  23. #                          - support for uploading via ISP
  24. #                          - orthogonal choices of using the Arduino for
  25. #                            tools, libraries and uploading
  26. #

  30. #                            Arduino prior to upload
  31. #
  32. #         0.4  25.v.2010   M J Oldfield
  33. #                          - tweaked reset target on Philip Hands' advice
  34. #
  35. #         0.5  23.iii.2011 Stefan Tomanek
  36. #                          - added ad-hoc library building
  37. #              17.v.2011   M J Oldfield
  38. #                          - grabbed said version from Ubuntu
  39. #
  40. #         0.6  22.vi.2011  M J Oldfield
  41. #                          - added ard-parse-boards supports
  42. #                          - added -lc to linker opts,
  43. #                            on Fabien Le Lez's advice
  44. #
  45. #         0.7  12.vii.2011 M J Oldfield
  46. #                          - moved -lm to the end of linker opts,
  47. #                        to solve Frank Knopf's problem;
  48. #                          - added -F to stty opts: Craig Hollabaugh
  49. #                        reckons it's good for Ubuntu
  50. #
  51. #         0.8  12.ii.2012  M J Oldfield
  52. #                          - Patches for Arduino 1.0 IDE:

  54. #                              handle board 'variants';
  55. #                              tweaked compile flags.
  56. #                          - Build a library from all the system
  57. #                            supplied code rather than linking the .o
  58. #                            files directly.
  59. #                          - Let TARGET default to current directory
  60. #                as per Daniele Vergini's patch.
  61. #                          - Add support for .c files in system
  62. #                            libraries: Dirk-Willem van Gulik and Evan

  64. #                            provided patches in the same spirit.
  65. #
  66. #          0.9 26.iv.2012  M J Oldfield
  67. #                          - Allow the punter to specify boards.txt

  74. #                            Arduino serial port (Peplin's suggestion)
  75. #                          - Rejigged PATH calculations for general
  76. #                            tidiness (ex Peplin)
  77. #                          - Moved the reset target to Perl for
  78. #                            clarity and better error handling (ex
  79. #                            Daniele Vergini)
  80. #
  81. #          0.10 17.ix.12   M J Oldfield
  82. #            - Added installation notes for Fedora (ex Rickard Lindberg).

  95. # PATHS YOU NEED TO SET UP
  96. #
  97. # I've reworked the way paths to executables are constructed in this
  98. # version (0.9) of the Makefile.
  99. #
  100. # We need to worry about three different sorts of file:
  101. #
  102. # 1. Things which are included in this distribution e.g. ard-parse-boards
  103. #    => ARDMK_DIR
  104. #
  105. # 2. Things which are always in the Arduino distribution e.g.
  106. #    boards.txt, libraries, &c.
  107. #    => ARDUINO_DIR
  108. #
  109. # 3. Things which might be bundled with the Arduino distribution, but
  110. #    might come from the system. Most of the toolchain is like this:
  111. #    on Linux it's supplied by the system.
  112. #    => AVR_TOOLS_DIR
  113. #
  114. # Having set these three variables, we can work out the rest assuming
  115. # that things are canonically arranged beneath the directories defined
  116. # above.
  117. #
  118. # On the Mac you might want to set:
  119. #
  120. #   ARDUINO_DIR   = /Applications/Arduino.app/Contents/Resources/Java
  121. #   ARDMK_DIR     = /usr/local
  122. #
  123. # On Debian systems, you might prefer:
  124. #
  125. #   ARDUINO_DIR   = /usr/share/arduino
  126. #   ARDMK_DIR     = /usr
  127. #   AVR_TOOLS_DIR = /usr
  128. #
  129. # You can either set these up in the Makefile, or put them in your
  130. # environment e.g. in your .bashrc
  131. #
  132. # If you don't install the ard-... binaries to /usr/local/bin, but
  133. # instead copy them to e.g. /home/mjo/arduino.mk/bin then set
  134. #   ARDML_DIR = /home/mjo/arduino.mk

  138. # DEPENDENCIES
  139. #
  140. # The Perl programs need a couple of libraries:
  141. #    YAML
  142. #    Device::SerialPort
  143. #

  145. #
  146. # STANDARD ARDUINO WORKFLOW
  147. #
  148. # Given a normal sketch directory, all you need to do is to create
  149. # a small Makefile which defines a few things, and then includes this one.
  150. #
  151. # For example:
  152. #
  153. #       ARDUINO_LIBS = Ethernet Ethernet/utility SPI
  154. #       BOARD_TAG    = uno
  155. #       ARDUINO_PORT = /dev/cu.usb*
  156. #
  157. #       include /usr/share/arduino/Arduino.mk
  158. #
  159. # Hopefully these will be self-explanatory but in case they're not:
  160. #
  161. #    ARDUINO_LIBS - A list of any libraries used by the sketch (we
  162. #                   assume these are in
  163. #                   $(ARDUINO_DIR)/hardware/libraries
  164. #
  165. #    ARDUINO_PORT - The port where the Arduino can be found (only needed
  166. #                   when uploading
  167. #
  168. #    BOARD_TAG    - The ard-parse-boards tag for the board e.g. uno or mega
  169. #                   'make show_boards' shows a list
  170. #
  171. # Once this file has been created the typical workflow is just
  172. #
  173. #   $ make upload
  174. #
  175. # All of the object files are created in the build-cli subdirectory
  176. # All sources should be in the current directory and can include:
  177. #  - at most one .pde or .ino file which will be treated as C++ after
  178. #    the standard Arduino header and footer have been affixed.
  179. #  - any number of .c, .cpp, .s and .h files
  180. #
  181. # Included libraries are built in the build-cli/libs subdirectory.
  182. #
  183. # Besides make upload you can also
  184. #   make             - no upload
  185. #   make clean       - remove all our dependencies
  186. #   make depends     - update dependencies
  187. #   make reset       - reset the Arduino by tickling DTR on the serial port
  188. #   make raw_upload  - upload without first resetting
  189. #   make show_boards - list all the boards defined in boards.txt
  190. #   make monitor     - connect to the Arduino's serial port
  191. #
  192. ########################################################################
  193. #
  194. # SERIAL MONITOR
  195. #
  196. # The serial monitor just invokes the GNU screen program with suitable
  197. # options. For more information see screen (1) and search for
  198. # 'character special device'.
  199. #
  200. # The really useful thing to know is that ^A-k gets you out!
  201. #
  202. # The fairly useful thing to know is that you can bind another key to
  203. # escape too, by creating $HOME{.screenrc} containing e.g.
  204. #
  205. #    bindkey ^C kill
  206. #
  207. # If you want to change the baudrate, just set MONITOR_BAUDRATE. If you
  208. # don't set it, it defaults to 9600 baud.

  257. #     ISP_PORT     = /dev/ttyACM0
  258. #

  260. # read from boards.txt, based on the BOARD_TAG variable:
  261. #    
  262. #     ISP_LOCK_FUSE_PRE  = 0x3f
