Abstract
With a wide range of SCM applications in various fields, many with a
sinle chip timing for the control of the game scoring device have emerged,
such as liquid crystal display LCD with MCU control the timing of
scoring device, LED seven segment display with MCU timing control
points and more.
This design based on the basic rules of basketball, the game of
basketball can achieve real-time control, total points and timing can be
solved in the game of basketball. The device includes hardware design
and software programming, mainly based on AT89C51 MCU as the core
components, and programmed to control the LED segment digital tube for
the display of the game time scoring ， Part time using CD4511 (seven
segment BCD decoder) for hardware decoding; scoring part is CD4094
(8-bit shift register storage bus) serial port expansion, monitor port, and
use 74LS21 (Dual four-input AND gate) to achieve the score of the
refresh function. Buzzer to sound the alarm part of the device used. The
system is set up with the schedule from time to time, schedule time to
pause, refresh in time A, B, and after the two sides achieved a temporary
