Design of Intelligent Full-Color LED Display-Screen System Base on ARM and FPGA

Abstract

Full-color LED display-Screen is widely used as a new information display device in all aspects of life, but its flat and static display could not cater to peoples dynamic visual change ,and its lack of intelligence capability makes it a defect not to respond timely with special outside change. ARM and FPGA With high speed and programmable features having been used widely in applications of the embedded development and we provide the method to design of Intelligent Full-Color LED display-screen system based on ARM and FPGA. The control system employs Cortex-M3 core-based ARM as its mail controller, the temperature and humidity sensor, microwave sensor, an infrared sensor are adopted for outside information, and FPGA scan control unit for the color data display. Brushless Direct Current Motor (BLDCM) possessing Superior performance in control unit is widely well applied. The experiments show that the reasonable modular design of the program enables its smooth rotation within the range of 45°-135°, and it timely response to various changes on the outside. Thus LED can display 256 data intelligently which ensures the market prospects. Key words: IntelliSense ; ARM ;FPGA; Full-color LED display-Screen ; Cortex-M3;BLDC motor
