BCD to 7 segments display decoder

基于fpga和51单片机的等精度频率计，通过fpga对信号进行采集，数据传给单片机计算，再由12864进行显示，可进行频率，周期，脉宽，占空比，幅值等的测量。(Fpga and 51 microcontroller based precision frequency meter, through fpga for signal acquisition, data to the microcontroller to calculate, and then by 12864 for display, can be measured frequency, period, pulse width, duty cycle, the amplitude and the like.)

该程序是一个可完成订制化的SPI双向总线接口，时钟相位、极性，以及分频比全部可通过寄存器进行配置，已经在ISE下通过综合，占用资源少，强烈推荐 (The program is a complete custom of SPI bidirectional bus interface, clock phase, polarity, and the divider ratio can all be configured through the register, has been in the ISE through an integrated, small footprint, it is strongly recommended)

基于FPGA的电子密码锁设计与实现，语言是VHDL语言，有注释(FPGA-based design and implementation of electronic locks, language is VHDL language, annotated)

用于检测信号上升沿，输出与时钟相关的正脉冲(Detect the rising edge of the signal)

基于FPGA的AD转换控制器设计，AD7822，quartus II，verilog hdl(A Design of the A/D Convertion Control Module Based on FPGA)

给予QPSK调制的OFDM例程，简单明了的表述了OFDM的通信原理(Given OFDM QPSK modulation routine, simple expressions of OFDM communication theory)
