I have the following display "High PPI 2.2 inch TFT Display shield for Raspberry pi 2B/B+ With 6 Keyboards and Remote IR" (built in in case): Some pictures and instructions can be found here.

So once connected it just white and not shows anything. I tried to follow these instructions/steps:

  1. Download the official firmware, then upgrade to the latest kernel sudo rpi-update

  2. Installation gpio libraries and drivers:

sudo apt-get install gcc python-pygame python-dev

sudo wget https://pypi.python.org/packages/source/R/RPi.GPIO/RPi.GPIO-0.5.11.tar.gz

sudo tar zxvf RPi.GPIO-0.5.11.tar.gz

cd RPi.GPIO-0.5.11

sudo python setup.py install

  1. Config file to enable I2C and SPI Interface sudo nano /boot/config.txt

Add the following line: dtparam=i2c_arm=on, spi=on

  1. Config modules to startup screen.

sudo nano /etc/modules

Add the following line: fbtft_device name=pitft rotate=270 speed=48000000 fps=30

  1. Config cmdline file to display the console;

sudo nano /boot/cmdline.txt

Add the following line before “rootwait”

fbcon=map:10 fbcon=font:VGA8x8

  1. Save then restart;

But it still does not work. Any advice what I'm missing? Easiest way to make it work?

I was able to find easy and detailed steps for installing software required to make it work at Adafruit site.

Steps are the following (easy option):

  1. Download and install kernel and helper script:

    curl -SLs https://apt.adafruit.com/add-pin | sudo bash
    sudo apt-get install raspberrypi-bootloader
    sudo apt-get install adafruit-pitft-helper

  2. Run helper script:

    sudo adafruit-pitft-helper -t 22

  3. Reboot by issuing sudo reboot

Note: It seems that there is no way to make this TFT work simultaneously with external monitor connected over HDMI.
