| bborredon | 2:79ed7ff7c23d | 7 | Version: 1.2 |
| bborredon | 2:79ed7ff7c23d | 8 | - Update api documentation |
| bborredon | 2:79ed7ff7c23d | 9 | |
| bborredon | 1:a262173cac81 | 10 | Date: 11 december 2013 |
| bborredon | 1:a262173cac81 | 11 | Version: 1.1 |
| bborredon | 1:a262173cac81 | 12 | - Change address parameter size form uint16_t to uint32_t (error for eeprom > 24C256). |
| bborredon | 1:a262173cac81 | 13 | - Change size parameter size from uint16_t to uint32_t (error for eeprom > 24C256). |
| bborredon | 1:a262173cac81 | 14 | - Add EEPROM name as a private static const char array. |
| bborredon | 1:a262173cac81 | 15 | - Add function getName. |
| bborredon | 1:a262173cac81 | 16 | - Add a test program. |
