这是一个nios工程，控制TFT液晶屏的程序。FPGA平台用Verilog HDL语言编写的，MCU软核程序有C语言编写。通过这一个完成的工程，你就会明白SOPC的一些实现方法。(This is a nios engineering, control TFT LCD screen program. The FPGA platform Verilog HDL language preparation with the nuclear program has a soft, MCU written in C language. Through this a complete project, you will understand some of the SOPC methods of realization. )

basys3的数字钟，可以显示00.00-59.59(Digital clock of basys3,It can display 00.00-59.59)

VHDL实现SPI功能源代码 -- The SPI bus is a 3 wire bus that in effect links a serial shift -- register between the "master" and the "slave". Typically both the -- master and slave have an 8 bit shift register so the combined -- register is 16 bits. When an SPI transfer takes place, the master and -- slave shift their shift registers 8 bits and thus exchange their 8 -- bit register values.(SPI realize the functional VHDL source code The SPI bus is a 3 wire bus that in effect links a serial shift register between the )

基于FPGA的OFDM的实现，Verilog语言。(OFDM based on FPGA,by Verilog)

使用sdi 对采集到是视频数据进行解码，转为bt656数据格式的数据进行输出

用三个按键控制pwm输出 key0控制是选着显示/改变频率或占空比 key1控制增加 key2控制减少 数码管显示频率或占空比 频率单位默认Hz（500-20KHz） 占空比范围（0.1-0.9）(Control PWM output with three keys Key0 controls display/change frequency or duty cycle optionally Key1 controls the increase Key2 controls are reduced Digital tube display frequency or duty ratio Frequency unit default Hz (500-20khz) Duty cycle range (0.1-0.9))
