+/******************************************************************************
+This will test an I2C EEPROM connected to mbed by writing a predefined byte at
+address 0 and then reading it back and comparing it with the known byte value a
+number of times. This test was written specifically for reproducing the bug
+reported here:
+
+https://mbed.org/forum/bugs-suggestions/topic/4128/
+
+Test configuration:
+
+* set 'ntests' to the number of iterations
+* set 'i2c_speed_hz' to the desired speed of the I2C interface
+* set 'i2c_delay_us' to the delay that will be inserted between 'write' and
+'read' I2C operations (https://mbed.org/users/mbed_official/code/mbed/issues/1
+for more details). '0' disables the delay.
+* define I2C_EEPROM_VERBOSE to get verbose output
+
+The test ran with a 24LC256 external EEPROM memory, but any I2C EEPROM memory
+that uses two byte addresses should work.
