  • 国外非常流行的步进电机STM32控制代码(加减速、精准定位脉冲、自由调速,绝对精典)
    国外非常流行的步进电机STM32控制代码,S型加减速,启动加速和停止减速可以不同,完成满足各种不同需要,代码中可以随时获取电机已走脉冲(实际就是当前位置),类似PLC中的脉冲计数器,代码的执行效率比DMA方式的还高,基本不占用CPU资源,可以说是非常精典的资料!!

  • 基于点云数据的三维重建
    文章的第二章,从三维激光扫描数据的特点出发,介绍了数据处理的基本程,重点介绍了预处理的内容:其一,介绍了使用FARO Laser Scanner 880的套软件FARO Scene和商业软件Geomagic Studio对点云数据进行去噪的方法步骤;其二,介绍了多站数据配准的基本理论和几种重要算法,包括:有靶控制的点云配准方法、ICP算法和四元数法,并归纳了这几种方法的特点。第三章主要研究了基于塑像三维点云数据进行模型重建的技术。针对塑像面不规则的特点,对塑像点云的建模选择了逐点插入法构建空间三维网格,细介绍了该算法和流程;针对三维激光扫描数据量大的特点,提出了基于构不均匀网格

  • systemverilog验证 (张春) 源代码 (http://chris.spear.net/systemverilog/已经打不开了)
    《systemverilog验证》讲解了SystemVerilog语言的工作原理。介绍了类、随机化和功能覆盖率等测试手段和概念,并且在创建测试平台方而提供了很多引导性的建议。《systemverilog验证》借助大量的实例说明SystemVerilog的各种验证方法,以及如何根据实际的应用情况选择**的方法达到尽可能高的覆盖率。而且,重点演示了如何使用面向对象编程(OOP)的方法建立由覆盖率驱动并且受约束的基本的随机分层测试平台,此外,还论述了SystemVerilog与C语言的接口技术。

  • PCA+GUI的人脸识别
    也是刚学的matlab,学习GUI编程,还是直接看程序,写代码比较好。看书吧,程序敲下来都有不通的。自己结合别人代码稍微改了下,训练和测试库都带了,界面简单明了,可以运行。为了像自己一样的matlab小白,我还写了一个运行指导。简单但是对做识别整个流程很清晰的。
