摘　　要：介绍一种基于EZ-USB FX2单片机的LED点阵显示屏控制系统的实现方法,讨论USB控制器EZ-USB FX2(CY7C68013)的性能,给出该系统的软硬件实现方案,包括CY7C68013的固件程序和计算机主机用户程序。将系统读取的上位机数据通过USB接口传输到FX2单片机,由单片机端点2缓冲区寄存器进行存储,再对数据进行读取和显示,从而实现由FX2单片机完成USB通信及显示控制,省去额外的单片机当控制器。具有友好的人机交互界面和快速实时显示的特点。经过实践证明,该方案实现的LED点阵显示屏系统能基本满足符号和文字显示的需要。An implementation of LED dot -matrix display based on EZ -USB FX2MCUis introduced. The performance of USB controller EZ - USB FX2 （CY7C68013） and its hardware and software implementation are discussed,including firmware design of CY7C68013 MCU and computer host user program. The display data from computer are transmitted to FX2 MCU through USB interface and stored in endpoint 2 register, the data can be read and displayed. Thus the FX2 MCU can complete USB communication and display control, while it can get rid of additional MUC controller; The system has characteristics of fast real - time display and it can provide a friendly interface between human and machine. It is proved that the LED dot - matrix display system based on this solution can satisfy the requirement of symbol and word display.
