Have you heard of the Raspberry Pi? Maybe you have, maybe you haven’t. Either way I have and I think they are rather cool device. I have a set of instructions that I like to go through in order to get my devices up and running.

First Boot

After you get your machine up and running, you will see raspiconfig come up. Make sure you enable the sshd service and expand the image to consume all the space on the flash drive.

Then reboot the device.

Second Boot

Adding Erlang

I am a fan of Erlang, so I like to install the latest and greatest version from Erlang Solutions.

sudo nano /etc/apt/sources.list

Then add the following line:

deb http://binaries.erlang-solutions.com/debian wheezy contrib

Once that is done:

wget -O - http://binaries.erlang-solutions.com/debian/erlang_solutions.asc | sudo apt-key add -

Enabling I2C and SPI

If you would like to communicate with other ICs, then you will probably need to use either I2C or SPI, so lets enable them right off the bat.

sudo nano /etc/modprobe.d/raspi-blacklist.conf

While you are in there, you should make the file look like:

#blacklist spi-bcm2708
#blacklist i2c-bcm2708

Then edit the available modules:

sudo nano /etc/modules

And make them look like:

snd-bcm2835
i2c-dev

You’ll need to add your user account to a group to use i2c devices.

sudo adduser pi i2c

Updating and Install Software

Now for the fun and/or boring part.

sudo apt-get update && sudo apt-get -yq dist-upgrade && sudo apt-get -yq install git-core build-essential i2c-tools python-smbus

If you want to install Erlang:

sudo apt-get install -yq esl-erlang

Of course you can add any other packages to the list depending on what you want to do.

Reboot!

To make sure everything is okay, especially the new devices/modules, you should reboot the system.

sudo reboot
