ARDUINO-EEPROM-LIVING-AGE-EXTENSION

EEPROM Living Age Extension for Arduino - ATmega

Introduction

Instead for using external EPROM IC you can use this library.

EEPROMLivingAgeExtension is a library that allows your project to use the internal EEPROM to save data over the allocated address space, you define. The library is moving the data in this EEPROM address space. When it’s hits the 100,000 cycles limited for the cells it’s start to move the data to a new location in EEPROM. Starts from the beginning and works up to the end of the address space you assign. The life extension for your EEPROM is depended of how large the address space and how much data space you allocate. The data is stored in a Array[] and the Data and Address type in the library is of type Long (4-bits) or Data of type Int(2-bits) if you use the Interer version. You define the size of the data array: DATAWITHINEEPROM[0-1023] . And the size of DATASIZEWITHINEEPROM = DATAWITHINEEPROM.

Data library: Long

  • EEPROMLivingAgeExtension.zip

Data library: Integer

  • EEPROMLivingAgeExtensionInt.zip

EEPROM Life calculation for the allocated address space

Use this to calculate the optimized address space to your data and needed EEPROM life...

Start address: EEPROMADRESS = 0
End address:   EEPROMADRESS_LAST = 100

DataSpace = 4 + ( DATASIZEWITHINEEPROM * "4 or 2" )     ==>>   DATA-SIZE-WITHIN-EEPROM is value of 0-1023
                                                        ==>>   4 -> Long.  or 2 -> Integer library.

LIFECOUNTDOWN = ( ( EEPROMADRESS_LAST – EEPROMADRESS ) / DataSpace )  *  100.000

Using EEPROMLivingAgeExtension

The library has these three simple functions:

Data library: Long

EEPROM-LIVING-AGE-WRITE

EEPROMLivingAgeExtension.EEPROMLIVINGAGEWRITE( EEPROMADRESS, EEPROMADRESS_LAST, DATASIZEWITHINEEPROM, DATAWITHINEEPROM )

EEPROM-LIVING-AGE-READ

EEPROMLivingAgeExtension.EEPROMLIVINGAGEREAD( EEPROMADRESS, EEPROMADRESS_LAST, DATASIZEWITHINEEPROM, DATAWITHINEEPROM )

EEPROM-LIVING-AGE-LIFE-COUNTDOWN

EEPROMLivingAgeExtension.EEPROMLIVINGAGELIFECOUNTDOWN( EEPROMADRESS, EEPROMADRESS_LAST, DATASIZEWITHINEEPROM, LIFECOUNTDOWN

Data library: Integer

EEPROM-LIVING-AGE-INT-WRITE

EEPROMLivingAgeExtensionInt.EEPROMLIVINGAGEINTWRITE( EEPROMADRESS, EEPROMADRESS_LAST, DATASIZEWITHINEEPROM, DATAWITHINEEPROM )

EEPROM-LIVING-AGE-INT-READ

EEPROMLivingAgeExtensionInt.EEPROMLIVINGAGEINTREAD( EEPROMADRESS, EEPROMADRESS_LAST, DATASIZEWITHINEEPROM, DATAWITHINEEPROM )

EEPROM-LIVING-AGE-INT-LIFE-COUNTDOWN

EEPROMLivingAgeExtensionInt.EEPROMLIVINGAGEINTLIFECOUNTDOWN( EEPROMADRESS, EEPROMADRESS_LAST, DATASIZEWITHINEEPROM, LIFECOUNTDOWN )

Demostration - Long library.

Here is an example to demonstrate how the EEPROMLivingAgeExtension works:

EEPROMADRESS = 0;             // Start addresses for the data. 0 -> 1023.
EEPROMADRESS_LAST = 1023;     // End addresses for data.       0 -> 1023.

DATAWITHINEEPROM[10];         // Size of Data Arrays[]...      0 -> 1023. (Datatype Long or Integer => Library)

DATASIZEWITHINEEPROM = 10;    // Number of Data in the Array[]...  0 -> 1023.

LIFECOUNTDOWN = 0;            // Return the remaining number of Life, for the EEPROM cells!.. MAX = 12.800.000
