Raspberry Pi Presentation

I am making the post available here, but it has formatting issues. Please view the original post on my website HERE: http://jasonraimondi.com/blog/raspberry-pi/

Perhaps I wrote too much for this... Huge Huge updated posts for the final project are coming Monday Night or tuesday!! But for now... I am going to bed. See you in 5 hours :)

Nope not that. Raspberry Pi

How to start using your Raspberry Pi

  Some items that you are going to need initially -Micro USB for power -SD card (larger than 2GB) to run the OS -HDMI or RCA cable for Video   Since all that comes with the Raspberry Pi is the computer without an operating system, the first thing you are going to need to do to get your Raspberry Pi operational is download an operating system for the Raspberry Pi to install on your SD Card. The first OS you should probably start with is called Raspbian. It is available for download via torrent or html here: http://www.raspberrypi.org/downloads Once you download the OS you are going to need to unzip the file to get the iso of the OS. Follow this guide for mounting your OS: http://elinux.org/RPi_Easy_SD_Card_Setup   Now for the initial boot. If everything goes according to plan, you should see the Raspi-config screen [caption id="attachment_279" align="alignnone" width="899"] Raspi-Config[/caption] This gives you a few initial setup options to configure.

• expand_root - Expand the install to fill the entire SD card (if there is extra room available)
• overscan - Configure the overscan of the picture on your monitor or television
• change_pass - change the password for the user 'pi' (default user is 'pi' and password is 'raspberry'
• overclock - over clock the raspberry pi from 700mHz to 1000mHz and it doesn't void the warranty
• ssh - enable ssh access to the Raspberry Pi via terminal
• boot_behavior - default is to boot to terminal, you can enable auto boot to desktop
• update - definitely update always, make sure you are connected to the internet

When you finish, it will put you back to the terminal. To access your desktop type 'startx' Explore around.It looks like Windows wrapped in a new UI. Raspbian is based off KDE, KDE is a UI variation of linux that has a very similar look, but much more elegant in my opinion, than windows. You can install programs via the LXTerminal on your desktop. To download the Arduino IDE the code is: sudo apt-get install ardunio To get the chromium web browser (open source Chrome), the command is sudo apt-get install chromium   Here are a few links for new users to Raspbian and Linux http://www.raspberrypi.org/phpBB3/viewtopic.php?f=26&t=4751 http://www.raspberrypi.org/phpBB3/viewtopic.php?f=66&t=15123   Elinux.org has great beginner guides for the Raspberry Pi http://elinux.org/R-Pi_Hub#Beginners_Guide   Adafruit has made a really great web interactive developer environment that you can install on your raspberry pi. It was made for people to learn how to program Python. http://learn.adafruit.com/webide/installation   If you want to remote desktop to your Raspberry Pi, you will want to check out Raspberry Pi VNC Server. This will let you control your Raspberry Pi's desktop through your computer. http://elinux.org/RPi_VNC_Server" title="http://elinux.org/RPi_VNC_Server   Cambridge University released a course on building a Raspberry Pi operating system online for free. The course is available here: http://www.cl.cam.ac.uk/freshers/raspberrypi/tutorials/os/ The course is called "Baking Pi" and it is meant to help incoming freshmen get familiar with basic computer science before starting school, but it is available for everyone. A brief introduction to the course: Throughout the course, you are learning to write in assembly code. Assembly code is very close to what the computer actually understands, what it actually understands is Binary Code. Assembly code is a translation of binary into human readable text. Binary Code --> Assembly Code --> Programming Code --> Application --> User When programming normally, the programmer writes code in languages such as C++, C#, Java, and Python, and then a program called the compiler translates what the programmer wrote into assembly code, which is then later translated into binary.

The vessel will be battery powered and only run the bare essentials needed for navigation. The Raspberry Pi will run the Electronic Speed Controller that manages the Motor and rutter, taking GPS positioning information for navigation. The vehicle will take photographs and or video during its mission.   Stepper Motor Raspberry pi http://www.reddit.com/r/raspberry_pi/comments/ybe4n/driving_a_stepper_motor_using_a_pi_and_python/ http://www.pololu.com/catalog/product/1182 Driving a stepper motor using raspberry pi and python What is it for?

All of the on board processing is handled by the Raspberry Pi. "This initially seems rather counter intuitive, as time sliced operating systems like Linux are not as predictable in their execution time as a simple real-time microcontroller program, but I've found in practice preemption allows the main control loop to run at a very reliable frequency."

• Runs an SSH interface to your laptop via a wireless adapter.
• Log data to the on board SD card
• Potential for complex route mapping and real-time integration into Google Maps

Raspberry Pi & Arduino

Why would you need an arduino then if you have a raspberry pi? Well the microprocessor in the arduino makes it great for quick processes and on the fly tasks. It is good for very quick, but somewhat basic calculations in real time. The raspberry pi is capable of doing on the fly tasks, the has the extra task of having to process the whole Operating system through the chip, and can get laggy quickly.
