| fmanzano_dtk | 1:9e821e640117 | 15 | - Change address parameter size form uint16_t to uint32_t (error for eeprom > 24C256). |
| fmanzano_dtk | 1:9e821e640117 | 16 | - Change size parameter size from uint16_t to uint32_t (error for eeprom > 24C256). |
| fmanzano_dtk | 1:9e821e640117 | 17 | - Add EEPROM name as a private static const char array. |
| fmanzano_dtk | 1:9e821e640117 | 18 | - Add function getName. |
| fmanzano_dtk | 1:9e821e640117 | 19 | - Add a test program. |
