程序设置了fpga 的 5x5点阵驱动程序，代码相对比较简洁，这个程序可以作为fpga输出控制，驱动稳压芯片工作，进而点灯

这是我从网上找到的用vhdl语言写的sdram控制器的代码。我的邮箱：wleechina@163.com-This is what I found online vhdl language used to write the sdram controller code. My mail : wleechina@163.com

例程是基于quartus的，FPGA通过EMIF给DSP发送数据，里面包含了一个简单的状态机和一个基于IP核的fifo，适合初学者(Routine is the FPGA to send data to the DSP via EMIF, which contains a simple state machine and an IP-based core fifo, suitable for beginners)

基于fpga的led点阵控制系统软件程序设计(Led dot matrix control system based on fpga software program design)

若农场路无车辆，则在高速路保持绿灯。在探测农场路有车辆，高速路上的交通灯应由绿到黄，再到红，并允许农场路方向灯变绿，绿灯亮一段时间，由绿变黄再到红。(If there is no vehicle on the farm road, keep the green light on the highway. There are vehicles on the farm road, the traffic lights on the high speed road should be green to yellow, and then red, and allow the farm road lights to turn green, the green light for a period of time, from green to yellow, then to red.)
