/***********************************************************
Author: Bernard Borredon
+Date : 21 decembre 2015
+Version: 1.3
+ - Correct write(uint32_t address, int8_t data[], uint32_t length) for eeprom >= T24C32.
+ Tested with 24C02, 24C08, 24C16, 24C64, 24C256, 24C512, 24C1025 on LPC1768 (mbed online and µVision V5.16a).
+ - Correct main test.
+
Date : 12 decembre 2013
Version: 1.2
- Update api documentation
