Raspberry PI 2.8 TFT Add-on is customized for Raspberry Pi based on 2.8 TFT LCD display module. The screen is driven based on an 8-bit data bus and a 4-bit ILI9323DS to control bus interface, which can display 263K colors. Module controls contents to be displayed via GPIO on Raspberry Pi. With touch function, it can be used to display the desktop of Raspberry Pi and realize clicking, touch and feedback.
Using together with FBTFT and touch driver developed by Norto, users can make 2.8 TFT Add-on as a mini display in Linux system. Please visit this site to get more information about FBTFT: https://github.com/notro/fbtft
Iteaduino Plus is an ARM development board based on Allwinner A20. In theory, Iteaduino Plus supports 2.8 TFT add-on display in the circumstance of enough GPIO interfaces. Thus, we will show you how to transplant 2.8 TFT add-on drivers into Iteaduino Plus to enlarge its applying scope.
In this blog, we will tell you how to install Raspberry PI 2.8 TFT Add-on on Iteaduino Plus A20, then let a picture showed on Raspberry PI 2.8 TFT Add-on. More application case, please click the previous blog: Raspberry Pi 2.8 TFT Add-on Touch Function Realizing.
1.Preparation
- Iteaduino Plus A20 ( with iteados-A20-debian-xfce-2.0.4-2014-05-13.img and good network)
- Raspberry PI 2.8 TFT Add-on
- Foca
- Mini USB
- Raspberry Pi adapter cable
- 2.0mm male header
2.Assembly Picture
3.Get the Install Package
wget http://itead.me/ITEADDownload/software/fbtft-v0.1.deb
4.Install Diver
sudo dpkg –i fbtft-v0.1.deb
When the installation finished, there is a fb2 node automatically emerged in the directory /dev/
5.Test and Start xface
FRAMEBUFFER=/dev/fb2 startx
At this moment, you can see the familiar xface interface on the display. Just like the assembly picture.
6.FBTFT Using Guide
Please refer to this blog: http://blog.iteadstudio.com/raspberry-pi-2-8-tft-add-on/. When you type the same commands, you can make the same function realized. For instance, make the display showing a picture.
sudo apt-get install fbi
wget http://imall.iteadstudio.com/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/i/m/im120525010_8_1.jpg
sudo fbi -d /dev/fb2 -T 1 -noverbose -a im120525010_8_1.jpg
Attention: In RASPBIAN, the node is fb1 when driver installation finished; while in ITEAD OS, the node emerged is fb2. That’s the small difference between them.
