uint32_t BSP_EEPROM_Init

(

void

)

Initializes peripherals used by the I2C EEPROM driver.

Note:

There are 2 different versions of M24LR64 (A01 & A02). Then try to connect on 1st one (EEPROM_I2C_ADDRESS_A01) and if problem, check the 2nd one (EEPROM_I2C_ADDRESS_A02)

Return values:

EEPROM_OK

(0) if operation is correctly performed, else return value different from EEPROM_OK (0)

uint32_t BSP_EEPROM_ReadBuffer	(	uint8_t *	pBuffer,
		uint16_t	ReadAddr,
		uint32_t *	NumByteToRead
	)

Reads a block of data from the EEPROM device selected.

Parameters:

pBuffer	pointer to the buffer that receives the data read from the EEPROM.
ReadAddr	EEPROM's internal address to start reading from.
NumByteToRead	pointer to the variable holding number of bytes to be read from the EEPROM.

Note:

The variable pointed by NumByteToRead is reset to 0 when all the data are read from the EEPROM. Application should monitor this variable in order know when the transfer is complete.

Return values:

EEPROM_OK

(0) if operation is correctly performed, else return value different from EEPROM_OK (0) or the timeout user callback.

void BSP_EEPROM_TIMEOUT_UserCallback

(

void

)

Basic management of the timeout situation.

Return values:

None.

uint32_t BSP_EEPROM_WriteBuffer	(	uint8_t *	pBuffer,
		uint16_t	WriteAddr,
		uint32_t	NumByteToWrite
	)

Writes buffer of data to the EEPROM device selected.

Parameters:

pBuffer	pointer to the buffer containing the data to be written to the EEPROM.
WriteAddr	EEPROM's internal address to write to.
NumByteToWrite	number of bytes to write to the EEPROM.

Return values:

EEPROM_OK

(0) if operation is correctly performed, else return value different from EEPROM_OK (0) or the timeout user callback.

< If NumByteToWrite < EEPROM_PAGESIZE

< If NumByteToWrite < EEPROM_PAGESIZE

< If the number of data to be written is more than the remaining space in the current page:

< Write the data contained in same page

< Write the remaining data in the following page
