I have only tried it with Ubuntu. It's probably possible to set it up in Windows, but I don't know how.</p> <p>When you have followed the instructions you're ready to use the Maple without the IDE. The most basic form is to use your favorite editor to write your program in and type "make" on the command line to compile and "make install" to put the program on the Maple. If you have more than one source file you have to add them to the file build-targets.mk (included by the Makefile), but they (leaflabs) say they're going to make a better structure for this. But for now it works.</p> <p>When it comes to Eclipse, I'm just a newbie, but here's what I did.</p> <p>Create a new C++ project and select an empty Makefile project and choose "-- Other Toolchain --".<br /> Add the files main.cpp, Makefile, build-targets.mk from a Maple example.</p> <p>To build the project Eclipse want's to run "make all", but that target isn't implemented in the Maple Makefile (you can add it or) so I went to "Project Properties" to do some configuration:</p> <p>First in "C/C++ Build" first create a new configuration, "Maple", in "Manage configurations" and select that as "Active".</p> <p>In the Behaviour tab remove the word "all" from "Build (incremental Build)"</p> <p>Now you can compile the program with, for example, the build project button.</p> <p>Some other things I did was: in "Project properties | C/C++ General | Paths and Symbols | Includes | GNU C++" remove the include directories and add (at least)</p> <pre><code>{LIB_MAPLE_HOME}/wirish {LIB_MAPLE_HOME}/libmaple</code></pre> <p>And under Indexer make sure to use Maple as "Build configuration for the indexer".</p> <p>Finally to be able to upload the program to the Maple, you want Eclipse to run "make install". I did it by adding "install" to Project|Make target|Build... (in the menu).</p> <p>There's probably more things to do (or better ways to do it than I did), but maybe you can teach me (or us) when you're up and running :-).</p> <p>(And here's what pops up in Eclipse when you hold the mouse over pinMode:<br /> <pre><code>/** * Configure behavior of a GPIO pin. * * @param pin Pin to configure. One of: 0-38 (pin numbers as labeled * on silkscreen), or D0-D38 (symbols for same) * @param mode Mode corresponding to desired pin behavior. * @see WiringPinMode */ void pinMode(uint8 pin, WiringPinMode mode);</code></pre> ) ;-) </p> http://forums.leaflabs.com/topic.php?id=270#post-2113 Fri, 29 Oct 2010 07:55:06 +0000 anotherDJ 2113@http://forums.leaflabs.com/ <p>Thanks everybody for the responses...</p> <p>what is a color organ; its basically an old likes 70's disco light thing that split up high low and mid of a sound audio signal and blinked lights in sync with each component. what we are making is a tool for small bands to use and a light show... So take in audio, process it and do lighting that's catered to their music sort of a visualizer using real lights. </p> <p>Why Eclipse, currently i'm on a co-op term writing firmware, and we use eclipse with C/C++ plugin which i have gotten really used, and i also like the ability to drill down on functions, and multiple file support. But the biggest reason is the others in my team are more familiar with eclipse or visual studios (I blame uncle Gates for that... who teaches C# and C++ EE students I don't know) and they are really wanting the ability to code in one of the two.</p> <p>snigelen, thats awesome! would u be able to give me some pointers as to where to start.

That may be a better approach if eclipse is essential. If you are very familiar with eclipse, and comfortable with Make files, you might be able to create a build mechanism within eclipse using the command line Make files as examples. </p> http://forums.leaflabs.com/topic.php?id=270#post-2104 Thu, 28 Oct 2010 23:21:56 +0000 Silntknight 2104@http://forums.leaflabs.com/ <p>As far as I know, Eclipse is only really good for Java. The code the Maple IDE uses is very similar (IMO), but not quite the same. For things like <code>pinMode()</code> Eclipse will just throw errors at you, unless you configure them as <code>System.in</code> commands. Either way, it will be more work that using the Maple IDE, which is pretty good anyway. I guess I don't see why you would want to use Eclipse. </p> http://forums.leaflabs.com/topic.php?id=270#post-2096 Thu, 28 Oct 2010 15:16:40 +0000 snigelen 2096@http://forums.leaflabs.com/ <blockquote><p>2nd question is can the STM lib for FFT's be ported over to the maple? how much work would this be? just to get an idea...</p> </blockquote> <p>That shouldn't be hard to do, it's just number-crunching. I've done a quick test with the FFT (without going in to the details) and got some reasonable results.

Since the fft-stuff is written in assembler it will not work in the current version of Maple IDE (it will not compile (well assemble) it, it's just ignored). But it works if you use it with the stand alone stuff, with a Makefile (in Linux or Mac). </p> http://forums.leaflabs.com/topic.php?id=270#post-2095 Thu, 28 Oct 2010 12:47:17 +0000 anotherDJ 2095@http://forums.leaflabs.com/ <p>Hi,</p> <p>a few friends and I are planing on using the Maple for our 4th yr design project.
