Function Documentation

ERROR_CODES CARME_EEPROM_Read	(	uint8_t *	recdata,
		uint8_t	nbrOfChar,
		uint8_t	startAddress
	)

Read an Array of char to the Eeprom.

Parameters

[out]	recdata	data to read
[in]	nbrOfChar	number of bytes to read from the EEPROM
[in]	startAddress	Startaddress to read from Range (0x0000 - 0x07FF)

Returns

ERROR_CODES

• CARME_NO_ERROR
• CARME_ERROR_EEPROM_OVERFLOW
• CARME_ERROR_EEPROM_BUSY

Definition at line 175 of file eeprom.c.
