At present, with the rapid development of the MCU applications,the embedded systems as the core of microcontroller have been widely used in various fields. Based on SCM in timing measurement and control, I design a kind of basketball game timing and scoring system controlled by AT89S51.
This paper mainly describes the use of MCU timing and scoring system, from the beginning of the designing of software, hardware, discussed both proceed to the design, testing and other aspects. During the basketball games, in order to speed up the game’s rhythm, beside of the countdown of total time, it also needs attacker should be in the act of shooting in 24 seconds. Otherwise will be seen as violations. The basketball game Timing & Scoring can record the time of both the cumulative time and the possession of each team. This system is effective and practical , using button to operate, and eight digital to display. The function of button is in line with the requirements of the basketball games, including 24 seconds of attack time, the total time display, the score display of both teams. In addition the score and time can be modified.
