  • 景观分析软件 apack
    【实例简介】针对大的数据集进行快速的景观指数计算.景观生态学者对比景观的各项景观指数来景观的时空变化,以及预测景观格局效应。APACK设计的目的是为了开发一种有效的程序来计算景观指数,它是由C++语言写的独立执行的程序,在windows平台上运行,支持的数据格式包括ERDAS GIS文件和ASCII文件。 输出的数据由文本文件和电子表格组成。APACK能计算25个景观指数,这些指数主要包括基本指数(如:面积)、信息论指数(如:多样性)、结构指数(如:孔隙度、连通性)

  • 正点原子STM32F407 DMA+ADC 连续采样24路ADC的值 并且将ADC的值用屏幕显示
    资源是基于Stm32F407的代码,可以在正点原子探索者上面非常好的运行,代码的作用是轮询扫描共计24路的ADC接口并且将 得到的ADC的值保存在数组中,最终通过屏幕的方式显示出来(使用开发板的时候很多IO被内置上下拉,这不是程序错了,是实际的硬件连接导致的,在实际使用中这个是不需要担心)

  • Python3 实现大众点评网酒店信息和酒店评论的网页爬虫
    内容:根据已有的的"大众点评网"酒店主页的URL地址,自动抓取所需要的酒店的名称、图片、经纬度、酒店价格、用户评论数量以及用户评论的用户ID、用户名字、评分、评论时间等,并且将爬取成功的内容存放到.txt文档中。平台:Python 3.5.3;Eclipse for Pydev主程序:DianpingSpider.py注意:设置了时间,模拟器等,较为有效地防止大众点评网的反爬虫结束检测到同一个IP访问频繁而屏蔽爬取,但是未能实现IP代理。
