PTH's embedded Raspberrypi tools and tweaks

I2C

Enable I2C support by configuring the interface with raspi-config and do a reboot to load the kernel drivers.

Check if the kernel drivers were loaded at startup:

lsmod | grep i2c

For a Raspi 3B the result should look something like this:

i2c_bcm2835            16384  0
i2c_dev                20480  0

Then, install the following packages to do some basic i2c tinkering:

sudo aptitude install i2c-tools
