Using the Arduino libraries for regular AVR code

这一生的挚爱 提交于 2019-12-03 04:22:21
问题 I have an Arduino Uno and a Linux environment. Though the Arduino IDE is great and all, however it doesn't give me much inputs if something goes wrong. And it also becomes excruciatingly slow and stops communicating with the chip sometimes. The alternative is to code my Arduino Uno using the AVR-GCC/g++ and AVRDude toolchain. However, I would very much like to have access to the same functions as in Arduino (like Serial, digitalWrite, etc.) while programming using a simple text editor and

Remove Qt libraries on Mac

I want to remove the installed Qt 4.8 libraries and install Qt 4.6 libraries on my mac. But when I try to install them I get: "Qt libraries cannot be installed on this disk. A newer version of this software already exists on this disk" I removed the /usr/local/Qt4.8.x folder from the disk but the message is still here. How can I remove the old libraries? You shouldn't manually delete a folder unless there is no other option. You should try running the uninstall script first: sudo python /Developer/Tools/uninstall-qt.py The path to this script will be different if you are running the latest

Essential Swing libraries? JGoodies, JFreeChart [closed]

The wheel is invented over and over again - at least it seems so when looking at any average Swing GUI project. In many areas there are one or two very well known libraries for things not directly addressed by the standard class library, e.g. hibernate for persistence. But things seem a little less clear for GUI applications - what are the libraries you see as essential for almost any new GUI project? I'd propose JGoodies as a start. And for anything involving displaying data graphically maybe JFreeChart. For more sophisticated components SwingX - I have never used it but I hear it often

python libraries for ssh handling

人盡茶涼 提交于 2019-12-03 03:11:43
问题 I'm going to write first code for handling ssh commands on python and I did search over the stackoverflow and can see that there are several python libraries that can be used for handling commands passed through ssh, like paramiko, pexpect and perhaps some others. Particularly, I will need to read content of the files from the remote server, copy files through ssh/scp, get output from remote server after starting the script on remote server. Perhaps some experts could advice what library is

What good libraries are there for solving a system of non-linear equations in C++?

与世无争的帅哥 提交于 2019-12-03 02:59:13
In a C++ application I'm coding, I need to solve a system of non -linear equations (N equations, N unknowns). The systems I'm solving will be rather small (up to 10 equations/unknowns), so performance is not going to be a real issue. I've searched the web a bit for a non-linear solver library, and I couldn't get to something which looks easy to use (got to NOX and C/C++ Minpack , but both seem to be an overkill for my need). Any thoughts and ideas of easy-to-use libraries for this purpose? There are two options for you, you can use the sundials packages which includes a nonlinear solver,

Where should I put third-party libraries?

筅森魡賤 提交于 2019-12-03 02:41:08
I contribute to a decent-sized C++ project with a number of dependencies. The problem is, the project contains the source of all of its dependencies (e.g. pcre, zlib, etc.). I want to trim the project down to just what's relevant to the program itself. Is there some relatively standard way to compile these libraries and put them somewhere, and have their header files also easily accessible? For what it's worth, I'm using Windows 7, and I'm developing using VS2005. I'm also a complete noob with working on large C++ projects on Windows; I've never really needed to step outside the standard

If you feel that this question can be improved and possibly reopened, visit the help center for guidance. Closed 6 years ago . Just wondering if anyone knows of a web-scraping library that takes advantage of Scala's succinct syntax. So far, I've found Chafe,

What scalability issues are associated with NetworkX?

浪子不回头ぞ 提交于 2019-12-03 01:39:37
问题 I'm interested in network analysis on large networks with millions of nodes and tens of millions of edges. I want to be able to do things like parse networks from many formats, find connected components, detect communities, and run centrality measures like PageRank. I am attracted to NetworkX because it has a nice api, good documentation, and has been under active development for years. Plus because it is in python, it should be quick to develop with. In a recent presentation (the slides are

Node.js Logging

问题 Is there any library which will help me to handle logging in my Node.Js application? All I want to do is, I want to write all logs into a File and also I need an options like rolling out the file after certain size or date. I have incorporated log4js im trying to keep all the configuration details in one file and use only the methods in other application files for ease of maintenance. But it doesnt work as expected. Here is what I'm trying to do var log4js = require('log4js'); log4js
