组合电路与时序电路的 VHDL 代码

VHDL实现了IIS接口程序，在Quartus II 6.0上编译通过，在板子上可以读取IIS数据-IIS VHDL interface procedures, the Quartus II 6.0 compiled by the board can read data IIS

FPGA的仿真实例，Verilog代码编写，过程详尽，代码易懂。-FPGA simulation examples, Verilog coding, the process in detail, code easy to understand.

4通道12位AD芯片 AD7862控制模块,VHDL源代码,适于单次转换采样,250K采样率.-4-channel 12-bit AD chip AD7862 control module, VHDL source code, suitable for single conversion sampling, 250K sampling rate.

将VHDL程序下载到DE2开发板，引脚分配时需要知道的芯片每个引脚功能(VHDL program will be downloaded to the DE2 development board, you need to know when the pin assignments for each pin of the chip functions)

RS(255,223)编解码算法。verilogHDL代码实现，在XILINX的芯片上得到验证。不包含任何IP核，方便移植到任何FPGA芯片。(RS (255223) encoding and decoding algorithm. VerilogHDL code to achieve, in the XILINX chip to be verified. Does not contain any IP core, easy to transplant to any FPGA chip.)

说明：  有自己制作的下载器原理图，包含了stlinkv2,XDS100V3,USBBLASTER.原理图和封装，一款多功能下载器。(Have their own production downloader schematic diagram, contains stlinkv2, XDS100V3, USBBLASTER. Schematic diagram and encapsulation, a multi-function downloader.)

大屏幕led点阵显示的驱动时序。 使用vhdl语言描述。其中rom文件可以使用lpm_megcore自动生成。-big screen led to the dot matrix display driver timing. The use of VHDL description language. Rom which documents can be automatically generated using lpm_megcore.

用VHDL实现十六位移位乘法器 才有移位相加法来实现-Use VHDL to achieve 16-bit shift multiplier shift only the sum of law to achieve

说明：  DAC3283 寄存器初始化，SPI驱动(Dac3283 register initialization, SPI drive)
