| Abstract: | Keyboard is the most common input devices. It is widely used in microcomputer and a variety of terminal equipment. The computer operator inputs each kind of instruction and data to the computer through the keyboard, in order to command the computer to work. Therefore the keyboard design is good or bad, will be directly related to the reliability and stability of the system. In this paper, using the keyboard control chip BC7281 and AT89S52 chip input / output interface to design a keyboard with the function keys. |
