友晶 altera DE2开发板中文用户手册，对DE2开发板的完整介绍。(DE2 development board Chinese user manual, a complete description of the DE2 board.)

This CAN Controller was tested with the Bosch VHDL Reference Model and passed all the tests. Because of the licensing issue it can not be published on the Opencores web site. The Can Controller was also implemented in real HW (12 boards were constantly talking to each other). The included test bench is not a real test bench and should be improved. However a volunteer is needed for such a job. I can provide some help but am not willing to write it by myself.

使用verilog写的频率计，可切换档位(Frequency counter using verilog write switch stalls)

说明：  “基于 ROM 的 LCD图片显示实验 ”中利用 FPGA 片上存储资源存储图片，并通过 LCD接口将图片显示到 LCD屏幕上。但是由于 FPGA 片上存储资源有限，只能存储分辨率较小的图片(In the experiment of LCD image display based on ROM, FPGA on-chip storage resources are used to store pictures, and the pictures are displayed on LCD screen through LCD interface. However, due to the limited on-chip memory resources of FPGA, it can only store images with smaller resolution)

FPGA实现BPSK调制，带Modelsim仿真，实际系统测试通过，载波信号，调制波信号频率可调(FPGA implementation BPSK modulation with Modelsim simulation, the actual system test, the carrier signal, modulated wave signal frequency adjustable)
