Abstract:Electronic ordering device, the key is 24 C1024 and AT89C51 two
chips, which 24C1024 used to store all the food's information, through the
AT89C51, the information will be transmitted to the LCD menu. However, they
need customers to choose good dishes, the menu will be automatically stored
in the AT89C51, and then can be directly connected to the computer through
the serial port will be transferred to the database menu, store, and display
and print it out. The AT89S52 is mainly used to control 24 C1024 and data
transfer between the liquid crystal, liquid crystal display part and the serial
communication part. Is the core of block board. He was fired through the C
language program into the.
