Fixed in this in <a href="http://github.com/leaflabs/maple-ide/commit/119edd46a245ff544698c2b0166a0361c494ff28" rel="nofollow">http://github.com/leaflabs/maple-ide/commit/119edd46a245ff544698c2b0166a0361c494ff28</a> ; you can copy those changes directly into your ./hardware/leaflabs/boards.txt</p> <p>#3: Yes, the timers increased library size significantly. libmaple is definitely large and in charge at this point, there isn't much room in RAM for usercode. Currently we are prioritizing a stable API and finishing feature and library implementation before we do any size or performance optimization; there should be large trivial losses in compile size with some simple tweaks. If size is an issue and you'd like to jump in an shake out some redundant branching ./libmaple/timers.c is where to start! Disabling the MAPLE_DEBUG flag also saves a couple KB by getting rid of the ASSERT() statements, though we think they are useful to the user. </p> http://forums.leaflabs.com/topic.php?id=107#post-606 Fri, 23 Jul 2010 09:31:15 +0000 leaflabsandy 606@http://forums.leaflabs.com/ <p>The Arduino 328P only gave up 2K flash out of 32K for overhead. (6.6% of total flash)<br /> The Maple ARM loss is 128K - 61K (from above) 67K for overhead?
