Bare Metal C

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     Simple GPIO programming (blink an LED)     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     File and raw I/O     Floating-point numbers     Modular programming
