Along with the technical development in calculator, the modern calculator is all a large-scale integrated circuit calculator they have the function strong, the construction tightly packed, system is been together by etc. characteristics, its development trend is a giant turning, the miniaturization, network turns and the intelligence turns.The miniaturization is an important direction that calculator develop, and also is to carries the calculator calculate the machine, controller,
saving machine, I/ O pick up a people four constitute the part gathers in a silicon slice, hence appeared a microcomputer for regarding large- scale integrated circuit as principle constituting the namely single a machine.( Single Chip Microcomputer) exactly because of single technical development in a machine, then can make LED (Light Emission Diode) seven figureses tube can under the situation of the decrease drive the machine can directly drive drive.Because the LED(Light Emission Diode figures tube shows that the technical advantage makes it applied by extensively control in the industry process the system, intelligence appearance, intelligence product etc. realm.This thesis point introduced LED(Light Emission Diode) figures tube dynamic manifestation technique and static manifestation techniques, and analyzed each from of merit and shortcoming, and the plait writes the key coding that these two kinds of manifestations technique realizes in single a machine and provides to consult principle Chien's diagram.And introduce the constitute of LED(Light Emission Diode), the manifestation principle and ameter 、electronic counter 、doing exercise to keep fit in the application on the car and RDY-68 wireless
data transmission system.
【Key word】: Single Chip Microcomputer,The figure tube ,The dynamic manifestation technique, The static manifestation technique.
