国外大牛 Andrew Fitzgibbon写的ICP算法实现代码，含2D和3D，工具包，可以打开主目录下的Untitled3看一下效果。

关于自适应波束形成方面的几个准则和相应matlab代码，有注释，能成功运行

数据采集适合于测试信号的采集与分析 该设计简单易学适合于初学者的选用

HT-001 RN8209电表套件(STM32不带电能)，带全部的电路原理图，软件源代码和相关设计文档。

ArcEngine中的ILegend和ILegendItem使用起来总觉得不让人满意，特别是AdjustColumns和Item。因此把PageLayout的图例想象成很多Element的组合，基于IElement重新实现了图例类。图例类的类图可以参考附件中的图例绘制.bmp。另外，附件中有示例程序，示例mxd，还有源码。

强力推荐的ISAR程序代码，自己调试过，可以运行，对学习雷达成像的朋友很有帮助！

基于FPGA的洗衣机控制器设计，主要通过使用VerilogHDL语言，在Quartus2上完成电路设计以及程序开发模拟。实现以洗衣机控制器为核心，加上必要的外围电路，能够对洗衣机工作状态自由控制。全部程序由控制器模块，分频模块，按键去抖模块，显示译码模块组成，顶层模块使用原理图实现，底层由Verilog HDL语句实现。核心控制器FPGA根据控制端口的信号输入，向洗衣机发出正传，反转，待机信号，并通过数码管和LED灯显示当前的工作状态以及工作时间。该洗衣机控制电路可以方便快捷的实现对洗衣机的控制和状态的显示功能，同时具有紧急暂停待机功能，保证控制的可靠性，以及洗涤循环次数报警功能，提高任务精度
