HMC5883L on RaspberryPI(2)

Here are some explanation on the code in “HMC5883L on RaspberryPI”.
The i2clibraries calls the “quick2wire” library.

	root@rasp:~/code/i2c/pythoncode# grep "quick2wire" ./ -r
	./i2clibraries/i2c.py:from quick2wire.i2c import I2CMaster, writing_bytes, reading
	Binary file ./i2clibraries/__pycache__/i2c.cpython-32.pyc matches
	Binary file ./i2clibraries/i2c.pyc matches

So we have to include QUICK2WIRE_API_HOME into the PYTHONPATH:

	export QUICK2WIRE_API_HOME=~/code/i2c/quick2wire-python-api/
	export PYTHONPATH=$PYTHONPATH:$QUICK2WIRE_API_HOME

So notice you have to specify the correct directory which contains the corresponding code.

	root@rasp:~/code/i2c# tree -d
	.
	├── pythoncode
	│   └── i2clibraries
	│       └── __pycache__
	└── quick2wire-python-api
