Arduino SCons (alternative)
An alternative way of building arduino sketches with SCons.
This project is designed to be:
- Flexible. Code generation? Multiple builds for different boards uploaded to the correct ports from one script? No problem.
- Easy to understand. No source munging. No automatic library detection. No magic.
This can either be installed system-wide, or per-project. Either way,
arduino.py should be installed into
$SITE_SCONS is one of the directories listed in the
SCons man page under
On Linux the following directories are appropriate:
$HOME/.scons/site_scons can be accomplished by running
This script does not do any munging of your source files, so you may need
reorder your functions (or add function prototypes), and add
#include <Arduino.h>. Your sketch should be in a
.cpp file, rather than an
A script to compile and upload a basic sketch might look something like this:
env = Environment(tools=["default", "arduino"]) env.ConfigureBoard("atmega328") core = env.ArduinoCore() sketch = env.Sketch("blink", ["blink.cpp", core]) env.Upload(sketch)
examples directory for more examples.
Installing the tool into an environment gives it the following methods:
This sets defaults for a whole bunch of environment variables (described
below), based on the board name. The supported boards and their settings can be

/usr/share/arduino is used.
