Linux platform is well equipped to the point even bash shell scripting can be used to do a decent hardware hacking control. I believe targeted audience is a weekend hacker and not serious C/C++ programmer. If that is a case, this books serves its target audience well.
There is only one thing that really bothers me.
Following a tradition of Raspberry Pi and Arduino , the first physical demonstration of the board is made on how to turn LED on.
Matt tells us to use 100 ohm resistor in series of LED. the GPIO pin is set up to source the current. With 3.3V output and 100 ohm resistor with LED Vf of about 1.8V, the resulting current will be around 15mA. This is OK for LED that is usually rated for 20 mA but appears to be way over the spec'ed source current of 4mA for this TI SOC. The setup does work (I did try it) and did not destroy my beaglebone but this is probably because the TI chip's design margin and not the GPIOs intended usage. Therefore I would not follow this if I were to use more than a single LED in the same fashion. Adafruit.com's tutorial (written by Simon Monk) recommends the use of 470 ohm resistor instead and warns against the use of lesser value resistor because "it could burn your beaglebone". Derek Molloy's youtube video even shows the set up where GPIO output is buffered by a small signal transistor to turn LED on. Needless to say, I am most comfortable with Derek's solution.
Other than this concern, the book succeeds in showing around the Beaglebone's vast playing ground. I liked the book for covering the broad spectrum of methods to enjoy this board in a relatively small number of pages.
I am not so novice (engineer that worked with Unix and Linux for years), but I still learned things I did not know.
But what's really great, is that it's fast... in very little time you can get started with linux, ssh, turn on LED's, Python scripts etc...
Withing 4 hours you learned all you need to get your internet controlled project started. I highly recommended it for the beginner, but also for the intermediate user.
Not to be fooled: this book is not a complete user manual, it just scratches the surface of all the potential of this Beablebone, but it's super fast to do, and touches many aspects of it (GPIO, PWM, Analog I/O, ethernet, python, JS, HDMI, cron, Cloud IDE).
If you want to get off to good start with open source devices buy the BeagleBone Black and get a copy of this book.
The BeagleBone Black is the latest addition to the series. It has a faster processor and a few more hardware capabilities. This book explains in detail how to configure the BeagleBone system, connect to outside networks and hardware, and write Python software that will exercise your project hardware. Once you have mastered this system, you can customize your design and even do remote testing. There is an appendix to show you how to extend your knowledge far beyond the material contained here if you want to take this experimenter package into a commercial enterprise.
I ordered the Kindle edition to make it easy to tap on a link and be connected directly to the extended information pages. This was a great convenience.
For my project needs I am going to build my project using C++ and this book is helping me find the libaries and development tools that I need to finish a professional project. The appendix shows how to develop code from OSX, Linux, and Windows platforms.
I am very pleased with this book's content and links.
Provides sample code for reader to work through for real outcomes.
Easy intro for newbies to micro controller use. Will probably be criticized for not being advanced enough for more complex project development by those in the know. Another 100 pages would be appreciated to dig a bit deeper. No doubt, you will have to find much more tutorial and reference materials as well as other books to go further.
Perfect intro for me in my quest to understand micro controller options and start-up difficulty.
