= I2C setup =
[[http://www.instructables.com/id/Raspberry-Pi-I2C-Python/|Instructables]]

I order to access smbus functions like 'i2c_smbus_read_byte_data' use package libi2c-dev (sudo apt-get install libi2c-dev)

Specify the i2c bit-rate by adding the following two lines to '/boot/config.txt':
 *dtparam=i2c1=on 
 *dtparam=i2c_arm_baudrate=xxx

= RaspberryPi 3 onboard WiFi =
To completely disable the onboard WiFi from the firmware on the Pi3, add
dtoverlay=pi3-disable-wifi
in /boot/config.txt
