This can be the hardware SS pin - pin 10 (on most Arduino boards) or pin 53 (on the Mega) - or another pin specified in the call to SD.begin(). Additionally, another pin must be used to select the SD card. The communication between the microcontroller and the SD card uses SPI, which takes place on digital pins 11, 12, and 13 (on most Arduino boards) or 50, 51, and 52 (Arduino Mega). As of version 1.0, the library supports opening multiple files. "/file.txt" is equivalent to "file.txt"). Because the working directory is always the root of the SD card, a name refers to the same file whether or not it includes a leading slash (e.g. The file names passed to the SD library functions can include paths separated by forward-slashes, /, e.g. The library supports FAT16 and FAT32 file systems on standard SD cards and SDHC cards. It is built on sdfatlib by William Greiman. The SD library allows for reading from and writing to SD cards, e.g. Reference Language | Libraries | Comparison | Changes ![]()
