2012-02-12, version 0.8

  • Patches for version 1.0 of the Arduino IDE. Older versions might still work, but I’ve not tested it.
  • A change to the build process: rather than link all the system objects directly into the executable, bundle them in a library first. This should make the final executable smaller.
  • If TARGET isn’t explicitly set, default to the current directory name. Thanks to Daniele Vergini for this patch.
  • Add support for .c files in system libraries: Dirk-Willem van Gulik and Evan Goldenberg both reported this and provided patches in the same spirit.
  • Added a size target as suggested by Alex Satrapa.

Unreleased, version 0.7

  • Added -lm to the linker options, and -F to stty.

2011-06-23, version 0.6

  • Added ard-parse-boards. Mark Sproul suggested doing something like this ages ago, but I’ve only recently looked at it in detail.
  • Fabien Le Lez reported that one needs to link with -lc to avoid linker errors.

2011-06-23, version 0.5

  • Imported changes from Debian/Ubuntu, which incorporate a patch from Stefan Tomanek so that libraries would be compiled too.

Note: Many other people sent me similar patches, but I didn't get around to using them. In the end, I took the patch from Debian and Ubuntu: there seems merit in not forking the code and using a tested version. So, thanks and apologies to Nick Andrew, Leandro Coletto Biazon, Thibaud Chupin, Craig Hollabaugh, Johannes H. Jensen, Fabien Le Lez, Craig Leres, and Mark Sproul.

2010-05-24, version 0.4

Tweaked rules for the reset target on Philip Hands’ advice.

2010-05-21, version 0.3

  • Tidied up the licensing, making it clear that it’s released under LGPL 2.1.
  • Philip Hands sent me some code to reset the Arduino by dropping DTR for 100ms, and I added it.
  • Tweaked the Makefile to handle version 0018 of the Arduino software which now includes main.cpp. Accordingly we don’t need to—and indeed must not—add main.cxx to the .pde sketch file. The paths seem to have changed a bit too.
