OOBE w/RasPI
Goal: Just wanted to hook this thing up to power and ethernet and ssh into it. That’s all.
Tried to d/l and install
http://www.raspberrypi.org/downloads Downloaded Debian Image
Using:
Image Writer for Windows
https://launchpad.net/win32-image-writer/+download
Must manually extract. No self-installer.. Put in C:\win32-image-writer\
Unzippeded archlinux-hf-2013-01-22.zip Write archlinux-hf-2013-01-22.img to an SD card
Booted, then discovered it had no ssh out of the box. *sigh*
Did a little actual reading and discovered it archlinux-hf doesn’t ship with ssh enabled See http://www.penguintutor.com/linux/raspberrypi-headless
Looked at the Adafruit RasPi Distro – http://learn.adafruit.com/adafruit-raspberry-pi-educational-linux-distro/occidentalis-v0-dot-2
D/L’d unzipped and wrote to SD card. Power-cycled pi. Comes up. Will ask for a DHCP address on your ethernet
How to ssh onto your Pi
Some people like the putty ssh client. Others like me like poderosa. The simplest approach I find is to use the ssh that comes w/Git for Windows. Just install it then run Git Bash command line tool
How to discover the IP address allocation
You can go to your DHCP server, which is typically your gateway router and try to find it..
Or… *if* you have itunes installed you also have a magical bonjour service installed which allows for auto-discovery..
So at the command prompt you can type

And *BAM* you are in.
Plug In Bar Code Reader
I wanted to mess with a bar code reader..
My generic $39 bar code scanner from amazon http://goo.gl/uRZXl
Do a tail -f /var/log/messages then plug in the scanner. You should see:
[ 2685.578555] snd_bcm2835_playback_close:167 Alsa close [ 2834.526579] usb 1-1.2: new low speed USB device number 4 using dwc_otg [ 2834.631871] usb 1-1.2: New USB device found, idVendor=05fe, idProduct=1010 [ 2834.631908] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 2834.631930] usb 1-1.2: Product: WIT 122-UFS V2.02 [ 2834.631945] usb 1-1.2: Manufacturer: WIT Electron Company [ 2834.649637] input: WIT Electron Company WIT 122-UFS V2.02 as /devices/platform/bcm2708_usb/usb1/1-1/1-1.2/1-1.2:1.0/input/input0 [ 2834.649784] generic-usb 0003:05FE:1010.0001: input: USB HID v1.10 Keyboard [WIT Electron Company WIT 122-UFS V2.02] on usb-bcm2708_usb-1.2/input0
Take note of the input0, Now go into /dev/input and you should see an event0 entry.
pi@raspberrypi /dev/input $ ls /dev/input ./ ../ by-id/ by-path/ event0 mice
Now it is just a matter of writing a little python script:
[cc lang=”python” width=370]
print “barcode scanner tests”
def k():
byte = []
f = open(‘/dev/input/event0’, ‘r’)
while True:
for bit in f.read(1):
byte.append(ord(bit))
if len(byte) == 8:
print byte
byte = [
[/cc]
Installing The Adafruit Web IDE
Then I went ahead and kept following the Adafruit instructions – http://learn.adafruit.com/webide/installation
pi@raspberrypi:~$ curl https://raw.github.com/adafruit/Adafruit-WebIDE/alpha/scripts/install.sh | sudo sh
