The SD library allows for reading from and writing to SD cards, e.g. on the Arduino Ethernet Shield. It is built on sdfatlib by William Greiman. The library supports FAT16 and FAT32 file systems on standard SD cards and SDHC cards. It uses short 8.3 names for files.

This guide collects compatible hardware and great code examples that you can use if you want to get started with Secure Digital (SD) cards. The examples in this guide comes from the SD Library, which originally is based on SdFat by William Greiman.
SD - begin() Initializes the SD library and card. This begins use of the SPI bus (digital pins 11, 12, and 13 on most Arduino boards; 50, 51, and 52 on the Mega) and the chip select pin, which defaults to the hardware SS pin (pin 10 on most Arduino boards, 53 on the Mega).
15 lip 2024 · SD. Enables reading and writing on SD cards. Once an SD memory card is connected to the SPI interface of the Arduino board you can create files and read/write on them. You can also move through directories on the SD card.
Read from the file. read () inherits from the Stream utility class. Syntax. file.read() file.read(buf, len) Parameters. file: an instance of the File class (returned by SD.open ()). buf: an array of characters or bytes. len: the number of elements in buf.
