Function Documentation

int eeprom_get_byte	(	unsigned int	addr,
		unsigned char *	byte
	)

reads a byte from eeprom

Pass it thge address and a pointer to a byte where the byte at the address will be stored

Returns:

0 if successful (byte is set to the eeprom value at addr), nonzero if there was a problem

int eeprom_put_byte	(	unsigned int	addr,
		unsigned char	byte
	)

store a byte to eeproem

Returns:

0 if success, nonzero on failure

unsigned char get_bom_type

(

void

)

get stored robot ID

checks that EEPROM has been programed with an BOM type and returns it

Returns:

the robot bom type as defined in bom.h, if it is stored. If it returns 0xFF it is probably invalid

unsigned char get_robotid

(

void

)

get stored robot ID

checks that EEPROM has been programed with an ID and returns it

Returns:

the robot id, if it is stored. If it returns 0xFF it is probably invalid
