(&writeBuffer, ",");
strcat(&writeBuffer, &LabelON_Caption);
strcat(&writeBuffer, ",");
strcat(&writeBuffer, &LabelOFF_Caption);
strcat(&writeBuffer, ",");
strcat(&writeBuffer, &LabelVOLT1_Caption);
strcat(&writeBuffer, ",");
strcat(&writeBuffer, &LabelVOLT2_Caption);
strcat(&writeBuffer, ",");
strcat(&writeBuffer, &LabelMode_Caption);
strcat(&writeBuffer, ", **END OF CONFIGURATION**");
err = FAT32_Write(fhandle, &writeBuffer, sizeof(writeBuffer));
if(err < 0) while(1);
err = FAT32_Close(fhandle);
if(err < 0) while(1);
DrawScreen(&Screen1);
}
After a first use of it, it generates a file with the name of my Label15_Caption and the contend of writeBuffer.
This i also can see on mi PC when i plug in the SD card.
After this i like to manipulate the data for a second file. Then i call the same function, but now it only generate a file with the new name from Label15_Caption without a contend.
So ony the first file have the right contend, all other files ar generatet with new names but all without contend.
What od i wrong?
Best regard,
Berni

Hi,
here i´m again.
I have found an other user with the same problem: viewtopic.php?f=178&t=71746&hilit=FAT32+empty
but with the STM Hardware.
They highre the Allocation Unit Size i formatt the card they higher the correct (not empty) files i can save.
I think i use the current lib version. How can i see the installed version?
BR,
