基于LABVIEW的CAN通信实例，有助于CAN通信上位机制作。

dubbo-admin-2.5.7,,,支持JDK1.8.亲测好用！！！！！！！

简单的IMM算法matlab例程含多种仿真模型，两个基本系统模型，并附上详尽实验报告一份。

【实例简介】MQTT 协议+W5500EVB+DHT11模拟实现了手机端可以在外网控制板载LED 灯的亮灭和实时接收 DHT11 采集到的数据，其中 W5500EVB 作为以太网网关，负责将采集 到的温湿度数据加上设定的主题按照 MQTT 协议的要求 PO 到 MQTT 云端，或者在订阅针 对 LED 灯开关控制的主题后从 MQTT 云端接收手机 APP 发过来的对应 LED 灯开关控制的 主题的控制指令。当然，现实的话大神们可以脑补一下用带有蓝牙或者 Zigbee 控制功能的 灯泡或家电设备，开发板这边也加上接收模块…这是后续需要完善的，手机 APP 怎么做的 下次有机会再讲，这次先把 MQTT 以太网网关怎么实现的，以及如何采集 DHT11 数据等方 法给大伙儿分享下。

用QII 9.1做的，可以实现加减速、启停、正反转、旋转圈数计数

可以用于unity3D的fbx格式的飞机、坦克、舰船三维模型

LabView手绘波形工程文件，1）利用LabVIEW以及实验室的信号采集设备，实现任意波形发生器的功能。该信号发生器除了能够产生正弦波、方波、三角波和锯齿波四种典型波形，还能根据输入的公式产生公式波形，幅值、频率等均可以调节。（2）通过手绘实现任意波形的输出。输出的信号均可以与幅值可调的均匀白噪声进行迭加。要求：要求高精度和高可靠性，实时性。界面友好，易于操作

本人对GPS的信号抗干扰算法的一些论文的收集，主要包括自适应盲波速形成算法，抗窄带干扰算法，空时域联合抗干扰算法等~
