To Install wiringPi library (Required for some applications/demos)

=====================================================================

• Connect your raspberry Pi up to the Internet and download WiringPi library from github:

  cd

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

  cd wiringPi

  ./build

• This will then download and install the wiringPi library, assuming you have git installed on your Raspberry Pi already.

• If you encounter an error such as: error while loading shared libraries: libgeniePi.so: cannot open shared object file: No such file or directory do the following:

  sudo ldconfig -v

This should solve the problem

• Please see here for more detail if you need to install git also (https://projects.drogon.net/raspberry-pi/wiringpi/download-and-install/)

Disable Linux from using the Pi Serial Port so the GeniePi library can instead

=================================================================================

• From terminal, launch leafpad (or your chosen editor) with root:

  sudo leafpad

• Nagivate to /boot/cmdline.txt and remove the following text (LEAVE everything else intact)

  kgdboc=ttyAMA0,115200 console=tty1

• Save the file, overwriting the existing one.

• Navigate and edit /etc/inittab

• Comment out the bottom line by putting a '#' symbol at the start of it, where the bottom line is:

  T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100

• Save the file, overwriting the existing one
