Abstract:
SCM is the main computer components are integrated in a chip on the micro-computer. It is a multi-count and interface in one of microcontrollers, are widely used in smart products and industrial automation, and 52 in the MCU MCU is a most typical and most representative of a kind.
The graduation project's main task is to design a basketball game Scoreboard, including real-designed hardware circuits and software design. Hardware-design really is the main task: LED digital indicators, key control system design and support functions of the design points. Software design, including: various members of the information column shows (including members of fouls, personal scores), total, total historical records show that extra points and display modules through the serial port and interrupt the communication of data between computers To achieve. This paper presents the MCU Basketball Scoreboard of the entire design process, using C-language programming. The topic chosen as the core AT89C52 control components, designed to use the day-to-day competitions in basketball Scoreboard. 74 LS595 design at the same time quoted string and conversion chips, to resolve a number of LED digital display at the same time the issue of hardware compact and low cost. The SCM Basketball Scoreboard can be adapted to the game of basketball in addition to other than any two teams to participate in sports competitions, through the keys to amend each set. Operation reliable, convenient and practical, have a certain value and competitive value.
Key words: AT89C52 SCM, LED digital control, 74 LS595 chips, C language, Basketball Scoreboard
