I bought a Raspberry Pi Model B+ back in December. I didn't have a monitor to plug it into so it just kind of sat idle for a while.
I recently picked up a new monitor so I've been tinkering with the Raspberry Pi and I wanted to capture all of my setup and configuration.
Don't bother with “Noobs”
I just went ahead and installed Raspbian rather than boot with Noobs and ultimately end up installing Raspbian anyway. Download it here.
Find the SD card
I'm using a Mac to write the image.
Get a list of all the disks:
Identify the disk representing the SD card and unmount it. In my case it is /dev/disk2:
diskutil unmountDisk /dev/disk2
Write the image to the SD card
dd tool to write the image to the SD card:
sudo dd bs=1M if=2015-02-16-raspbian-wheezy.img of=/dev/disk2
dd doesn't show any output unless there is an error or the process is finished. To see the progress, you can open up another terminal and send SIGUSR1 to the process:
or, you can just press
<ctrl>-T in the same terminal where
dd is running.
Boot the Pi!
Once the image has been written to the SD card, eject the card:
sudo diskutil eject /dev/disk1
Put it into the Raspberry Pi and turn it on. When it finishes booting, it will automatically run
raspi-config. Go through the menus and set things up as you like. Be sure to enable SSHd for secure remote terminal sessions.
Update existing packages and install some useful software
Be sure to update the installed packages:
sudo apt-get update && sudo apt-get upgrade
Since I'm running on a Mac, I like to have Appletalk and Bonjour installed:
sudo apt-get install netatalk
I'm really liking Node.js lately, so I plan on writing code using that. The version in
apt-get is severely out-of-date, so here's an alternative way to install it:
wget http://node-arm.herokuapp.com/node_latest_armhf.deb sudo dpkg -i node_latest_armhf.deb
Once it is installed, you check which version was installed like so:
Another good thing to have is wiringPi which is a C library for access the GPIO pins. It also includes a command line utility,
gpio, for manipulating the GPIO pins:
git clone git://git.drogon.net/wiringPi pushd wiringPi ./build
Once it is installed, test it out:
gpio -v gpio readall

That's it for now.
