Title: Multipath LED Display by Using Single Chip Micro-computer Fictitious Serial Port Drive
Abstract: As for multipath LED display, when UART serial port of single chip micro-computer is occupied, fictitious serial port can be used for extension with output in parallel running. By using 89C51 single chip micro-computer fictitious serial port and 74LS164 bit transfer storage device can fulfil multipath LED display, introduction to hardware circuit design was made with analysis on serial port method ZERO time sequence as well as reference program. The multipath LED display system designed with the method is with simple in hardware structure, easy in software programming and low in price etc.
