conceptual formulation
In this day and age, there are many small sports clubs and ambitious amateur athletes that want to compete and measure themselves with others in their preferred sports. To do that properly, they require a score display board.
Looking at todays market, we realize that there are only simple and inadequate score boards around compared to the extremely large and horrendously priced professional stadium boards. Our goal is to construct a mobile score display that can be used to keep the score for the majority of ball sports around.
details on execution
We constructed an upright independently standing triangle shaped board with two identical displays that enable the players, referees and audience to see the score from all angles (see illustration X).
To enable the referee easy input access, we created an external input board with a standard 9-pin D-sub cable that will be connected to mobile display board. We took special care in the development of the external input box to arrange the keys clearly so as to make it user friendly.
We used two different size 7-segment displays from the Kingbright company, each attached to a separate module to show the difference from the actual score and the set being played. The score will be displayed larger than the set display. In addition, we used the two smaller sized displays to show the playing time.
Most clubs are identified with a three lettered abbreviation (usually the first three letters of the clubs name) and we have incorporated this in a 3 dot matrix display for each club.
All the above mentioned modules have been attached internally over a 10-pin pinhead via flat cable which transmits in a serial mode. This cable leads to the control board that the PIC16F876 is on.
The signals of the external input board are also attached to the same control board that the aforementioned PIC16F876 is on. The PIC16F876 processes the signals und transmits them as an 8 bit sized signal over the SPI to each individual module, which inturn produces the correct animation on the displays.
