Hi all,

I am using LPC1769 REV C.
I have taken the I2C example code, but it is not working.
I am following the procedure given in periph_i2c/example/readme.text file provided in the example source code.
I am using lpcopen.
I have connected AT34C02 EEPROM.
After following the steps given in readme.txt, I am not able to read or write any data.
Even after writing data to device with address 0x5A, it is showing as:
Written 0 bytes of data to slave 0x5A.
If read:
Read 0 bytes of data from slave 0x5A.
Is the EEPROM inbuilt or which one should I use?
