Or suggest another Maple-compatible toolchain?</p> <p>As to the question why I started with libmaple, you have to know that my expectation of what a device library should be, is heavily influenced by avr-libc. Take interrupts, for example. avr-libc gives me easy macros and a well-written documentation on how to create my own interrupt handlers. libmaple, on the other side, "secretly" implements a few interrupt handlers just in case somebody might need a millis() function. I am happy to cherry-pick some parts of libmaple, but I don't want a good part of my processor/memory busy without me knowing. </p> http://forums.leaflabs.com/topic.php?id=2136#post-11738 Sat, 14 Jul 2012 19:58:22 +0000 robodude666 11738@http://forums.leaflabs.com/ <p>Hey,</p> <p>If you open up the Makefile, you'll see this section:</p> <pre><code># Official libraries: LIBMAPLE_MODULES += $(SRCROOT)/libraries/Servo LIBMAPLE_MODULES += $(SRCROOT)/libraries/LiquidCrystal LIBMAPLE_MODULES += $(SRCROOT)/libraries/Wire # Experimental libraries: LIBMAPLE_MODULES += $(SRCROOT)/libraries/FreeRTOS</code></pre> <p>This includes some of the libraries, which you probably don't need. You can comment them out, by placing a # in front of each line you don't want included. For example, to not compile the FreeRTOS library:</p> <pre><code># Official libraries: LIBMAPLE_MODULES += $(SRCROOT)/libraries/Servo LIBMAPLE_MODULES += $(SRCROOT)/libraries/LiquidCrystal LIBMAPLE_MODULES += $(SRCROOT)/libraries/Wire # Experimental libraries: #LIBMAPLE_MODULES += $(SRCROOT)/libraries/FreeRTOS</code></pre> <p>Right above that there's also:</p> <pre><code>LIBMAPLE_MODULES += $(SRCROOT)/wirish</code></pre> <p>Which includes all of the C++ wirish support. You can elect to not include it if you only plan to use libmaple.</p> <p>That's about it... You can remove libmaple if you want, but then why are you using libmaple to begin with?</p> <p>-robodude666 </p> http://forums.leaflabs.com/topic.php?id=2136#post-11737 Sat, 14 Jul 2012 15:23:18 +0000 mh555 11737@http://forums.leaflabs.com/ <p>Hi!</p> <p>When it comes to microcontrollers, I am a kind of "control freak". I don't like hundreds of things working simultaneously without me knowing. I was horrified to see how much gets compiled for a simple blinking of a LED, resulting in a codesize of more than 14 kB!</p> <p>I want to start with the bare metal and then add a few things, but only those that I need and understand.</p> <p>Unfortunately, I have almost no experiences with setting up toolchains, so I was not successful with modifying the supplied Makefile to get rid of all libmaple and wiring and still keep the linker happy.</p> <p>Could anyone help me here with a minimal Makefile? </p>
