tdma参数化模块。可以自动生成2的n次的tdma哥时隙，用户可根据需要自己配置参数(tdma see the number of model lumps. 2 n basis following manner tdma chance possible 以自 dynamic generation, for root needed self-placement see number)

this example finds the gapes that are existed in a word

共两个文件，一个是对网络芯片W5500进行控制的master spi接口，另一个是w5500命令控制逻辑，命令格式按照w5500芯片的要求，分为地址段，控制段和数据段进行统一控制。此外提供w5500芯片初始化及读写控制流程图。(A total of two documents, one is the master SPI interface for network control chip W5500, the other is a w5500 command control logic, command format in accordance with the requirement of w5500 chip, divided into address segment, unified control and data segments. In addition to provide w5500 chip initialization and read and write control flow chart.)

利用数字电路知识，进行二十四小时计时，并有闹钟与蜂鸣器功能-Knowledge of the use of digital circuits, the 24 hours time, and there is an alarm clock function and buzzer

16点FFT，简单易理解，适合初学者了解(16 point FFT, simple and easy to understand, suitable for beginners to understand)

我自己当初用来求解arctan 暂时没有搞成ip形式 搞好了还要传git 这个代码还没有搞好，因为急需要下载东西 如果感兴趣可以联系我 邮件(this is a not full wrappered code very crude use chebyshev to caculate arctan function i m urgent to download a model from pudn so i do this.)

FPGA——IP_RAM实验： 创建IPRAM核，单端口，10位地址线（256字节），8位数据线（每字节8byte），读写使能 input [9:0] address; input clock; input [7:0] data; input wren; //置1则写入 output [7:0] q; LNXmode：控制LEDC显示 1：mode1，从k1~k3输入data的低4位，ledb计时，从0~f，计时跳变沿读取k1~k3的值，存入RAM 8个数之后，从RAM输出数据，用leda显示，同样每秒变化一次(The experiment of FPGA-IP_RAM: Create IPRAM core, single port, 10 bit address line (256 bytes), 8 bit data line (8 byte per byte), read and write enablement)
