'''WiringPi''' is a set of C functions designed to make it easy for C and C++ programs to access the Raspberry Pi’s GPIO. There is also a utility program; gpio which you can use from the command-line to test simple '''GPIO''' operations.

The picture above shows the main board which provides access to the Pi’s main 8 GPIO pins, with the I2C and SPI connectors and serial pins. The I2C based analog (middle) and digital (bottom) expansion boards are below the mainboard. There are no SPI expansion boards at this time. (May, 2013)
The following pages will guide you through setting it up and programming it via the shell (BASH) and using wiringPi in simple C/C++ programs.

== Conclusion ==
Using the Quick2Wire boards with wiringPi should be fairly straightforward – there is nothing new in the Q2W boards that wiringPi can’t handle. The examples here are really just for guidance and hints…
