Description

EEPROM Interface.

Function Documentation

EEPROM_GetSize()

uint32_t EEPROM_GetSize

(

void

)

Get EEPROM memory size in bytes.

Returns

Memory size in bytes

The function returns the EEPROM size in bytes.

EEPROM_Initialize()

int32_t EEPROM_Initialize

(

void

)

Initialize EEPROM.

Returns

• 0: function succeeded
• -1: function failed

The function initializes the EEPROM memory. The function returns an integer value of 0 on success, and -1 on error.

EEPROM_ReadData()

int32_t EEPROM_ReadData	(	uint32_t	addr,
		uint8_t *	buf,
		uint32_t	len
	)

Read data from EEPROM.

Parameters

[in]	addr	EEPROM address
[in]	buf	Pointer where data will be read from EEPROM
[in]	len	Number of data bytes to read

Returns

• 0: function succeeded
• -1: function failed

The function reads data from an EEPROM memory. The parameter addr is the address of the EEPROM. The parameter buf is a pointer to the location that stores the data read form the EEPROM. The parameter len is the number of bytes to read. The function returns an integer value of 0 on success, and -1 on error.

EEPROM_Uninitialize()

int32_t EEPROM_Uninitialize

(

void

)

De-initialize EEPROM.

Returns

• 0: function succeeded
• -1: function failed

The function de-initializes the EEPROM memory. The function returns an integer value of 0 on success, and -1 on error.

EEPROM_WriteData()

int32_t EEPROM_WriteData	(	uint32_t	addr,
		const uint8_t *	buf,
		uint32_t	len
	)

Write data to EEPROM.

Parameters

[in]	addr	EEPROM address
[in]	buf	Pointer with data to write to EEPROM
[in]	len	Number of data bytes to write

Returns

• 0: function succeeded
• -1: function failed

The function writes data to EEPROM memory. The parameter addr is the address of the EEPROM. The parameter buf is a pointer to the data to be written to the EEPROM. The parameter len is the number of bytes to write. The function returns an integer value of 0 on success, and -1 on error.
