Abstract

Based on the technology of the high performance ARM microprocessor of embedded real-time operating system, a kind of large LED color screen display control system was designed. This Article mainly analyzes the design of LED display control. High performance 32-bit ARM9 microprocessor is used as the core control to achieve a variety of dynamic display effect. And it combined with FPGA technology to solve the problem that now the LED display screen can´t satisfied with the large display area and the switched frequently display data requirement. GSM is used in this system as communication line to update the memory data wirelessly. This system can run for a long time succession, steady and reliability.
