FPGA入门点亮一个LED灯，作为FPGA入门级程序(FPGA is)

spartan-3e fpga vhdl 实现的计数器 记满后点亮小灯(spartan-3e fpga vhdl counter to light led)

说明：  STM32F103 ADC 通过DMA进行读取(STM32F103 ADC reads by DMA)

DDS 产生正弦信号，OOK，AM三种波形。 使用xilinx FPGA VHDL(DDS. Resulting in sinusoidal signal, OOK, AM three waveforms. Using xilinx FPGA VHDL.)

本文首先对多功能车辆总线的基本原理进行了简要的概述，接着对其实时协议进行了分析，然后对 MVB2 类设备控制器的功能及其功能模块的划分设计进行了详细的分析；最后对各功能模块进行了编程实现，并给出了仿真验证波形。(Firstly, the basic principle of the multifunction vehicle bus are briefly outlined, then analyze the real time protocol, then carried out a detailed analysis of the classification of the design function and the function module of the MVB2 device controller; finally, the function of each module of the program, and gives the simulation waveforms.)

在BASYS3上实现跑马灯的功能。第一LED交替闪烁；第二LED由左至右逐个变亮，再逐个变暗；第三LED由右至左逐个变亮，再逐个变暗；第四LED由两边逐个变亮，再从中间逐个变暗。(Realize the function of the horse light on BASYS3. The first LED flashes alternately; second LED brightens from left to right and then darkens one by one; the third LED turns from right to left, then darkens one by one, and then darkens one by one; fourth LED is brightened by both sides, and then darkening from the middle.)

说明：  VHDL语言写的SRAM控制程序，在开发板上验证过。(Written in VHDL SRAM control procedures, the development board verified.)

整理的网上关于LCD12864(ST7920控制器）的串并口程序，已在stc89c52rd+11.0592MHz的情况下测试通过(Finishing line on LCD12864 (ST7920 controller) serial and parallel programs, in the case of stc89c52rd+11.0592 MHz test)

基于高清视频的3D人脸识别源代码，四万多行，经过FPGA实际验证，最近调试完毕。(The source code of 3D face recognition based on HD video, more than 40,000 lines, has been verified by the actual FPGA, and has been debugged recently.)
