I think I got in a bit over my head but I am sure this is not uncharted territory. 3 form, or a maximum of 12 characters (not counting the null character that terminates the string, which would make it 13 characters). read () example code. I have attempted to restrict the SD card from allowing these types of files onto the SD card in the first Assuming the SD chip select pin is: 10 Edit SD_CHIP_SELECT to change the SD chip select pin. So the file size stored in the FAT will always be the same while the file is open. 3 filenames and do not accept spaces. At the setup() the code that works: Dear all, I'm connecting my Arduino to an Adafruit SD Card Breakout Board. 241 // May need to reverse subscript order if porting elsewhere. I've noticed that under some conditions the sd card may become unaccessable and require the card to be removed and reinserted or the arduino cold booted with the card in it to regain access to the sd card. Did some researching and came across this site explaining that it is better and faster to store it in . It is the same for Micro SD card modules.
