【 摘 要 】

This paper describes the design method of electronic clock based on STM32. The hardware circuit is designed, which uses the built-in RTC module of the STM32, and the backup battery is used to supply power. When first programming, the current date and time is wrote, after that the RTC module will automatically count. It also can be used to set the alarm time. Software programming can read the current time and conversion it, then it will be displayed on the LCD screen. The test results show that the design has the advantages of accurate timing, high reliability and long service life.
