If you’re interested in making the plunge from Arduino (etc.) to directly working with an MCU, you’ll inevitably have to learn some basic C. There are a number of books that can teach you the basics, but if you’re looking for a refresher on one specific topic or keyword, “The C Book” is a great (and surprisingly thorough) online resource. Have another suggestion for people interested in getting start in C? Feel free to leave a suggestion in the comments!

Just do it. Learn C. It’s good for your soul… or something like that. 🙂
The C programming Language
By Brian W. Kernighan and Dennis M. Ritchie.
Published by Prentice-Hall in 1988
ISBN 0-13-110362-8 (paperback)
This is one I would also recommend.
I found this the other day in a bench writeup,
Introduction to Algorithms, Second Edition
Thomas H. Cormen
Charles E. Leiserson
Ronald L. Rivest
There are probably newer editions but these are what I read. 😉
Sorry to spam, I nearly forgot, the best investment I have ever made in a book, was 7.99 on this …. I thought it was 9.99 (get the print edition it is out of hand useful when your starting out)
C Pocket Reference
Peter Prinz, Ulla Kirch-Prinz
C Pocket Reference is indeed good for a quick reference … the entire “Pocket” series from O’Reilly is generally very good (C++, C#, SQL, Regular Expressions, etc.)
Odd – my comment didn’t post. Here it is again and apologies if it’s a duplicate.
The only book I’ve used in the past 25 years or so is the K&R book titled “The C Programming Language”. It’s the gold standard reference on the subject and you’ll learn things about the language that you’ll never see in an online tutorial.
Most people don’t refer to it by it’s title, in my experience – they just call it “The K&R Book”.
If you check out the copyright/disclaimer notice in the webpage….
“The publication of the online version is for historical interest and readers are warned that it should be treated as an historical document. There is now a later standard for the C programming language and this publication cannot be considered current: whilst for the most part the current and the first standard are very close, some substantive changes and extensions have occurred since 1991. NO WARRANTY IS OFFERED AS TO THE COMPLETENESS OR ACCURACY OF THE MATERIAL.”
There are several revisions to the ‘C’ standard, although the latest revision (C99) has seen very poor adoption rates for a number of reasons and many people still prefer C89 to C99 (see ANSI C on Wikipedia). The documentation is obviously aiming at C89 but this covers the vast majority of embedded development in C and there is still a great deal of extremely helpful information in the linked manual.
