Bare Metal C teaches you to program embedded systems with the C
programming language. You'll learn how embedded programs interact with
bare hardware directly, go behind the scenes with the compiler and
linker, and learn C features that are important for programming regular
computers.
Bare Metal C will teach you how to program embedded devices with the C
programming language. For embedded system programmers who want precise
and complete control over the system they are using, this book pulls
back the curtain on what the compiler is doing for you so that you can
see all the details of what's happening with your program.
The first part of the book teaches C basics with the aid of a low-cost,
widely available bare metal system (the Nucleo Arm evaluation system),
which gives you all the tools needed to perform basic embedded
programming. As you progress through the book you'll learn how to
integrate serial input/output (I/O) and interrupts into your programs.
You'll also learn what the C compiler and linker do behind the scenes,
so that you'll be better able to write more efficient programs that
maximize limited memory. Finally, you'll learn how to use more complex,
memory hungry C features like dynamic memory, file I/O, and
floating-point numbers.
Topic coverage includes:
The basic program creation process

Writing serial device drivers
The C linker and preprocessor
Decision and control statements
Numbers, arrays, pointers, strings, and complex data types
Local variables and procedures
Dynamic memory
