This application note from Texas Instruments describes the hardware design considerations for making a multi-sport scoreboard that is cost efficient, portable, easy to use, and support wireless transmission of display data.
Designing an LED scoreboard
This application report describes the selection of the following: an appropriate LED display, a controller system, a communication system, and software for building the wireless LED-based scoreboard. Different techniques are included to drive the LED display from a microcontroller as well as some test results. This application report is only for displaying numerals on the scoreboard but the same concept can be applied to display alphabets. A similar concept can be extended to large LED-display modules with multiple 16 × 16 or 24 × 24 matrices.
