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.

IR sensor hardware


In the previous chapters, we focused the discussion on developing the environment and process for the BeagleBoard. However, for some applications, a single BeagleBoard is not enough, which means we usually need several external devices to work with the BeagleBoard to operate as a whole system. Usually we name an external device as sensor, if it mainly provides the information of the real-life world. Accordingly, we will name an external device as actuator, if it can affect the real-life world. Nonetheless, we will need a driver to power the external devices and obtain information from these external devices for the BeagleBoard as input to the processing algorithm.

Note

A driver is a segment of code, which can be called in the form of lib or source code. These code will enable the user to access the internal and external hardware devices. In most scenarios the hardware vendor will provide you with the driver, but in some cases, you will have to write the driver code following...
