Raspberry Pi 2.2 Inch GPIO display (without touch screen)
Description
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.
Feature
- Character number: 320x240
- Screen scale: 2.2'

Overview
Install Driver
Screen
- If it's the first time for you to use this LCD module , please download the device driver for Raspberry Pi ,you can download the file from the following link http://www.52pi.net/forum.php?mod=viewthread&tid=1363&highlight=rtc
- If you are done download the device driver ,copy and past them into 'pi' folder in Raspberry Pi
- type
sudo tar -jxpvf TFT-stable-Build-20150424.tar.bz2 -C
to extract the device driver file
- modify modules file in /etc folder ,you can type
sudo vim.tiny /etc/modules
to open this file.To modify the file you should follow the picture beside
fbtft dma
fbtft_device name=rpi-display rotate=270 speed=64000000 gpios=dc:24,reset:23,led:18

File:2.2TFT tech6.png
- If you have finished above step ,then ,reboot the Raspberry Pi,and now you will see the reboot details is on the screen
Keyboard
- It is easy to setup the keyboard,first you should install evtest to detect the keyboard
- modify modules file in /etc folder like following picture ,just add code
gpio_keys_device pulldown active_low=0 keys=26:103,21:108,20:105,16:106
File:2.2TFT tech4.png
File:2.2TFT tech8.png
File:2.2TFT tech9.png
- Then, reboot the system,type
sudo evtest
to initiate the program,type0
to set test mode.Then,you press buttom on Pi TFT Module,the test information will printed in the screen
