Just what i was looking for,
This review is from: Raspberry Pi Assembly Language RASPBIAN Beginners: Hands On Guide (Paperback)
This was just the book I was looking for. Not only does it teach you how about programming the ARM chip it also delves into some of the specifics of the Raspberry Pi itself, and those topics you find unanswered in the forums. This book is worth it for that fact alone providing chapters on things like Thumb Code, Floating Point and programming the GPIO. This is all the advanced stuff in the final chapters of the book. The journey there in 260 pages is very enjoyable and although I am not a novice to programming in assembler the introductory chapters on using the GCC Assembler and Compiler where very instructive and what had looked at the onset to be a difficult tasks was in fact described in very easy terms. The programs as printed all worked with no issues and the text contained useful information on how to identify and locate issues when programs don't work as expected. Very useful.
Uniquely I think, the book also shows how you can take existing C programs written for the GCC compiler (and there are plenty around) and covert them into assembly language programs for the Raspberry Pi. I know nothing about C but that didn't stop me from `having a go' and this reverse engineering process was very interesting and I have been learning a lot from it. The book also covers how to use Raspbian Syscalls and the libc functions - with plenty of examples to play with.
I have a Gertboard attached to my Raspberry Pi, so the details about programming the GPIO port were very useful. I now understand how to use the GPIO registers and have no issues turning leds lights on and off via machine code.
In summary this is an excellent book which is a must-buy for anyone who wants to learn how to program their Raspberry Pi at the most fundamental level. Well priced and well written, and the print version I have is well-laid out and easy to follow.
