欢迎大家使用该程序，是在FPGA下使用开发的。请大家使用。

adc采集多路采集多通道基于dma的adc采集(ADC acquisition, multi-channel acquisition and multi-channel acquisition)

基于Verilog HDL的完整数字跑表工程，在试验机台上运行验证通过了的。 用8位7段数码管分别显示微妙，秒，分。 有开始，暂停，复位功能。 学习VerilogHDL的经典例子，添加了显示功能。-Complete Verilog HDL-based digital stopwatch works in the test machine is running verify pass the platform. With 8-bit 7-segment digital tube showed the delicate, seconds, minutes. Has started, pause, reset. Learning VerilogHDL classic example of adding a display.

脉冲宽度调制，VHDL代码编写，包括QUARTUSII和MODELSIM工程以及testbench-Pulse width modulation, VHDL coding, including QUARTUSII and ModelSim engineering and Testbench

基于sopc ep2c5开发板的rs232例程-On sopc ep2c5 development board rs232 routines

ARM7系统IP核的VHDL语言源代码，需要的开发环境是QUARTUS II 6.0。(ARM7 System IP Core VHDL language source code, the need for the development environment is QUARTUS II 6.0.)

DAC0832的Verilog代码，适用于与ADC0809同时学习，效果明显！(DAC0832 Verilog code, applicable at the same time with ADC0809 learning, the effect is obvious!)

this project is about FIR FIlter By VHdl codes in the ISE.

说明：  DDS的基本原理主要由五部分组成，分别是；相位累加器，正弦波形存储器，数模转换器，低通滤波器和时钟，将相位累加器输出的数据作为地址，用来查询表的数据，将取出的正弦数据通过数模转换器输出模拟信号，模拟信号再通过一个低通滤波器输出纯净的正弦波信号。(The basic principle of DDS is mainly composed of five parts: phase accumulator, sinusoidal waveform memory, digital to analog converter, low-pass filter and clock. The output data of phase accumulator is used as address to query the data of table. The extracted sinusoidal data is output analog signal through digital analog converter, and the analog signal is output pure sine through a low-pass filter Wave signal.)

说明：  FPGA控制AD7321的模块，是本人亲自试验过的。有Verilog源码，和简单文档。(FPGA control module of the AD7321 is personally tested. There Verilog source code, and simple document.)

高速ADC及DAC接口的参考设计。在Xilinx FPGA上实现。(Reference design of xapp1071.)
