Example Arduino sketch packaged as Python package.

# blink #

This project demonstrates how an Arduino sketch may be distributed as a Python package.

## Programming sketch using arduino_helpers and avr_helpers ##

Although not strict dependencies of the blink package, by using [arduino_helpers][1] and [avr_helpers][2], we can easily flash the compiled .hex firmware files included in the blink package.

For example:

>>> import blink
>>> board = 'diecimila'
>>> firmware = blink.get_firmwares()[board][0]
>>> firmware.name
path('blink.hex')
>>> from arduino_helpers.context import ArduinoContext, Board, Uploader
>>> # For Ubuntu systems, Arduino IDE is installed at `/usr/share/arduino`.
>>> context = ArduinoContext('/usr/share/arduino')
>>> uploader = Uploader(Board(context, board))
>>> from avr_helpers import AvrDude
>>> # Automatically select port, by iterating through available serial
>>> # ports until a connection can be established.
>>> avr_dude = AvrDude(uploader.protocol, uploader.board_context.mcu, uploader.speed)
>>> stdout, stderr = avr_dude.flash(firmware, ['-D'])
>>> print stderr
