 When I first started planning for this course I was told "The hardest things about designing such a course is deciding what to leave out".  That is very true.  There is a huge range of topics that could be covered. They seem to fall in four broad categories:

+When I first started planning for this course I was told "The hardest things about designing such a course is deciding what to leave out".  That is very true.  There is a huge range of topics that could be covered. They seem to fall in four broad categories:
 # Traditional embedded topics such as reading switches and flashing LEDs (general purpose I/O), UARTS, I2C, SPI, and A to D's.
 # Embedded Linux topics such as tools for code development and what happens when the kernel boots up, how to write device drivers, etc.
 # Advanced applications.  This includes open source projects such as processing streaming media with [http://gstreamer.freedesktop.org/ GStreamer] and computer vision with [http://opencv.willowgarage.com/wiki/ OpenCV]
 Here's what I have so far. Everything before the Kernel topics are run completely on the BeagleBoard.  No need to set up a host computer.

 The following exercises start the transition to Linux based approaches.  They introduce Linux-based tools, but we're not working with the kernel yet.

 : As the exercises get more involved it become important to use some revision control software.  '''git''' is a distributed revision control system with an emphasis on being fast. It was initially designed and developed by Linus Torvalds for Linux kernel development. This exercise shows how to setup git on both the host computer and the Beagle and takes you through some of the basic commands.

 : In the previous exercise you saw how to bring audio into the Beagle and send it out again. You also did some processing on the audio. All this was done on the ARM processor. The DM3730 on the BeagleBoard has both an ARM processor and a C64x fixed-point DSP. This exercise shows you how to use the DSP via C6Run. C6Run is a set of tools which will take in C files and generate either an ARM executable, or an ARM library which will leverage the DSP to execute the C code.

-Here are a few additional topics I have covered in the past, or plan to cover next time.
-* '''Audio I/O'''.  I give an example of how to capture audio from the line in and send it to line out.
-* '''Display Sub System''' (DSS).  The DSS on the OMAP supports 3 frame buffers, one for graphics and 2 for video.  I give them the c code needed to pull a frame of video from a web cam via [http://www.exploits.org/v4l Video 4 Linux] (v4l2) and store it in a file.  I also give the code to take the frame from the file and put it in a video frame buffer.  Their task is to combine the two programs to pull live video from the camera and display it on the monitor.
-* '''DSP'''.  Next time I plan to have my students use the DSP via '''c6run''' ([[ECE497 Lab13 Using the DSP via c6run]]).  c6run is a slick system that runs code on the DSP via the ARM without having to know all the details of how the two interact.  I plan to give details of how memory is shared between the two processors (ARM with virtual memory and the DSP without) and show how [http://processors.wiki.ti.com/index.php/CMEM_Overview cmem] manages it.
-* '''OpenCV'''.  There is a port of the Open Computer Vision Library [http://opencv.willowgarage.com/wiki/ openCV].  I plan a one day overview of it with some demos.
-* '''GStreamer'''.  There is also a port of [http://gstreamer.freedesktop.org/ GStreamer], the open Multimedia Framework. It even has a plugin that uses the DSP.
-* '''Speech Recognition'''.  TI has an [https://gforge.ti.com/gf/project/tiesr/ embedded speech recognizer] that has been ported to the Beagle.  I'll present it and suggest projects that might use it.
-I'll present other topics based on what the class is interested in.
+There are many open source projects that run on the Beagle and could make a good starting point for a class project.  Here are some.
