The BeagleBone Black being an embedded Linux development board can be an excellent choice for building various measurement and control systems by developers and hobbyists. This book is thought as a highly practical guide which can help readers to design measurement and control systems driven by the BeagleBone Black. These systems can comprise external electronic circuits controlled by programs written in Python. Since many measurement systems process analog signals, the guide contains a brief theory and practical applications dedicated to use of popular high-resolution analog-to-digital converters. The guide covers processing small signals with instrumentation amplifiers and measuring frequencies of digital signals using high-precision PWM-To-Voltage converters.
The material of the book also covers digital signal synthesis with digital potentiometers and digital-to-analog converters. The readers will find practical designs of digitally programmable wide-band oscillators, signal amplifiers and PWM circuits. The guide describes practical aspects of interfacing and programming high-precision wide-band sinusoidal and rectangular waveform generators using a popular high-resolution Direct Digital Synthesizer AD9850.
A few projects are dedicated to designing network and distributed systems using the BeagleBone Black and Tiva C Series Connected LaunchPad. The guide also covers interfacing the BeagleBone Black with popular Arduino Uno and Arduino Due boards. A few measurement and control systems with Arduino boards are presented as well.
The BeagleBone Black can be easily fitted into wireless systems using the Wixel Programmable USB Wireless modules from Pololu Corp., so the readers can explore a couple of projects presented in this guide. A few projects illustrate using a Bluetooth protocol in simple wireless systems built around the BeagleBone Black, desktop PC and Arduino Due.
Each project is accompanied by a brief description which helps to make things clear. Most projects described in the book can be improved or modified if necessary. Each project includes a circuit diagram accompanied by the Python source code. The projects with Arduino Uno and Arduino Due also include the source code written in the Processing language. All projects were designed and tested on the BeaglBone Black Rev.C running Debian Linux.
