C Programming for Arduino

Overview of this book

Physical computing allows us to build interactive physical systems by using software & hardware in order to sense and respond to the real world. C Programming for Arduino will show you how to harness powerful capabilities like sensing, feedbacks, programming and even wiring and developing your own autonomous systems. C Programming for Arduino contains everything you need to directly start wiring and coding your own electronic project. You'll learn C and how to code several types of firmware for your Arduino, and then move on to design small typical systems to understand how handling buttons, leds, LCD, network modules and much more. After running through C/C++ for the Arduino, you'll learn how to control your software by using real buttons and distance sensors and even discover how you can use your Arduino with the Processing framework so that they work in unison. Advanced coverage includes using Wi-Fi networks and batteries to make your Arduino-based hardware more mobile and flexible without wires. If you want to learn how to build your own electronic devices with powerful open-source technology, then this book is for you.

Approaching calculation optimization

This section is an approach. It means it doesn't contain all the advanced tips and tricks for programming optimizations, but contains the optimizations on pure calculation.

Generally, we design an idea, code a program, and then optimize it. It works fine for huge programs. For smaller ones, we can optimize while coding.


Normally, our firmware is small and so I'd suggest that you consider this as a new rule: Write each statement keeping optimization in mind.

I could add something else right now: Don't kill the readability of your code with too many cryptic optimization solutions; I thought of pointers while writing that. I'll add a few lines about them in order to make you familiar with, at least, the concept.

The power of the bit shift operation

If I consider an array to store things, I almost always choose the size as a power of two. Why? Because the compiler, instead of performing the array indexing by using a CPU-intensive multiply operation, can use...
