Abstract: In recent years, with the rapid development of science and technology, SCM applications are continually deepening. This paper describes a microcontroller-based design of digital electronic stopwatch, the main features of this design is the timing accuracy of 0.001s, Jiejue traditional the result of a lack precision because of timing error and inequity, is essential facilities Gezhong one sports competition; Also set the View button hardware can be the last time on the stopwatch to save time for user queries
Keywords: SCM; digital electronic stopwatch; debug
