Exploring Raspberry Pi: Interfacing to the Real World with Embedded Linux (英语) 平装 – 2016年6月13日
"...this is a book worth having on your shelf." (I programmer, August 2016)
DR. DEREK MOLLOY is a senior lecturer at the School of Electronic Engineering, Faculty of Engineering and Computing, Dublin City University, Ireland. He is also the author of the hugely popular book on the BeagleBone platform titled Exploring BeagleBone, also published by Wiley. His popular YouTube video series has introduced millions of people to embedded Linux and digital electronics topics. He has received several awards for teaching and learning, including the 2012 Irish Learning Technology Association (ILTA) national award for Innovation in Teaching and Learning. The same year, he was also awarded the Dublin City University President's Award for Excellence in Teaching and Learning.

The Kindle edition's a disappointment. Here's why.
1. The book has a great table of contents with a 3 level outline; chapters, sub headings under each chapter and sub topics under each sub heading. The Kindle edition only has a 2 level outline, no sub topics, making it extremely cumbersome, if not useless, as a navigation tool.
2. The Kindle edition left out the index. Really, no index, and no, the global word search is not the same as a good index created and edited by a professional indexer.
So minimal table of contents and no index makes the Kindle edition pretty useless as a convenient reference. If you don't believe me, try to find the topic section on Transistors using the Kindle edition. I'm sure you can eventually, but it's a PITA.
By the way, I think it's sad that my one star review brings down the rating of the paper edition. Amazon, I should be able to review the Kindle edition separately from the paper edition. Especially if they are substantially different.
The book starts from basics - Raspberry Pi hardware, basic Linux commands, basic circuits for interfacing, etc. He then gets into the depths of how to interface all of these together. I'm fortunate to have enough background in these areas to weave through this, but those with less of a computer or electronics background might want to have a local geek or two handy to call in for help when needed. He has excellent coding examples in multiple languages, builds from simple to more complex examples, and provides libraries to continue your own programming projects using the knowledge you have gained throughout the book.
I'm an Electrical / Computer Engineer by trade, and I've had an interest in introducing hobby electronics to my kids. When I first saw the Raspberry Pi, I thought this might be the ideal platform on which to develop that. This book is the missing piece to that puzzle for me. It's exactly what I was hoping for, with all the details one could want about making this magnificent little board talk to other devices. I picture many blinking lights and beeping speakers in the months to come as a result of this book! I consider this a bargain-priced book for everything that's contained within it. If there's something you want to connect up to a Raspberry Pi, odds are, there's a solution somewhere in this book. I highly recommend it.
To make this review much shorter - if you want to do projects with the RPi, buy this book. It explains things about how the RPi works in great detail, gives tons of examples of sample circuits, and shows the math as well for calculating current drain and voltage drops for most of the circuits, so you're not just plugging things in blindly. It is full of practical advice on how to wire things up so you do things properly and don't blow up your Pi (like "use an optocoupler if you have an external power supply connected to the load").
Further, it has an extensive section on programming the Pi, showing programs at a variety of complexity levels and running times to turn the GPIO pins on and off (which is what we most care about when programming the Pi).
