## **EEPROM Library V2.0** for Arduino
**Written by:** _Christopher Andrews_.
### **What is the EEPROM library.**
Th EEPROM library provides an easy to use interface to interact with the internal non-volatile storage found in AVR based Arduino boards. This library will work on many AVR devices like ATtiny and ATmega chips.
### **How to use it**
The EEPROM library is included in your IDE download. To add its functionality to your sketch you'll need to reference the library header file. You do this by adding an include directive to the top of your sketch.
```Arduino
#include <EEPROM.h>
void setup(){
}
void loop(){
}
```
The library provides a global variable named `EEPROM`, you use this variable to access the library functions. The methods provided in the EEPROM class are listed below.
You can view all the examples [here](examples/).
### **Library functions**
#### **`EEPROM.read( address )`** [[_example_]](examples/eeprom_read/eeprom_read.ino)
This function allows you to read a single byte of data from the eeprom.
Its only parameter is an `int` which should be set to the address you wish to read.
The function returns an `unsigned char` containing the value read.
#### **`EEPROM.write( address, value )`** [[_example_]](examples/eeprom_write/eeprom_write.ino)
The `write()` method allows you to write a single byte of data to the EEPROM.
Two parameters are needed. The first is an `int` containing the address that is to be written, and the second is a the data to be written (`unsigned char`).
This function does not return any value.
#### **`EEPROM.update( address, value )`** [[_example_]](examples/eeprom_update/eeprom_update.ino)
This function is similar to `EEPROM.write()` however this method will only write data if the cell contents pointed to by `address` is different to `value`. This method can help prevent unnecessary wear on the EEPROM cells.
This function does not return any value.
#### **`EEPROM.get( address, object )`** [[_example_]](examples/eeprom_get/eeprom_get.ino)
This function will retrieve any object from the EEPROM.
Two parameters are needed to call this function. The first is an `int` containing the address that is to be written, and the second is the object you would like to read.
This function returns a reference to the `object` passed in. It does not need to be used and is only returned for conveience.
#### **`EEPROM.put( address, object )`** [[_example_]](examples/eeprom_put/eeprom_put.ino)
This function will write any object to the EEPROM.
Two parameters are needed to call this function. The first is an `int` containing the address that is to be written, and the second is the object you would like to write.
This function uses the _update_ method to write its data, and therefore only rewrites changed cells.
This function returns a reference to the `object` passed in. It does not need to be used and is only returned for conveience.
#### **Subscript operator: `EEPROM[address]`** [[_example_]](examples/eeprom_crc/eeprom_crc.ino)
This operator allows using the identifier `EEPROM` like an array.
EEPROM cells can be read _and_ **_written_** directly using this method.
This operator returns a reference to the EEPROM cell.
```c++
unsigned char val;
//Read first EEPROM cell.
val = EEPROM[ 0 ];
//Write first EEPROM cell.
EEPROM[ 0 ] = val;
//Compare contents
if( val == EEPROM[ 0 ] ){
//Do something...
}
```
#### **`EEPROM.length()`**
This function returns an `unsigned int` containing the number of cells in the EEPROM.
---
### **Advanced features**
This library uses a component based approach to provide its functionality. This means you can also use these components to design a customized approach. Two background classes are available for use: `EERef` & `EEPtr`.
#### **`EERef` class**
This object references an EEPROM cell.
Its purpose is to mimic a typical byte of RAM, however its storage is the EEPROM.
This class has an overhead of two bytes, similar to storing a pointer to an EEPROM cell.
```C++
EERef ref = EEPROM[ 10 ]; //Create a reference to 11th cell.
ref = 4; //write to EEPROM cell.
unsigned char val = ref; //Read referenced cell.
```
#### **`EEPtr` class**
This object is a bidirectional pointer to EEPROM cells represented by `EERef` objects.
Just like a normal pointer type, this type can be dereferenced and repositioned using
increment/decrement operators.
```C++
EEPtr ptr = 10; //Create a pointer to 11th cell.
*ptr = 4; //dereference and write to EEPROM cell.
unsigned char val = *ptr; //dereference and read.
ptr++; //Move to next EEPROM cell.
```
#### **`EEPROM.begin()`**
This function returns an `EEPtr` pointing to the first cell in the EEPROM.
This is useful for STL objects, custom iteration and C++11 style ranged for loops.
#### **`EEPROM.end()`**
This function returns an `EEPtr` pointing at the location after the last EEPROM cell.
Used with `begin()` to provide custom iteration.
**Note:** The `EEPtr` returned is invalid as it is out of range. Infact the hardware causes wrapping of the address (overflow) and `EEPROM.end()` actually references the first EEPROM cell.

/***
eeprom_get example.
This shows how to use the EEPROM.get() method.
To pre-set the EEPROM data, run the example sketch eeprom_put.
This sketch will run without it, however, the values shown
will be shown from what ever is already on the EEPROM.
This may cause the serial object to print out a large string
of garbage if there is no null character inside one of the strings
loaded.

/*
EEPROM.h - EEPROM library for the Digistump DigiX
This is mostly the merger of the stock Arduino EEPROM library, original
Copyright (c) 2006 David A. Mellis/Christopher Andrews 2015 (LGPL 2.1) with a
few functions from Dennis Schweer (Inglorious Engineer)'s Extensive TWI/I2C
EEPROM Library for 24LCxxx devices v0.4.1 (CC-BY-SA), as distributed with the
DigiX core.
Merging work by SukkoPera <software@sukkology.net>, 2016.
The basic idea is to create a library that is interface-compatible with
Arduino's stock library that is used on non-Due boards, to achieve
compatibility at source level, so that the usual EEPROM.write()/read()/get()
/put() calls can be used.
I'm not really sure of what license the resulting code should be released
under, so I'm leaving the LGPL 2.1, as most of the code here actually came
under that license, and the rest is pretty basic stuff, but let me know if I
should change that.
