用VHDL和verilog实现的四人抢答器-using VHDL and verilog realization of four Responder

It s Flicker_LED code.Verilog for MaxV.

FPGA读取LM75A温度数据，并在段码LED上实时显示。(The temperature data of LM75A are read by FPGA and displayed on segment code LED in real time)

uart documentation, july 17, 2019. the document describes the basics of verilog programming and how to implement them on an fpga device

说明：  I2C完整代码，可综合，可仿真，已经过验证(I2C code can been syn and simulation ,veritify)

基于FPGA DE0以及niosII的射频无线发送程序,采用spi接口操作无线模块nrf24l01(To spi interface operation wireless module nrf24l01 of FPGA DE0, as well niosII RF wireless transmitter program)

采用SG3525实现感应加热电源的频率跟踪。(SG3525 is used to realize frequency tracking of induction heating power supply.)

模拟SDH帧结构，设计了状态机，能从连续传输的SDH字节流中找出帧头；从SDH字节流中，提取E2字节，并按照64K速率分别串行输出E2码流及时钟；设计了输入信号，输出包括E2串行数据、E2串行时钟和SDH帧头位置指示

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)
