EEPROM
get()
Description
Read any data type or object from the EEPROM.
Syntax
EEPROM.get(address, data)
Parameters
address: the location to read from, starting from 0 (int)
data: the data to read, can be a primitive type (eg. float) or a custom struct
Returns
A reference to the data passed in
Example
#include <EEPROM.h>
struct MyObject{
float field1;
byte field2;
char name[
10
]
;
}
;
void
setup
(
)
{
float f =
0.00f
; //Variable to store data read from EEPROM.
int eeAddress =
0
;
//EEPROM address to start reading from
Serial.begin
(
9600
)
;
while
(
!
Serial
)
{
;
// wait for serial port to connect. Needed for Leonardo only
}
Serial.print
(
"Read float from EEPROM: "
)
;
//Get the float data from the EEPROM at position 'eeAddress'
EEPROM.get
( eeAddress, f )
;
Serial.println
( f,
3
)
; //This may print 'ovf, nan' if the data inside the EEPROM is not a valid float.
// get() can be used with custom structures too.
eeAddress = sizeof(
float
)
;
//Move address to the next byte after float 'f'.
MyObject customVar;
//Variable to store custom object read from EEPROM.
EEPROM.get
( eeAddress, customVar )
;
Serial.println
(
"Read custom object from EEPROM: "
)
;
Serial.println
( customVar.field1
)
;
Serial.println
( customVar.field2
)
;
Serial.println
( customVar.name
)
;
}
void
loop
(

{
/* Empty loop */
}
