Public Member Functions
	SPIFlash (uint8_t slaveSelectPin, uint16_t jedecID=0)
	Constructor.

bool	initialize ()
	setup SPI, read device ID etc...

void	command (uint8_t cmd, bool isWrite=false)
	Send a command to the flash chip, pass TRUE for isWrite when its a write command.

uint8_t	readStatus ()
	return the STATUS register

uint8_t	readByte (uint32_t addr)
	read 1 byte from flash memory

void	readBytes (uint32_t addr, void *buf, uint16_t len)
	read unlimited # of bytes

void	writeByte (uint32_t addr, uint8_t byt)
	Write 1 byte to flash memory.

void	writeBytes (uint32_t addr, const void *buf, uint16_t len)
	write multiple bytes to flash memory (up to 64K), if define SPIFLASH_SST25TYPE is set AAI Word Programming will be used

bool	busy ()
	check if the chip is busy erasing/writing

void	chipErase ()
	erase entire flash memory array

void	blockErase4K (uint32_t address)
	erase a 4Kbyte block

void	blockErase32K (uint32_t address)
	erase a 32Kbyte block

void	blockErase64K (uint32_t addr)
	erase a 64Kbyte block

uint16_t	readDeviceId ()
	Get the manufacturer and device ID bytes (as a short word)

uint8_t *	readUniqueId ()
	Get the 64 bit unique identifier, stores it in UNIQUEID[8].

void	sleep ()
	Put device to sleep.

void	wakeup ()
	Wake device.

void	end ()
	end

Static Public Attributes
static uint8_t	UNIQUEID [8]
	Storage for unique identifier.
