Preparatory work:

1. A 2G or more SD card, preferably a high-speed card, recommended CLASS4 more than the card, because the card speed directly affect the speed of the Raspberry Pi.

2. Download the Raspberry Pi system image file at the following address:

https://www.raspberrypi.org/downloads/

Here are a number of operating system images for Raspberry Pi, choose one that suits you.

The Tools USB Image tool for installing the image under 3.WinXP and Win7 can also be found on the above page.

USB Image Tool

Installation Combat:

1. Unzip the downloaded operating system image compressed file and get the IMG image file.

2. Connect the SD card holder or reader to the computer.

3. Unzip and run the USB Image tool.

4. Select the System Image (img file) in the software, select "Restore", then select the appropriate system image img file, and then confirm.

5. The installation process may be slow, depending on the speed of your SD card.

Wait until the dialog box 100% appears to indicate success.  Posted in Raspberry Pi | Post Recovery Raspberry Pi 2/b+ Portable Suite Upgrade Tutorial: Using keystrokes to simulate keyboard/mouse/joystick use posted on December 9, 2015

1. Assemble the package, start the system and follow the previous tutorial to configure the screen

2.SSH Login to the Raspberry Pi, install the relevant Python libraries and software

$sudo apt-get Update
$sudo Apt-get Install Libudev-dev
$sudo Apt-get Install Python-pip
$sudo pip Install Rpi.gpio
$sudo pip Install Python-uinput

3. Register the Uinput module (you can also add this line to the/etc/modules, automatically register the module after the boot)

$sudo modprobe Uinput

4. Unzip the attachment program and copy it to the Raspberry Pi (Python-keys)

5. Run the simulation keyboard or joystick program and press the key to see the effect

$sudo python rpi-2.2tft-kbrd.py

Or

$sudo python rpi-2.2tft-jstk.py

Or

$sudo python rpi-2.2tft-mouse.py

Note: Uinput's key value is generally uinput. Key_xx (XX is the key, such as the letter A, is uinput. KEY_A)

Python-uinput Library can be used for reference (HTTPS://GITHUB.COM/TUOMASJJRASANEN/PYTHON-UINPUT)
Reference to the use of the Rpi.gpio Library (http://pypi.python.org/pypi/RPi.GPIO/)
