本书以西门子S7-200 型可编程控制器（PLC）为蓝本，书中介绍的130 个编程实例，均是从作者长年潜心研究、反复推敲的实例中精心挑选出来的，具有很强的实用价值。实例设计时尽量考虑短小精悍、突出重点，每个编程实例都给出了较为详细的编程说明，以便于理解。细心阅读定可体验出其中的编程技巧和精妙之处。

【实例简介】FreeRTOS入门手册无水印版本，原版名字是：《Using the FreeRTOS Real Time Kernel - A Practical Guide》；本文档是RreeRTOS入门的很好的资料，非常有价值！

2017年最新vivado的license，测试可用，拿去不谢~

在linux下安装kettle后，会需要安装几个依赖包：# yum -y install epel-release# yum -y install webkitgtk# yum -y install redhat-lsb其中，# yum -y install webkitgtk可能会报没有可用的包，此时在kettle中点击右上角的connect会报错。那么下载此rpm包后，使用rpm -ivh web*.rpm 就可以了。

AuroraDataRecovery　可恢复分区丢失，分区打不开，误删除 误格式化等多种情况的数据 ，多种恢复方式针对不同的情况采用最合适的恢复方案，另外针对磁盘打不开提示未格式化或者目录或目录损坏且无法读取等状况也可以用RAW恢复。
