Here's what you'll need to do for the class. Unless stated otherwise these are individual exercises, not team.

I'm updating this from last year, so be sure to check the year to be sure it's been refreshed. If the background is white, it hasn't been updated.

'''All assignments are due the start of the following week. Initially that is a Thursday!'''

== Week 1 ==

| 1-1
| 30-Aug-2012
|
| Introductions, Demos
| Fire up your Beagle and see it work. Do everything in Exercise 09. Due Friday.
'''[[EBC Exercise 01 Start Here]]''' gives an overview of what we'll be doing over the next few days. Start setting up your Linux development computer now. You can do either a native install, or a virtual machine. [[EBC Exercise 06 Notes on VirtualBox | Here]] and [[EBC Exercise 07 Notes on Installing Ubuntu in VMware Player | here]] are some notes in virtual machine installs. They are out of date. Feel free to update them.

I suggest Ubuntu 12.04 LTS. Some of the TI software may require it. I may not be able to help with other versions of distributions.
