Library Read Me

This content is provided by the library maintainer and has not been validated or approved. The Arduino SdFatAsync library provides read/write access to FAT16/FAT32 file systems on SD/SDHC flash cards, with async read capability.

SdFat requires Arduino 1.6x or greater.

Key changes:

FatFile::read returns a future, which can be polled if the SPI/SD/SDHC transfer happens in the background.

Support for multiple SPI ports now uses a pointer to a SPIClass object.

See the STM32Test example.

explicit SdFat(SPIClass* spiPort);
\\ or
explicit SdFatEX(SPIClass* spiPort);

Open flags now follow POSIX conventions. O_RDONLY is the same as O_READ and O_WRONLY is the same as O_WRITE. One and only one of of the mode flags, O_RDONLY, O_RDWR, or O_WRONLY is required.

Open flags for Particle Gen3 and ARM boards are now defined by fcntl.h. See SdFatConfig.h for options.

Support for particle Gen3 devices.

New cluster allocation algorithm.
