Along with the highspeed development of the puter technology, Single Chip Microcosm with its special characteristics, Have already applied extensively and various intelligent instrument, Family electric apparatus, the electron toy etc. each realm. The design topic that therefore uses Single Chip Microcosm to carry out electric clock emerge with the tide of the times, the multifunction control capability ability that make use of Single Chip Microcosm is very the implementation request. The main Purpose of this topic is the design that uses Single Chip Microcosm to carry out the numerical electric clock. Make use of Single Chip Microcosm’s the characteristics of the machine, the product that passes to write procedure to control us carries out the function of[with] our demand. In the topic still have a task is our display module, In order to display the time we need 6 position digits, for the sake of the convenience, we display time with two four position integral whole tube, so how to pass the programming is also a point to the control figures tube display. The whole process is to design first and weld good hardware telephone, Be being the function that writes applied procedu
