uint32_t BSP_EEPROM_Init ( void )

Initializes peripherals used by the EEPROM device selected.

Return values:

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

Definition at line 145 of file stm32l476g_eval_eeprom.c.

References EEPROM_FAIL, and EEPROM_DrvTypeDef::Init.

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_SelectDevice ( uint8_t DeviceID )

Select the EEPROM device to communicate.

Parameters:

DeviceID,:

Specifies the EEPROM device to be selected. This parameter can be one of following parameters:

BSP_EEPROM_M24LR64
BSP_EEPROM_M24LR64_A01
BSP_EEPROM_M24128

Return values:

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

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 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
