基于FPGA的AD转换控制器设计，AD7822，quartus II，verilog hdl(A Design of the A/D Convertion Control Module Based on FPGA)

出租车vhdl程序，并带有testbench仿真程序，通过开始按键复位，然后根据行使信号进行公里计数，起步价3公里8元钱，超过3公里一公里1元钱(Taxi vhdl program, with a testbench simulation program, started by the reset button, then the exercise kilometer count signal, starting at 3 km 8 yuan, more than three kilometers one kilometer dollar.)

高通滤波器的仿真（由matlab和simulink两种方法实现）源文件以及图片示例(Simulation of the high-pass filter (implemented by the two methods matlab and simulink) source files as well as images example)

FPGA使用串口实现字节拼接传输更大的数据，通过修改代码可以实现任意字节的拼接，并通过自己设定通信协议可以实现与STM32的通信，达到简单而又高效率的通讯效果
