This design is based on STC12C5A60S2 MCU calendar design.On account of the fast pace of modern social life, people's awareness of time is more and more strong, in order to facilitate people quickly access to time information, we put forward a product scheme which can clearly display the year, month, minute and second . Optimize the interaction design between users and products, so that users feel convenient and fast. The design of this work mainly interacts with users through IIC display screen, which is divided into five functions, such as time and date display, temperature display and warning, time storage, alarm clock setting and focus mode. Users can control the system by pressing buttons and set the function mode they want. The data reading of the first four interactive interfaces is realized by the external chip, while the time reading of the focused mode is achieved by the internal clock of the single chip microcomputer. After testing, the data can be correctly displayed in the interface of time and date; Accurate temperature reading can achieve the ideal effect; Time storage and alarm Settings can be obtained from the memory chip storage data; Focus mode can be properly timed with the internal clock.
