VHDL语言编写的I2C通信接口,可与单片机等MCU相连,只占用很少的引脚线完成数据的传输(Written in VHDL I2C communication interface, such as MCU and MCU can be connected, only takes a few lines to complete the data transmission pin)

数字载波发生器，产生一个正弦波，工程中的所有模块都经过测试并运行没有任何问题，而且利用逻辑分析仪对每个模块的输出都进行了逻辑测试。并经过D/A转换得到了正弦波波形，但唯一的缺点是没有滤波器，如果有人想看标准正弦波，可以自制一个简易低通滤波器进行观看，如有不清楚的地方可以把问题发到我的邮箱jiangguoqian@126.com一起探讨研究。(sinewave)

说明：  该代码，只用了硬件描述语言Verilog在完成对SD卡控制器的编写，经济实用(The code, only the hardware description language Verilog in the completion of the SD card controller to prepare, economical and practical)

基于FPGA的16*16点阵中文LED显示，另带有几个简单的中文汉字的点阵数据。(FPGA-based 16* 16 dot matrix Chinese LED display, and the other with a few simple lattice data Chinese characters.)

ALTERA　NIOS处理器实验，编程环境是QUARTUS，在NIOS SHELL下编译实现功能。实验USB接口-Altera NIOS processor experiments, programming environment is QUARTUS in NIOS SHELL compiler functionality. Experimental USB interface

TLC5510的驱动程序，采用Verilog语言编写(TLC5510 driver, the use of Verilog language)

说明：  利用正点院子开拓者fpga实现DDS功能，实现三角波、正弦波、方波的发生。(Implementation of DDS with FPGA)

FFT的MATLAB实现。非常完整的实现FFT过程，速度很快。(The FFT in MATLAB. Contains more than one source, the FFT process. Learning Reference essential)

说明：  通过一个计数器来实现输出信号的占空比要求，可以将duty_cycle分配到拨码开关上,LED分配到发光二极管上,然后调节拨码开关,即可看到LED的亮度发生变化.(The duty cycle of the output signal can be assigned to the dial switch by a counter, and the LED can be assigned to the light emitting diode. Then the brightness of the LED can be seen by adjusting the dial switch.)
