Single-chip programming: Let the LED digital tube display the number 0 to 9

LED digital tube is widely used in single-chip microcomputer system, it is composed of light-emitting diode. The digital tube consists of 7 LEDs of a "day" shape, if the need to display the decimal point, then add a point, is a 8-segment digital tube.

Digital tube Display high brightness, the corresponding speed, sub-common cathode and common anode two forms, commonly used have a single and 4-linked, there are two and dedicated to display time.
