# Arduino External EEPROM Library v3.4 #
Original library by http://github.com/JChristensen/extEEPROM
## Introduction ##
**Arduino External EEPROM Library**
This library will work with most I2C serial EEPROM chips between 2k bits and 2048k bits (2M bits) in size. Multiple EEPROMs on the bus are supported as a single address space. I/O across block, page and device boundaries is supported. Certain assumptions are made regarding the EEPROM device addressing. These assumptions should be true for most EEPROMs but there are exceptions, so read the datasheet and know your hardware.
The library should also work for EEPROMs smaller than 2k bits, assuming that there is only one EEPROM on the bus and also that the user is careful to not exceed the maximum address for the EEPROM.
The **extEEPROM Library** has been tested with:
- Microchip 24AA02E48 (2k bit)
- 24xx32 (32k bit, thanks to Richard M)
- Microchip 24LC256 (256k bit)
- Microchip 24FC1026 (1M bit, thanks to Gabriele B on the Arduino forum)
- ST Micro M24M02 (2M bit)
- Atmel AT24C256C (32k x 8, thanks to Searobin)
The **extEEPROM Library** will **NOT** work with Microchip 24xx1025 as its control byte does not conform to the following assumptions.
**Device addressing assumptions:**
- The I2C address sequence consists of a control byte followed by one address byte (for EEPROMs <= 16k bits) or two address bytes (for EEPROMs > 16k bits).
- The three least-significant bits in the control byte (excluding the R/W bit) comprise the three most-significant bits for the entire address space, i.e. all chips on the bus. As such, these may be chip-select bits or block-select bits (for individual chips that have an internal block organization), or a combination of both (in which case the block-select bits must be of lesser significance than the chip-select bits).
- Regardless of the number of bits needed to address the entire address space, the three most-significant bits always go in the control byte. Depending on EEPROM device size, this may result in one or more of the most significant bits in the I2C address bytes being unused (or "don't care" bits).
- An EEPROM contains an integral number of pages.
Note that the Arduino Wire library has a buffer size of 32 bytes. This limits the size of physical I/Os that can be done to EEPROM. For writes, one or two bytes are used for the address, so writing is therefore limited to 31 or 30 bytes. Because the **extEEPROM Library** will handle I/O across block, page and device boundaries, the only consequence this has for the user is one of efficiency; arbitrarily large blocks of data can be written and read; however, carefully chosen block sizes may reduce the number of physical I/Os needed.
## Installation ##
### Install with the Library Manager
- For Arduino IDE versions 1.6.2 and up, add library by selecting "Manage Libraries..." from the "Include Library" submenu within the Sketch menu.
- The library manager will open and you will find a list of libraries that are already installed or ready for installation. Scroll the list to find **extEEPROM** library and click on it.
- Select the version of the library you want to install.
- Click on install and wait for the IDE to install the new library. Downloading may take time depending on your connection speed.
- Once it has finished, an Installed tag should appear, You can close the library manager.
### Manual Install
- Go to http://github.com/PaoloP74/extEEPROM, click the **Download ZIP** button and save the ZIP file to a convenient location on your PC.
- Uncompress the downloaded file. This will result in a folder containing all the files for the library, that has a name that includes the branch name, usually **extEEPROM-master**.
- Rename the folder to just **extEEPROM**.
- Copy the renamed folder to the Arduino sketchbook\libraries folder.
## Examples ##
The following example sketch is included with the **extEEPROM Library**:
- **eepromReadWrite**
- **eepromTest:** Writes 32-bit integers to the entire EEPROM address space, starting at address 0 and continuing to the topmost address. These are then read back in and verified; any discrepancies are reported to the serial monitor.
- **eepromTest_Wire1**
## Usage notes ##
The **extEEPROM Library** is designed for use with Arduino version 1.0 or later.
To use the **extEEPROM Library**, the standard [Arduino Wire library](http://arduino.cc/en/Reference/Wire) must also be included. For brevity, this include is not repeated in the examples below:
```c++
#include <Wire.h> //http://arduino.cc/en/Reference/Wire (included with Arduino IDE)
```
## Enumerations ##
### eeprom_size_t
##### Description
EEPROM device size in k-bits. Many manufacturers' EEPROM part numbers are designated in k-bits.
##### Values
- kbits_2
- kbits_4
- kbits_8
- kbits_16
- kbits_32
- kbits_64
- kbits_128
- kbits_256
- kbits_512
- kbits_1024
- kbits_2048
### twiClockFreq_t
##### Description
I2C bus speed.
##### Values
- extEEPROM::twiClock100kHz
- extEEPROM::twiClock400kHz
## Constructor ##
### extEEPROM(eeprom_size_t devCap, byte nDev, unsigned int pgSize, byte busAddr)
##### Description
Instantiates an external EEPROM object.
##### Syntax
`extEEPROM myEEPROM(eeprom_size_t devCap, byte nDev, unsigned int pgSize, byte busAddr);`
##### Parameters
**devCap** *(eeprom_size_t)*: The size of one EEPROM device in k-bits. Choose a value from the eeprom_size_t enumeration above.
**nDev** *(byte)*: The number of EEPROM devices on the bus. Note that if there are multiple EEPROM devices on the bus, they must be identical and each must have its address pins strapped properly.
**pgSize** *(unsigned int)*: The EEPROM page size in bytes. Consult the datasheet if you are unsure of the page size.
**busAddr** *(byte)*: The base I2C bus address for the EEPROM(s). 0x50 is a common value and this parameter can be omitted, in which case 0x50 will be used as the default.
##### Example
```c++
extEEPROM myEEPROM(kbits_256, 2, 64); //two 24LC256 EEPROMS on the bus
extEEPROM oddEEPROM(kbits_8, 1, 16, 0x42); //an EEPROM with a non-standard I2C address
```
## Methods ##
### begin(twiClockFreq_t freq, TwoWire *_comm)
##### Description
Initializes the library. Call this method once in the setup code. begin() does a dummy I/O so that the user may interrogate the return status to ensure the EEPROM is operational.
##### Syntax
`myEEPROM.begin(twiClockFreq_t freq);`
or
`myEEPROM.begin(twiClockFreq_t freq, TwoWire *_comm);`
##### Parameters
**freq** *(twiClockFreq_t)*: The desired I2C bus speed, `extEEPROM::twiClock100kHz` or `extEEPROM::twiClock400kHz`. Can be omitted in which case it will default to `twiClock100kHz`.
**NOTE:** When using 400kHz, if there are other devices on the bus they must all support a 400kHz bus speed. **Secondly**, the other devices should be initialized first, as other libraries may not support adjusting the bus speed. To ensure the desired speed is set, call the extEEPROM.begin() function *after* initializing all other I2C devices.
**_comm** *(TwoWire * )*: The Used I2C TwoWire channel . Can be omitted in which case it will default to the first Arduino I2C channel `Wire`. If another of the possible I2C channel is used its pointer shall be passed as parameter.
**NOTE:** If another I2C channel is unse, and not the default one, the first parameters **freq** MUST be defined.
##### Returns
I2C I/O status, zero if successful *(byte)*. See the [Arduino Wire.endTransmission() function](http://arduino.cc/en/Reference/WireEndTransmission) for a description of other return codes.
##### Examples
```c++
extEEPROM myEEPROM(kbits_256, 2, 64);
byte i2cStat = myEEPROM.begin(extEEPROM::twiClock400kHz);
if ( i2cStat != 0 ) {
//there was a problem
}
```
##### Use of other I2C channel
```c++
extEEPROM myEEPROM(kbits_256, 2, 64);
byte i2cStat = myEEPROM.begin(extEEPROM::twiClock400kHz, &Wire1);
if ( i2cStat != 0 ) {
//there was a problem
}
```
### write(unsigned long addr, byte *values, unsigned int nBytes)
##### Description
Write one or more bytes to external EEPROM.
##### Syntax
`myEEPROM.write(unsigned long addr, byte* values, byte nBytes);`
##### Parameters
**addr** *(unsigned long)*: The beginning EEPROM location to write.
**values** _(byte*)_: Pointer to an array containing the data to write.
**nBytes** *(unsigned int)*: The number of bytes to write.
##### Returns
I2C I/O status, zero if successful *(byte)*. See the [Arduino Wire.endTransmission() function](http://arduino.cc/en/Reference/WireEndTransmission) for a description of other return codes. Returns a status of EEPROM_ADDR_ERR if the I/O would extend past the top of the EEPROM address space.
##### Example
```c++
byte myData[10];
//write 10 bytes starting at location 42
byte i2cStat = myEEPROM.write(42, &data, 10);
if ( i2cStat != 0 ) {
//there was a problem
if ( i2cStat == EEPROM_ADDR_ERR) {
//bad address
}
else {
//some other I2C error
}
}
```

/*-----------------------------------------------------------------------------*
* extEEPROM.cpp - Arduino library to support external I2C EEPROMs. *
* *
* This library will work with most I2C serial EEPROM chips between 2k bits *
* and 2048k bits (2M bits) in size. Multiple EEPROMs on the bus are supported *
* as a single address space. I/O across block, page and device boundaries *
* is supported. Certain assumptions are made regarding the EEPROM *
* device addressing. These assumptions should be true for most EEPROMs *
* but there are exceptions, so read the datasheet and know your hardware. *
* *
* The library should also work for EEPROMs smaller than 2k bits, assuming *
* that there is only one EEPROM on the bus and also that the user is careful *
* to not exceed the maximum address for the EEPROM. *
* *
* Library tested with: *
* Microchip 24AA02E48 (2k bit) *
* 24xx32 (32k bit, thanks to Richard M) *
* Microchip 24LC256 (256k bit) *
* Microchip 24FC1026 (1M bit, thanks to Gabriele B on the Arduino forum) *
* ST Micro M24M02 (2M bit) *
* *
* Library will NOT work with Microchip 24xx1025 as its control byte does not *
* conform to the following assumptions. *
* *
* Device addressing assumptions: *
* 1. The I2C address sequence consists of a control byte followed by one *
* address byte (for EEPROMs <= 16k bits) or two address bytes (for *
* EEPROMs > 16k bits). *
* 2. The three least-significant bits in the control byte (excluding the R/W *
* bit) comprise the three most-significant bits for the entire address *
* space, i.e. all chips on the bus. As such, these may be chip-select *
* bits or block-select bits (for individual chips that have an internal *
* block organization), or a combination of both (in which case the *
* block-select bits must be of lesser significance than the chip-select *
* bits). *
* 3. Regardless of the number of bits needed to address the entire address *
* space, the three most-significant bits always go in the control byte. *
* Depending on EEPROM device size, this may result in one or more of the *
* most significant bits in the I2C address bytes being unused (or "don't *
* care"). *
* 4. An EEPROM contains an integral number of pages. *
* *
* To use the extEEPROM library, the Arduino Wire library must also *
* be included. *
* *
* Jack Christensen 23Mar2013 v1 *
* 29Mar2013 v2 - Updated to span page boundaries (and therefore also *
* device boundaries, assuming an integral number of pages per device) *
* 08Jul2014 v3 - Generalized for 2kb - 2Mb EEPROMs. *
