Digital clock design There are many ways , for example , can be posed of small and medium scale integrated circuits electronic bell 。 chip can also be used to implement electronic bell and so on. These methods have their own characteristics , including the use of electronic clock with MCU programming flexibility , functionality and ease of expansion. But here in order to learn digital circuits, including binational logic circuits and sequential circuits of study, using small and medium scale integrated circuits digital clock . Therefore, the system uses the MCU as the core controller digital clock , clock chip to read the values displayed by the display , and can be performed through the key signal to the microcontroller circuit to achieve normal display, clock and stopwatch calibration switch . Using AT89S52 microcontroller as the master clock module selection as the DS1302 clock chip, display module selection LCD1602, setting part of the selection key circuit . This design is a microcontroller as the core , the additional necessary peripheral circuits , through the preparation of the C language will be stored in the DS1302 chip year, month, day, hour, minute, second, through the serial input to the internal microcontroller , its number system conversion apparent on the DS1602 .
