Depedencies:

SparkFun_External_EEPROM.h // Click here to get the library: http://librarymanager/All#SparkFun_External_EEPROM (for External EEPROM's)

Tips:

• For proper work execute Wire.begin() function in setup() function (main sketch). (External EEPROM)

• When you finish your list is better to set Write Protect on your chip. (External EEPROM)

Example of create objects:

EPList<EEPROMClass,64> EC(4096); // Static allocation (Size of EEPROM)

EPList<EEPROMClass,64> *EC = new EPList<64>(4096); // Dynamic allocation (Size of EEPROM chip)

EPList<ExternalEEPROM,64> EC(0x50,32000); // Static allocation ExternalEEPROM (i2c chip Address, Size of EEPROM chip)

EPList<ExternalEEPROM,64> *EC = new EPList<64>(0x50,32000); // Dynamic allocation ExternalEEPROM (Address, Size of EEPROM chip)

First argument of template is type of used EEPROM (EEPROMClass / ExternalEEPROM) and second is size of one item on the list.

Example of use:

Example of add some items.

EC->pushItem("I'm inside the chip. "); EC->pushItem("Save your space. Thank you.");

Get some Strings from list on EEPROM in easy way

Serial.println(EC[0]); Serial.println((*EC)[0]);

Change some Strings from list on EEPROM in easy way

EC.setItem(0,"Good Job.")
