sudo apt-get install libusb-1.0-0-dev

2. Refresh system

$ sudo apt-get update
$ sudo apt-get upgrade

Installed OpenCV dependency package

$ sudo apt-get install build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
$ sudo apt-get install python3.5-dev python3-numpy libtbb2 libtbb-dev

Download OpenCV 2.4.13 source code

https://opencv.org/releases/

Untar source code and below example we assume file path /opt/opencv but user should follow user's environment path.

$ cd opencv
$ mkdir release
$ cd release
$ mkdir my_build_dir
$ cd my_build_dir

/opt/opencv is example path, user should follow user's environment path.

$ cmake -D BUILD_TIFF=ON -D WITH_CUDA=OFF -D ENABLE_AVX=OFF -D WITH_OPENGL=OFF -D WITH_OPENCL=OFF -D WITH_IPP=OFF -D WITH_TBB=ON -D BUILD_TBB=ON -D WITH_EIGEN=OFF -D WITH_V4L=OFF -D WITH_VTK=OFF -D BUILD_TESTS=OFF -D BUILD_PERF_TESTS=OFF -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH=/opt/opencv_contrib/modules /opt/opencv/

$ make -j4
$ make install

Check OpenCV version

$ pkg-config --modversion opencv

=== EPD Application === ==== Xml file Configure ==== Before image display ,user have to configure xml of file path、file name、 slide_interval and waveform mode. Content of xml file as below. <epd_config><epd name="EPD 31.2"></epd></epd_config>

-=== EPD Application ===
-==== Xml file Configure ====
-Before image display ,user have to configure xml of file path、file name、 slide_interval and waveform mode. Content of xml file as below.
-  <?xml version="1.0"?>
-  <epd_config>
-    <epd name="EPD 31.2">
-        <color>KW</color>	    <!--KW/COLOR -->
-        <image_path>D:\application\photoImg\</image_path>
-        <image_name>
-          <full_update>
-              <img>1.bmp</img>
-          </full_update>
-          <stop>stop</stop>
-        </image_name>
-        <slide_interval>0</slide_interval>
-        <en_set_temperature>0</en_set_temperature> <!-- Enable:1, Disable:0 -->
-        <temperature>25</temperature>
-        <waveform_mode>2</waveform_mode>
-        <rotate>180</rotate>
-  </epd>
-  </epd_config>
-'''&lt;image path&gt;&nbsp;: ''' User should assign photo image path in operating system , application search image file under this path.
-'''&lt;img&gt;&nbsp;:''' User have to write the image name in xml file and application follow path and name to load image file. It can be assigned more than one &lt;img&gt; tag name between &lt;full_update&gt; and &lt;/full_update&gt; then following &lt;img&gt; tag to load image and display in sequence. It's only support '''Bmp''' and '''jpg''' type.
-'''&lt;stop&gt;''' Stop tag use to load image at once. Above mention stop tag in xml, application terminated after 1.bmp update done. In carousel mode stop tag must removed from xml.
-'''&lt;slide_interval&gt;:''' Slide interval is delay time in second between every image display.
-'''&lt;set_temperature&gt;''' user don't need configure temperature.
-'''&lt;waveform_mode&gt;''' Waveform mode usually choose mode 2 for image update. waveform explicit detail see [[EPD-320_application_tech#Waveform_mode|Section 1.4 waveform mode]]
-'''&lt;rotate&gt;''' There has 4 options 0 、90、180、270 of angle
-==== Execution ====
-User should check all information of xml is correct before execute application or it may cause error happened.
-. Open command line
-. Change current directory to EPD_4TCON
-. Execute command EPD_4TCON with parameter xml file name
-Windows&nbsp;: '''"EPD_4Tcon.exe setting.xml"'''
-Linux&nbsp;: $'''./EPD_4Tcon setting.xml'''
-[[File:Epd320 6 1.jpg|500px|execute EPD4tcon]]
-== Quick start ==
-Following step to achieve different play mode.
-=== Single display ===
-This example showing how to configure xml for image display once on linux ubuntu 16.04.
-Step 1: Image path depends on user's defined. we defined path that is in /usr/local/photoImg in this example.
-Step 2: we assume one picture that name is 1.bmp to display , we should put 1.bmp in image path and put img tag in xml.
-  <?xml version="1.0"?>
-  <epd_config>
-    <epd name="EPD 31.2">
-        <color>KW</color>	    <!--KW/COLOR -->
-        <image_path>/usr/local/photoImg</image_path>
-        <image_name>
-          <full_update>
-              <img>1.bmp</img>
-          </full_update>
-          <stop>stop</stop>
-        </image_name>
-        <slide_interval>0</slide_interval>
-        <en_set_temperature>0</en_set_temperature>
-        <temperature>25</temperature>
-        <waveform_mode>3</waveform_mode>
-        <rotate>180</rotate>
-  </epd>
-  </epd_config>
-Step 3: $'''./EPD_4Tcon setting.xml'''
-This application will stop after updating content of 1.bmp
-=== Carousel mode ===
-Carousel mode is non-stop application except system signal , user could stop running procedure by SIGINT ,SIGKILL signal.
-Below example is xml format in carousel mode that three images display in sequence every 10 seconds intervals .
-Step 1: Image path depends on user's defined. we defined path that is in /usr/local/photoImg in this example.
-Step 2: There are three images to display , we should put 1.bmp，2.bmp，3.bmp in image path and put img tag in xml.
-Step 3: Removed tag of &lt;stop&gt;.
-Step 4: We defined every 10 seconds to change image and writing 10 at tag of &lt;slide_interval&gt;
- <?xml version="1.0"?>
-  <epd_config>
-    <epd name="EPD 31.2">
-        <color>KW</color>	    <!--KW/COLOR -->

-        <image_name>
-          <full_update>

-In mode 0 ,it is used to completely clear the display when initial panel then using white image to display panel instead of mode 0. It prevents panel from damaging.
-In mode 1 Du mode non-flashy waveform but it easily appear Ghosting on panel. it is suitable highlight text.
-[[File:213JPG.jpg|400px|partial update]]
-In mode 2it userd for 16 level grayscale images. When panel is wide temperature Range(-20 ~ 70 °C), it only support mode 0、1、2 not support mode 3、4、5
-In mode 3 it's same with mode 2 but mode 3 has high quality image appearance.
-In mode 4 it is used for fast switching or simple animation only the conversion between black and white, sacrificing the image quality and afterimage effect for fast response time.
-'''mode 4 (A2)scenario'''
-[[File:Epd130 14.jpg|800px|partial update]]
-In mode 5 it's used for text turn to page when text is arranged on the same horizontal on next page .
