基于MAX2运用Quartus实现串口通信

此代码帮助您在spartan系列fpga上设计交通灯控制器，并使用FSM模型进行设计，使设计更简单，也更易于理解；

说明：  verilog编写的RS485读写驱动程序(RS485 read-write driver written by Verilog)

用verilog写的4*4小键盘按键检测程序。本工程已经编译好。可以直接在Atera DE1 Fpga开发板上运行-Written using Verilog 4* 4 keypad keys detection procedures. The project has been compiled. Directly in the development of Atera DE1 Fpga board run

VHDL语言描述的二进制十进制译码电路，已经编译完成-Binary decimal decoder circuit

适用于FPGA的SOPC方面的元器件添加，如COMPNENT-Applicable to FPGA-SOPC area to add components, such as COMPNENT

七人抢答器 可做课程设计 能仿真 一人抢完其他人锁定-qiren qiangdaqi ke fangzhen

基于FPGA的DDS。可以产生三种波形：正弦，方波，三角波。频率分辨率0.012Hz。频率从0至25MHz任意可调。(FPGA-based DDS. Can produce three waveforms: sine, square, triangle wave. Frequency resolution 0.012Hz. Frequency is adjustable from 0 to 25MHz.)

本文使用实例描述了在 FPGA/CPLD 上使用 VHDL 进行分频器设 计，包括偶数分频、非 50％占空比和 50％占空比的奇数分频、半整数 （N+0.5）分频、小数分频、分数分频以及积分分频。所有实现均可 通过 Synplify Pro 或 FPGA 生产厂商的综合器进行综合，形成可使 用的电路，并在 ModelSim 上进行验证。 -This article describes the use of examples in the FPGA/CPLD prescaler to use VHDL to design, including the even-numbered sub-frequency, non-50 duty cycle and 50 duty cycle of the odd-numbered sub-frequency, semi-integer (N+ 0.5) sub-frequency, fractional-N, as well as scores of sub-band frequency points. All can realize through the Synplify Pro or FPGA manufacturers integrated synthesizer to form a circuit can be used and verified in the ModelSim on.
