摘要
鉴于传统的LED显示规模小、可靠性差、需要上位机实时控制的问题,提出一种基于FPGA和2片SRAM的嵌入式大屏幕LED显示的方法,其显示规模达到512×512点阵列,并且可以在完全不需要上位机控制的情况下实时独立的工作。本设计已经实际使用在现场厂房中,能够较好地对厂房中的生产情况进行实时显示。着重讨论该系统最底层的硬件连接及相应的软件设计,并给出其软、硬件实现。
On regard of the tradional LED screen which scale is relatively small, reliability is poor and to be controlled by desktop,the paper hands out a way which is based on one FPGA and two SRAMs,could implement the scale 512×512 ,and be able to work independently. The design has been implemented in workshop, it can display the work circumstance in the workshop well. The paper emphasizes the connections of hardware and the design of software.
