Preface

The Raspberry Pi is now a well known initial development board which can be used for IOT（Internet of things), Robert control, Pilotless driving, Voice assistant, Identify Recognization and such staffs. But the command line is unfriendly for Desktop dwellers, hum? Today we are going to build a Ras-Pi PC step by step which may make you feel kind. It is simple and explicit which can even be implemented by a pupil and will be the first step of your developer's journey

1. Prepare the Materials：

• Raspberry Pi 2B/3B/3A+/3B+/Zero/Zero W/Zero WH(Do not have one yet? Get one now!)
• 8GB or bigger micro memory card(8GB class 4 is recommended)&Card reader
• 10.1 inch 1200x1920 HDMI IPS LCD Display&Hdmi Cable
• ·Mouse&Keyboard -just ones handy for you
• An adapter of 5V&over2A
• ·USB Micro power supply
• A laptop or another computer to program the memory card

2.Prepare the System Images and Tools

1)choose one image

Here are many kinds of images for Raspberry-Pi over the world, you need to choose one with a visual desktop. In today's project, the official image of Rasbian is recommended.

2)Download your image and then unzip the file.img.

3)Burn it to your SD card. Here arer many tools can complete this work. And Win32diskimager is recommended. Here is a terse tutorial:

• Plug in the USB thumbdrive or SD or microSD card to your computer. It should be detected and appear as a drive in Windows.
• Open Win32 Disk Imager, choose the.img or image file you want to write as Image File and choose the USB or SD drive as Device and press Write.

• The write may take a while. Once it is done, remove the USB thumbdrive or SD card and insert it into your Raspberry Pi.

3.Configure the screen

Now you have already burned your SD Card, and to make sure that the 10.1-inch screen can work well on your device, we need to modify some files.

When you plug your Card into your computer, you can find a partition called boot. Then find config.txt in it.

Add the corresponding initialization parameter configuration code of the screen at the bottom of the configuration file(Notpad++ will be a good tool for developers, I suggest you to have one):

    force_trubo=1
    gpu_freq=300
    core_freq=400
    hdmi_pixel_freq_limit=400000000
    hdmi_drive=2
    hdmi_mode=87
    disable_overscan=1
    # 10.1 inch
    hdmi_timings=1200 0 100 24 52 1920 0 65 4 25 0 0 0 60 0 169000000 0
    max_framebuffer_width=1920
    max_framebuffer_height=1920
    display_rotate=3
    framebuffer_width=1920
    framebuffer_height=1200

Finally, plug all your staff: 10.1 inch Screen(HDMI), Mouse and keyboard, Power up your PI.

Congratulation! your first Ras-PC is finished.

Enjoy！

Subsequent Work

To make your Ras-PC more productive and friendly, here is a list of application you may need. You can use :

sudo apt-get install (package name)

to install them. If the package is not found, run following command first.

    sudo apt-get update    sudo apt- get upgrade

In this progress you may need username and password, and here is the default client of Raspberry Pi:

    username:pi    password:Raspberry

Sometimes you may need to add the source links. Let's take Chrome-the most popular explorer over the world, for example:

run following command first

echo "deb http://dl.google.com/linux/chrome/deb/ stable main" | sudo tee /etc/apt/sources.list.d/google-chrome.list

then run

    sudo apt-get update

finally, run

    sudo dpkg -i google-chrome-stable_current_amd64.deb

or

    sudo apt-get -y install google-chrome-beta

List of Productivity Applications

Synapse | Kate | Geany | AutoKey | LibreOffice | Chrome | Pidgin | Skype | Google Hangouts

List of Music, Photos, and Video Applications

VLC | digiKam and Shotwell | GIMP | Clementine | Spotify

List Utility Applications

Dropbox | Deluge | CrashPlan | PeaZip | Wine | VirtualBox | Terminator

And to become an advanced developer, there are different types of sensors to build your IOT networks, and to make the port more friendly you may need Grove Base Hat for Raspberry Pi .
