Detailed Description

Functions to handle on board Eeprom data storage.

Function Documentation

eeprom_read()

int eeprom_read	(	uint16_t	address,
		uint8_t *	dst,
		uint16_t	size,
		uint8_t	crc_mode )

Reads n bytes from the given address.

Parameters

address	- address to read from.
dst	- pointer to the buffer where to put the data being read.
size	- number of bytes to be read.
crc_mode	- specify DONT_USE_CRC if no CRC check is needed, ONLY_CHECK_CRC to only check the CRC or LOAD_CHECK_CRC to check CRC and read the data into the specified buffer.

Returns

EE_ERROR if an error occured, EE_OK otherwise.

eeprom_type_identify()

void eeprom_type_identify

(

void

)

Identifies the on-board eeprom type.

The result is stored in the eeprom_type bitfield variable, using the eeprom identification bitmasks

eeprom_write()

int eeprom_write	(	uint16_t	address,
		const uint8_t *	src,
		uint16_t	size,
		uint8_t	crc_mode )

Writes n bytes at the given address.

Parameters

address	- address to write to.
src	- pointer to the data to be written.
size	- number of bytes to be written.
crc_mode	- specify DONT_USE_CRC or USE_CRC.

Returns

EE_ERROR if an error occured, EE_OK otherwise.
