本帖最后由 黄瓜 于 2014-3-2 21:39 编辑 在2012年，帖子“圆点博士微型四轴飞行器开工拉...有钱出钱，没钱出力” http://www.amobbs.com/thread-5504090-1-1.html得到坛友的大力支持。经过2013年的全年发展，资料已经相当成熟。楼主把全部资料整理到了一起，方便大家下载。 首先给大家介绍下这些资料的内容：(全部是源代码，豪无保留)： 1,小四轴飞行器源码：包括陀螺仪芯片驱动代码，数字滤波，四元数姿态解算和电机控制代码，此外，还包括蓝牙无线传输代码，NRF24L01+无线传输代码，小四轴无线更新固件代码。 2,小四轴手持遥控器源码。包括USB转COM口代码，蓝牙编程代码，摇杆控制代码，和液晶屏显示代码。通过该代码，用户可以学习USB编程，蓝牙编程，摇杠编程，液晶屏显示编程能知识。 3,基于windows/Linux下的上位机代码，能过获取小四轴姿态，并对小四轴进行飞行控制。该代码使用垮平台算法QT编写。 4,基于Android的手机遥控器代码，可以实现对小四轴的飞行控制 5,对国外著名开源crazyflies开源算法的姿态部分的移植(已修改成大家熟知的MDK环境)，带FreeRTOS操作系统。

matlab有限元网格划分程序 DistMesh is a simple MATLAB code for generation of unstructured triangular and tetrahedral meshes. It was developed by Per-Olof Persson (now at UC Berkeley) and Gilbert Strang in the Department of Mathematics at MIT. A detailed description of the program is provided in our SIAM Review paper, see documentation below. One reason that the code is short and simple is that the geometries are specified by Signed Distance Functions. These give the shortest distance from any point in space to the boundary of the domain. The sign is negative inside the region and positive outside. A simple example is the unit circle in 2-D, which has the distance function d=r-1, where r is the distance from the origin. For more complicated geometries the distance function can be computed by interpolation between values on a grid, a common representation for level set methods. For the actual mesh generation, DistMesh uses the Delaunay triangulation routine in MATLAB and tries to optimize the node locations by a force-based smoothing procedure. The topology is regularly updated by Delaunay. The boundary points are only allowed to move tangentially to the boundary by projections using the distance function. This iterative procedure typically results in very well-shaped meshes. Our aim with this code is simplicity, so that everyone can understand the code and modify it according to their needs. The code is not entirely robust (that is, it might not terminate and return a well-shaped mesh), and it is relatively slow. However, our current research shows that these issues can be resolved in an optimized C++ code, and we believe our simple MATLAB code is important for demonstration of the underlying principles. To use the code, simply download it from below and run it from MATLAB. For a quick demonstration, type "meshdemo2d" or "meshdemond". For more details see the documentation.

Introduction jSMPP is a java implementation (SMPP API) of the SMPP protocol (currently supports SMPP v3.4). It provides interfaces to communicate with a Message Center or an ESME (External Short Message Entity) and is able to handle traffic of 3000-5000 messages per second. jSMPP is not a high-level library. People looking for a quick way to get started with SMPP may be better of using an abstraction layer such as the Apache Camel SMPP component: http://camel.apache.org/smpp.html Travis-CI status: History The project started on Google Code: http://code.google.com/p/jsmpp/ It was maintained by uudashr on Github until 2013. It is now a community project maintained at http://jsmpp.org Release procedure mvn deploy -DperformRelease=true -Durl=https://oss.sonatype.org/service/local/staging/deploy/maven2/ -DrepositoryId=sonatype-nexus-staging -Dgpg.passphrase=<yourpassphrase> log in here: https://oss.sonatype.org click the 'Staging Repositories' link select the repository and click close select the repository and click release License Copyright (C) 2007-2013, Nuruddin Ashr uudashr@gmail.com Copyright (C) 2012-2013, Denis Kostousov denis.kostousov@gmail.com Copyright (C) 2014, Daniel Pocock http://danielpocock.com Copyright (C) 2016, Pim Moerenhout pim.moerenhout@gmail.com This project is licensed under the Apache Software License 2.0.
