== Github ==<br />
* https://github.com/Edragon/RPI<br />
* https://github.com/Edragon/RPI_Display<br />
== Setup == <br />
* raspi-config -> sudo raspi-config -> Interfacing Options -> SPI -> Yes<br />
=== Packages ===<br />
Install BCM2835<br />
wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.59.tar.gz<br />
tar zxvf bcm2835-1.59.tar.gz<br />
cd bcm2835-1.59<br />
./configure<br />
make<br />
sudo make check<br />
sudo make install<br />
Install WiringPi<br />
cd<br />
git clone git://git.drogon.net/wiringPi<br />
cd ~/wiringPi<br />
git pull origin<br />
./build<br />
Python2<br />
sudo apt-get update<br />
sudo apt-get install python-pip<br />
sudo apt-get install python-pil<br />
sudo apt-get install python-numpy<br />
sudo pip install RPi.GPIO<br />
Python3<br />
sudo apt-get update<br />
sudo apt-get install python3-pip<br />
sudo apt-get install python3-pil<br />
sudo apt-get install python3-numpy<br />
sudo pip3 install RPi.GPIO<br />

<br />
If you do not have GIT installed, then under any of the Debian releases (e.g. Raspbian), you can install it with:<br />
<br />
sudo apt-get install git-core<br />
If you get any errors here, make sure your Pi is up to date with the latest versions of Raspbian:<br />
<br />
sudo apt-get update<br />
sudo apt-get upgrade<br />
To obtain WiringPi using GIT:<br />
<br />
git clone git://git.drogon.net/wiringPi<br />
If you have already used the clone operation for the first time, then<br />
<br />
cd wiringPi<br />
git pull origin<br />
Will fetch an updated version then you can re-run the build script below.<br />
<br />
To build/install there is a new simplified script:<br />
<br />
cd wiringPi<br />
./build<br />
The new build script will compile and install it all for you – it does use the sudo command at one point, so you may wish to inspect the script before running it.<br />
<br />
== Hardware Config ==<br />
* Turn on SPI, IIC option is raspi-config -> advanced option<br />
<br />
== Reference ==<br />
* Adafruit python library https://github.com/adafruit/Adafruit-Raspberry-Pi-Python-Code.git<br />
* python GPIO module wiki explanation http://sourceforge.net/p/raspberry-gpio-python/wiki/Examples/<br />
=== Common used commands and program ===<br />

|-<br />
| cp || copy file or directory || cp -r CharLCD /home/pi (copy folder CharLCD to directly /home/pi, -r to keep construe of the folder)<br />
