Using VHDL realize CPLD (EMP240T100C5) of the PWM output

基于tus5000评估板的VHDL源代码，用于超声波检测，xinlinx提供的(Based on the VHDL source code tus5000 uation board, used in ultrasonic testing, xinlinx provide)

串行数据开发实用代码， 适合初级学习者使用 很不错(Serial data to develop a practical code for primary learners use very good)

FPGA实现乒乓球游戏 代码及仿真 VGA实现(FPGA realizes table tennis game code and simulation VGA implementation)

数字频率测量器，脉宽测量器。可测量多种频率波形的脉宽。(Digital frequency measurement device, pulse width measurement device. Measurement of the waveform of frequency pulse width)

This an interpolating by 2 half-band filter with 79 taps (40 none-zero coefficients).

DE2 altera board vhdl design

verilog编程语言的讲解，有电子科技大学出版(verilog programming language to explain, there is the University of Electronic Science and Technology Publishing)

利用FPGA串口通信向上位机发送数据，使用RS232通信协议，向上位机发送8位数据，其中8八个数据位包括4个信息位，经过7-4汉明编码变为7个信息位，而最低位补0，发送的8位数据为2个16进制数，其2个16进制数通过数码管显示。

这是“VHDL设计”讲稿，希望对初学者有用，-"VHDL design" script, useful for beginners, thank you! !

FM接收机 基于FPGA的调频收音机的设计 用VEIRLOG语言编程，利用QUARTUSii与MODELSIM联合仿真(FM receiver on FPGA FM receiver design With VEIRLOG language program, use QUARTUSii and MODELSIM joint simulation)
