I haven't gone through the code, but keep in mind that the 
24c04 needs a few milliseconds to complete a write. To write 
a byte, you have to check if the previous write was successfull, 
by checking the acknowledge. If the 24c04 doesn't ACK, it is 
still busy writing. Keep on trying until it acknowledges the 
write command.
