Large, complex calculation ability is not up to the brain, and relatively easy to get wrong. Calculator as a fast general-purpose computing tools make it easy to use for the user. Calculator is one of Peoples Daily are very familiar with electronic products, at the same time, temperature and time are two elements in peoples lives. This design is to analyze emphatically the calculator software and hardware development process in the link and steps, attached two functions, namely, time and temperature, for the life of people brought convenient. The design system by the clock/calendar circuit, LCD display circuit, button adjust circuit and temperature detection circuit four parts. Concrete implementation on the hardware system platform USES the microcontroller STC89C52, LCD display LCD1602, clock chip DS1302 and temperature sensor DS18B20 and keyboard, form a multi-function calculator system. 52 series microcontroller technology is mature, powerful, wide application. Using single chip microcomputer as control core, can simplify the hardware circuit, single-chip microcomputer using software programming control can realize t
