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.

Voltage shifting


In detail, what we need to fix are two problems: one is how to power the ZMotion device, and the other is how to make them be able to talk to each other. There are many solutions to solve these problems; however, most of them will involve hardware assembling and require necessary electronic design experience.

Here, in this chapter, we are considering a ready-to-use solution, which is more suitable for users without an electronic background (for example, if you are from computer science). The trainer board from Tincan Co. Ltd. (http://www.tincantools.com/) has been designed to work with BeagleBoard-XM and includes a 1.8V to 3.3V bi-directional converting function. The selling price is only $59, which should be affordable for most users. We may also need to purchase another useful device—the breadboard—which is very helpful in rapid prototype development. A breadboard doesn't cost much, and is easily available at eBay, Amazon, or a local electronics shop.
