EP2C35A实验箱基于NIOSII的串行AD_DA编程(EP2C35A experimental box based NIOSII the serial AD_DA programming)

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.)

本程序实现流水线功能，您可根据自己需要更改参数，试用芯片xilinx，用verilog语言编写(This program implements the pipeline, you may be required to change the parameters according to their own try xilinx chip with verilog language)

VHDL语言，设计一个在DE2平台的8个七段数码管上循环显示HELL0的程序，采用按键控制循环的速度，慢速循环时间间隔为1S，快速循环时间间隔为200ms。(VHDL language, design a platform in the DE2 8 segment digital tube display HELL0 program cycle, the speed control loop using keys, slow cycle time interval for the 1S, fast cycle time interval is 200ms.)

在BASYS3上实现跑马灯的功能。第一LED交替闪烁；第二LED由左至右逐个变亮，再逐个变暗；第三LED由右至左逐个变亮，再逐个变暗；第四LED由两边逐个变亮，再从中间逐个变暗。(Realize the function of the horse light on BASYS3. The first LED flashes alternately; second LED brightens from left to right and then darkens one by one; the third LED turns from right to left, then darkens one by one, and then darkens one by one; fourth LED is brightened by both sides, and then darkening from the middle.)

verilog程序仿真滤波器 16阶 运用加法器和乘法器 40KHZ 16位并入并出

基于旋转编码器和LED灯组的强度调节系统设计(Design of Intensity Regulation System Based on Rotary Encoder and LED Lamp Set)

说明：  使用FPGA的FIFO，状态机，乒乓操作等实现了异步UART。(The use of FPGA-FIFO, state machine, ping-pong operation to achieve the asynchronous UART.)

在FPGA平台实现SPI传输协议开发，SPI为三总线式。(Implementation of SPI transmission protocol development on FPGA platform)
