Smaller C: Lean Code for Small Machines

For makers looking to use the smallest microcontrollers or to wring the highest performance out of larger ones, the C language is still the best option. This practical book provides a solid grounding in C basics for anyone who tinkers with programming microcontrollers. You’ll explore the many ways C enables developers and makers to get big results out of tiny devices.

Author Marc Loy shows you how to write clean, maintainable C code from scratch. This language and its cousin, C++, are still widely used to write low-level code for device drivers or operating systems. By understanding C syntax and its quirks, you’ll gain an enduring computer language literacy that will help you pick up new languages and styles more easily.
