Warning: This beta is for testing with Particle IoT mesh devices.

Rename this folder SdFat and place it in the standard place for libraries.

I tested with a particle CLI project with a SdFat in a lib

Changess Version 1.0.10:

Added custom Particle driver to use DMA and allow use of SPI1.

To use SPI1 declare SdFat/SdFatEX class like this:

SdFat sd1(&SPI1);
// or
SdFatEX sd1(&SPI1);

Changed STM32 use of SPI ports. See STM32Test example.

To use second SPI port:

// Use second SPI port
SPIClass SPI_2(2);
SdFat sd2(&SPI_2);

Changes Version 1.0.9:

This version of SdFat has been modified to use standard POSIX/Linux definitions of open flags from fcntl.h.

Open flags are access modes, O_RDONLY, O_RDWR, O_WRONLY, and modifiers O_APPEND, O_CREAT, O_EXCL, O_SYNC, O_TRUNC.

The mods required changing the type for open flags from uint8_t to int so bugs are likely if any uint8_t local variables were missed.
