HMC5883L on RaspberryPI(2)

TurnToJPG -->

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/ 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/

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

	root@rasp:~/code/i2c# tree -d
