I having 2 problems:
1) The documented sketch fails to open the created .csv file. It creates the file, but it looks like it can't open it. If I change the file type to .txt everything works fine, and I no longer get the "couldn't create file" error.
2) When the file is created, it's created / modification date is set to something like 01-01-2010. How do I get the modify date set?
This version does not work:
Code: Select all
// create a new file
char filename[] = "LOGGER00.CSV";
for (uint8_t i = 0; i < 100; i++) {
filename[6] = i/10 + '0';
filename[7] = i%10 + '0';
if (! SD.exists(filename)) {
// only open a new file if it doesn't exist
logfile = SD.open(filename, FILE_WRITE);
break; // leave the loop!
}
}
if (! logfile) {
error("couldnt create file");
}Code: Select all
// create a new file
char filename[] = "LOGGER00.TXT";
for (uint8_t i = 0; i < 100; i++) {
filename[6] = i/10 + '0';
filename[7] = i%10 + '0';
if (! SD.exists(filename)) {
// only open a new file if it doesn't exist
logfile = SD.open(filename, FILE_WRITE);
break; // leave the loop!
}
}
if (! logfile) {
error("couldnt create file");
}
