The Raspberry Pi has traditionally been programmed using Python. Although this is a very
powerful language many programmers may not be familiar with it. C on the other hand is perhaps
the most commonly used programming language and all embedded microcontrollers can be programmed
using it. The C language is taught in most technical colleges and universities and almost all
engineering students are familiar with using it with their projects. This book is about using
the Raspberry Pi with C to develop a range of hardware-based projects. Two of the most popular
C libraries wiringPi and pigpio are used. The book starts with an introduction to C and most
students and newcomers will find this chapter invaluable. Many projects are provided in the
book including using Wi-Fi and Bluetooth to establish communication with smartphones. Many
sensor and hardware-based projects are included. Both wiringPi and pigpio libraries are used in
all projects. Complete program listings are given with full explanations. All projects have
been fully tested and work. The following hardware-based projects are provided in the book:
Using sensors Using LCDs I²C and SPI buses Serial communication Multitasking External and timer
interrupts Using Wi-Fi Webservers Communicating with smartphones Using Bluetooth Sending data
to the cloud Program listings of all Raspberry Pi projects developed in this book are available
on the Elektor website. Readers can download and use these programs in their projects.
Alternatively they can customize them to suit their applications.
