Introduction To The Beagleboard

2. What is Beagle Bone Black..?
 It is a low-cost, development platform for
developers.
 Boot Linux in under 10 seconds and get
started on development in less than 5 minutes
with just a single USB cable.

4. Nuts & Bolts

5. Beagle Board Means
• Bring your own peripherals
• Entry-level cost ($149/179)
• ARM Cortex-A8 (superscalar)
• Graphics and DSP accelerated
• Linux and open source community
• Environment for innovators

6. Hardware
Processor: AM335x 1GHz ARM® Cortex-A8
• 512MB DD3 RAM
• 2GB 8-bit eMMC on-board flash storage
• 3D graphics accelerator
Connectivity
• USB client for power and communications
• USB host
• Ethernet
• HDMI
• 2x46 pin headers
Software Compatibility

7. History
• It has two versions 1)BEAGLE BOARD
2)BEAGLE BOARD XM
• Feb 2008: Rev A concept demonstrated at meeting with key
kernel maintainers and open source developers at TIDC
• Jun 2008: Rev B launched broad availability with Digit-Key.
• May 2009: Rev C doubles RAM to 256MB
• Jan 2010: Rev C4 bumps performance to 720MHz and resolves
USB power supply stability issue.

8. Beagle Board -XM
• A modified version of the Beagle Board called the Beagle Board-XM
started shipping on August 27, 2010.
• It measures in at 82.55 by 82.55 mm and has a faster CPU core
(clocked at 1 GHz compared to the 720 MHz of the Beagle Board).
• RAM (512 MB compared to 256 MB), onboard Ethernet and 4 port
USB hub.
• It has micro SD card.
• The addition of the Camera port to the -XM provides a simple way
of importing videos.

10. Browsing Your Beagle Board
• Firstly, just test that the
connection is active by trying
to connect to the BBB with a
browser.
• Connect to the URL
http://192.168.7.2
• You should see a helpful
introductory web page
served by the Beagle Board
itself

11. • On Linux or Mac simply open a terminal window and
type the following command:
ssh 192.168.7.2 –l root

15. Why Beagle Board XM To Be Used
 In beagle board there is no over voltage
protection circuit.
 It is having only one USB, no insertion of
memory card, camera header, various
expansions.
 It is having only 256mb of memory as
compare to the beagle board XM.

16. LED Blinking: Wiring +ve To Pin 10 &
-ve To GND

17. LED blinking: writing the program
Back to the Linux/Mac prompt and create the executable
file
Program:
…and execute it
# nano blink.py
import Adafruit_BBIO.GPIO as GPIO
import time
GPIO.setup("P8_10", GPIO.OUT)
while True:
GPIO.output("P8_10", GPIO.HIGH)
time.sleep(0.5)
GPIO.output("P8_10", GPIO.LOW)
time.sleep(0.5)
# python blink.py

23. Differences

24. It is perfect for physical computing and smaller
embedded applications.
It can be complemented with cape plug-in boards.
Capes are expansion boards which can be stacked
onto the beagle bone board (up to four at one time).

26. Exiting Applications
 Interfacing to all of your robotics motor drivers.
location or pressure sensors.
 2D or 3D cameras.
 Running Open CV, Open NI and other image collection.
 Analysis software to recognize the objects around your
robot and the gestures you might make to control it.
