About the Raspberry Pi

The Raspberry Pi is a low cost, credit-card sized computer that plugs into a

computer monitor or TV, and uses a standard keyboard and mouse. It is a

capable little device that enables people of all ages to explore computing, and

to learn how to program in languages like Scratch and Python. It’s capable of

doing everything you’d expect a desktop computer to do, from browsing the

internet and playing high-definition video, to making spreadsheets,

word-processing, and playing games.

What’s more, the Raspberry Pi has the ability to interact with the outside world,

and has been used in a wide array of digital maker projects, from music

machines and parent detectors to weather stations and tweeting birdhouses

with infra-red cameras. We want to see the Raspberry Pi being used by kids all

over the world to learn to program and understand how computers work.

Raspberry Pi Pin Numbering Introduction

There are three methods for numbering Raspberry Pi’s GPIO:

1. Numbering according to the physical location of the pins, from left to right,

top to bottom, the left is odd, the right is even.

2. Numbering according the GPIO registers of BCM2835/2836 SOC.

3. Numbering according the GPIO library wiringPi.

Raspberry Pi GPIO Library Introduction

Currently, there are two major GPIO libraries for Raspberry Pi, RPi.GPIO and

wiringPi.

RPi.GPIO:

RPi.GPIO is a python module to control Raspberry Pi GPIO channels. For more

information about RPi.GPIO, please visit:

https://pypi.python.org/pypi/RPi.GPIO/

For examples and documentation, please visit:

http://sourceforge.net/p/raspberry-gpio-python/wiki/Home/

The RPi.GPIO module is pre-installed in the official Raspbian operating system,

you can use it directly.

wiringPi:

The wiringPi is a GPIO access library written in C for the BCM2835/6 SOC used

in the Raspberry Pi. It’s released under the GNU LGPLv3 license and is usable

from C and C++ and many other languages with suitable wrappers. It’s

designed to be familiar to people who have used the Arduino “wiring” system.

For more information about wiringPi, please visit : http://wiringpi.com/

Install wiringPi:

Step 1 : Get the source code

$ git clone git://git.drogon.net/wiringPi

Step 2 : Compile and install

$ cd wiringPi

$ git pull origin

$ sudo ./build

Press Enter, the script “build” will automatically compile wiringPi source code

and then install it to the Raspberry Pi.

Next, verify whether the wiringPi is installed successfully or not:

wiringPi includes a command-line utility gpio which can be used to program

and setup the GPIO pins. You can use this to read and write the pins and even

use it to control them from shell scripts.

You can verify whether the wiringPi is installed successfully or not by the

following commands:

$ sudo gpio -v

$ sudo gpio readall

If you can see the information shown above, it indicates that the wiringPi has

been installed successfully.

How to use the wiringPi and the RPi.GPIO

Here we take a blinking LED for example to illustrate how to use the wiringPi C

library and the RPi.GPIO Python module.

Step 1 : Build the circuit according to the following schematic diagram

Note : Resistance=220Ω

For Python user:

Step 2 : Create a file named led.py

$ sudo touch led.py

Step 3 : Open the file led.py with vim or nano

$ sudo vim led.py

Write down the following source code, then save and exit.
