VERILOG比较器设计

滤波器 Generaic FIR Filter(Generaic FIR Filter)

CAN VHDL Code. Behavioral implementation of CAN bus interface.

说明：  此代码为使用SPI 用于实现28335控制AD9959输出信号的频率、幅度(This code uses SPI The Frequency and Amplitude of AD9959 Output Signal Controlled by 28335)

Verilog codes of UART modules and guidances of UART

16 bit switch input view in hexa format on 7seg display

例程是基于quartus的，FPGA通过EMIF给DSP发送数据，里面包含了一个简单的状态机和一个基于IP核的fifo，适合初学者(Routine is the FPGA to send data to the DSP via EMIF, which contains a simple state machine and an IP-based core fifo, suitable for beginners)

Termometric 代码 DAC 的 14 位到 76 位 Verilog 语言。源 decoder.v 和 decoderTB.v

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.)

这是我自己写的一个摄像头数据存储SD卡程序，quartus的verilog编写，摄像头采用自己添加的外设接口，数据采用dma采集，SD用的是软件自带的SPI内核以及znFAT的文件系统。帧率我没有测，有兴趣的可以测测，初学者可以参考学习，写的代码有点乱，如果有不懂的可以和联系。(This is what I wrote it myself a camera, SD card data storage program, quartus the verilog write, add their own camera with peripheral interfaces, data acquisition using dma, SD with the software that comes with SPI znFAT kernel and file system. I did not measure the frame rate, are interested can Cece, beginners can refer to the study, wrote the code a bit messy, if there do not understand can contact)

说明：  xilinx 平台的SPI从接口实现源码，供参考学习(used xilinx,slave-spi interface.)
