1. LED display Principle: 16 × 16 dot matrix LED scanning the working principle of the same 8-bit digital tube similar scan. It has a total of 16 cathode output ports, each corresponding to a total of 16 cathode LED display lights, so the scan decoding addresses of four signal lines (sel0-sel3), its characters scanned by the 16-bit code segment address (l0- l15) input. Through the clock out of every scan revealed a complete character. 2. In this study, the achievement of output, " Welcome to the" four Chinese characters, the use of output in two formats: (1) followed by continuous output from right to left (2) a single character from the previous and the next refresh the output.
