Detailed Description

The EEPROM API defines a common interface for EEPROM access on Contiki platforms.

A platform with EEPROM support must implement this API.

void eeprom_read	(	eeprom_addr_t	addr,
		unsigned char *	buf,
		int	size
	)

Read data from the EEPROM.

This function reads a number of bytes from the specified address in EEPROM and into a buffer in memory.

Parameters

addr	The address in EEPROM from which the data should be read.
buf	A pointer to the buffer to which the data should be stored.
size	The number of bytes to read.

Read data from the EEPROM.

Parameters

addr	The eeprom memory address
buf	It is the destination buffer in witch the bytes will be written
size	It is the number of byte to read

Write a buffer into EEPROM.

This function writes a buffer of the specified size into EEPROM.

Parameters

addr	The address in EEPROM to which the buffer should be written.
buf	A pointer to the buffer from which data is to be read.
size	The number of bytes to write into EEPROM.

Write a buffer into EEPROM.

Parameters

addr	The eeprom memory address
buf	It is the buffer of bytes that will be written to the eeprom
size	It is the number of byte to write
