• Monitor and control several electronic devices with one of the best embedded computers

Who This Book Is For

If you are a developer with some hardware or electrical engineering experience who wants to learn how to use embedded machine-learning capabilities and get access to a GNU/Linux device driver to collect data from a peripheral or to control a device, this is the book for you.

What You Will Learn

• Set up and install a Debian operating system for your BeagleBone Black
• Get access to the serial console to manage the BeagleBone Black's bootloader and kernel
• Discover the pros and cons of native versus cross-compiling C applications
• Compile the Linux kernel from scratch and add custom device drivers
• Ascertain how a system daemon works and how high-level languages can interact with it
• Work with electronic components to build a small circuit
• Develop applications that interact with your circuits connected with the system's GPIOs, serial/USB ports, and I²C/SPI/1-Wire busses
• Use RFID LF readers, temperature sensors, barcode readers, ADC/DAC, and other peripherals to monitor and control your surroundings

In Detail

The BeagleBone Black is an embedded system that is able to run complete GNU/Linux distributions such as Debian or Ubuntu. Having powerful distribution capabilities, and packed with an easily expandable embedded board, the BeagleBone Black is a device that will allow users to build powerful and versatile monitoring and controlling systems.

You start off by learning how to set up the board from scratch; you will be introduced to the concepts of compilation and cross-compilation of user-space and kernel-space applications with some basic debugging techniques. Next, you will move on to high-level programming by using scripting languages; you'll then learn how to get access to different kinds of peripherals such as serial ports, USB devices, I2C/SPI, and 1-Wire. Finally, you will discover how to use or develop system daemons in several programming languages, collect peripheral data, and control a device. Accessing all peripherals and writing good monitoring and controlling programs can be a complex task; it's all too easy to make mistakes early in development that lead to serious problems in production. This guide is an invaluable tutorial if you are planning to use a BeagleBone Black to control or monitor projects.
