ABSTRACT
As modern society increasingly rapid pace of working life, time for people to have more and more important in people's daily life and various social activities, can not do without time, time and people's daily life. Multi-function digital clock on the provision of a convenient, not only can accurately display the time, there is alarm settings, temperature measurement, etc. Other features, compared with the mechanical clock is more accurate and intuitive, is used digital circuit technology, the minute and second timing device, because no mechanical device, and therefore have a longer life, it has been widely used.
SCM is a set of CPU, RAM, ROM, I / O interfaces and interrupt system part in one of the devices, only external power supply and the crystal can be realized on digital information processing and control. SCM combined with multi-function digital clock, for the time display, temperature measurement is not only easy to control, simple configuration and flexibility of big advantages, but also greatly enhance the value of the technical indicators are detected, which can greatly enhance the quality of the product and quantity. Therefore, the MCU in modern life and more and more widely applied in industry.
Key words：Single-chip Microcomputer, Temperature Sensor, Clock
