SCM has many advantages, such as small size, light weight, antiinterference ability, less demanding on the environment, low cost, high reliability, good flexibility, developing more easily and so on. Now, it has bee the preferred model in measurement control system and a key ponent of new electronic products. Many time scoring matches using SCM has also e into being, such as the timer with liquid crystal display (LCD), the timer with LED sevensegment display ,etc. Time basketball scoring device as the core of SCM includes the timer, scoring devices, integrated controller and other ponents. This system is used of the modular design, in which the main display module is divided into time display module, scoring display module, timing alarm module, and key control keyboard module. Program structure of each module is simple and clear. So it is easy to write, debug and modify. Because the program is readable, part of program can be modified and other parts may remain unchanged. After programming, firstly we can use
