Examples
Connect to the following program with the terminal window set to 9600 baud. This next example will
write to the fi rst 10 locations of a 24LC512 using word sized addressing. Address is set as a word
sized variable. For the Address data we use a high and low byte modifi er to load the address values
from Address. For each loop we add 7 to databyte which is what we are writing to the EEPROM.
The values written are 0, 7, 14, 21, 28, 35, 42, 49, 56 and 63. The program will print to the terminal
window what it is writing and then what is being read. If the values above are not returned then you
have a bad EEPROM or you don’t have something wired correctly (see schematic for I2COUT).
