Rapid BeagleBoard Prototyping with MATLAB and Simulink

Overview of this book

As an open source embedded single-board computer with many standard interfaces, Beagleboard is ideal for building embedded audio/video systems to realize your practical ideas. The challenge is how to design and implement a good digital processing algorithm on Beagleboard quickly and easily without intensive low-level coding. Rapid BeagleBoard Prototyping with MATLAB and Simulink is a practical, hands-on guide providing you with a number of clear, step-by-step exercises which will help you take advantage of the power of Beagleboard and give you a good grounding in rapid prototyping techniques for your audio/video applications. Rapid BeagleBoard Prototyping with MATLAB and Simulink looks at rapid prototyping and how to apply these techniques to your audio/video applications with Beagleboard quickly and painlessly without intensive manual low-level coding. It will take you through a number of clear, practical recipes that will help you to take advantage of both the Beagleboard hardware platform and Matlab/Simulink signal processing. We will also take a look at building S-function blocks that work as hardware drivers and interfaces for Matlab/Simulink. This gives you more freedom to explore the full range of advantages provided by Beagleboard. By the end of this book, you will have a clear idea about Beagleboard and Matlab/Simulink rapid prototyping as well as how to develop voice recognition systems, motion detection systems with I/O access, and serial communication for your own applications such as a smart home.

Video input: Digital camera hardware connection


There are two general ways to connect a digital camera to the BeagleBoard: the simple USB interface, and the camera connector. The latter connector was designed to be used with camera modules from Leopard Imaging (https://www.leopardimaging.com). However, in this chapter we will follow the first USB approach, using a USB-based web camera which is easy to obtain online. A list of supported USB cameras has been provided at http://www.ideasonboard.org/uvc. The Logitech C310 has been employed for this book (around $30 from Amazon).

Another advantage of the USB camera is easy connection. After you get the Logitech C310, you can simply open the package and insert the USB interface into the BeagleBoard. An example of physical connection has been provided in the following figure:
