70.36.235.234: Picture had the destination extraction directory, but the code snippet didn't. Thanks!

=Raspberry Pi 2.2 Inch GPIO display (without touch screen)=
==Description==
This product is End Of Life.
The PI-TFT22A module features a 2.2'display with 320x240 16-bit color pixels. This PI-TFT22A module refresh it's screen rapidly because the TFT module communicates with raspberry Pi in a high speed SPI interface ,this PI-TFT22A module can be used as Xwindow port ,displaying images or video etc. it plugs right in on top of your Model A+, B+ or Pi 2 and fits as HAT.

You can download configuration-free image or configurable packages, adjustable brightnes [level 0 -255], HAT compatible and Onboard buttons, you can load kernel modules to support GPIO KeyBoard function, almost all GPIO available on this board [non SPI 0,GPIO 18,GPIO 24,GPIO23],Very easily be other uses, IDROM has built initialization data to support Device Tree boot.

2.Setup it up by editing /etc/modules file as following steps: 
<code>sudo vim.tiny /etc/modules</code> 
<code>fbtft dma</code> 
<code>fbtft_device name=rpi-display rotate=270 speed=64000000 gpios=dc:24,reset:23,led:18
</code> 
There are some pictures showing how to set it up.

===Keyboard===
*It is easy to setup the keyboard,first you should install a software called "evtest" to detect the keyboard. 
0. Install the package evtest: 
<code>sudo apt-get -y install evtest </code> 
1. Add following parameters to /etc/modules file. 
<code>gpio_keys_device pulldown active_low=0 keys=26:103,21:108,20:105,16:106</code>
