Lerning Objectives: Students should be able to

• describe the main functional units in a PC and be able to explain how they interact. They should know different bus types, and on this basis be able to account for different generations of PCs.

• explain what an operating system is and be able to explain important concepts such as multitasking, privilege levels and drivers.
• describe the main functional units of a microcontroller and be familiar with typical applications for a microcontroller. They should also have a basic understanding of how a microprocessor is built up and be able to explain concepts such as interrupts and interrupt handling both on a microcontroller and a microprocessor.
• solve simple instrumentation tasks using both PC and microcontroller. They should also master programming in C and LabVIEW on a level that enables them to solve such tasks.
• master basic troubleshooting of both software and hardware.

Although people say it is easy to make OpenCV 2.2 to work with MS Visual C++ 2010, but we did not get it to work properly while it seems that MS visual c++ 2008 works perfect with OpenCV 2.1. Here are the download links for both products :

OpenCV 2.1 : http://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.1/
This file is modified to work with MS Visual C++ 2008 and therefore there is no need to install CMake again.

MS Visual C++ 2008(Free of charge) : http://www.microsoft.com/downloads/en/details.aspx?familyid=a5c84275-3b97-4ab7-a40d-3802b2af5fc2&displaylang=en

Click More down here to read the rest of the tutorial …

1 – Installing OpenCV

After downloading OpenCV 2.1, you need to install the program. This is done by just running the EXE file which pops up the installation wizard. There you need to choose an installation path. I usually let it install to C:\OpenCV2.1. We refer to this path as ~ after this. DON’T FORGET to add the path for all users.

2- Installing MS Visual C++ 2008

After downloading MS VC++ 2008, you need to install the program. This is done by just running the installation wizard which downloads the necessary files.

3- Link OpenCV and VC++ together

Open VC++. Then navigate to Tools > Options > Projects and Solutions > VC++ Directories.

On “Show directories for, choose : Include Files

Add the following : “~\include\opencv”

On “Show directories for, choose : Library Files

Add the following : “~\lib”

Choose “Show directories for: Source Files

Add the following :

“~\src\cv”
“~\src\cvaux”
“~\src\cxcore”
“~\src\highgui”

Now we are done configuring VC++, but still we need some small changes in our project to be able to use OpenCV libraries

4- Project Configuration :

After creating the project, the OpenCV dependencies should be added.
Navigate to Open Project Properties: Project – %projectName% Properties
Open Linker Input properties: Configuration Properties > Linker > Input
Open the “…” window to edit “Additional Dependencies” and on each line put:

“cv210.lib”
“cxcore210.lib”
“highgui210.lib”

And any other lib file necessary for your project
Your project should now build. If you get any errors try restarting Visual Studio and then doing a clean Rebuild.

<pre>int relayPin = 02;
int addr = 128;

void eepThang() {
  eep_value = EEPROM.read(addr);
  if (eep_value == 1) {
    Serial.println("already reset. writing 0");
    EEPROM.write(addr, 0);
  }
  else {
    Serial.println("not reset.. writing 1, restarting");
    Serial.println(eep_value);
    EEPROM.write(addr, 1);
    Serial.println("done wrote... here we go");
    digitalWrite(relayPin, HIGH);
    delay(1000);
  }
}</pre>

The instruction to get Processing & Arduino talk together :

1. Download this file.
2. Unzip the library and copy the “arduino” folder into the “libraries” sub-folder of your Processing Sketchbook. (You can find the location of your Sketchbook by opening the Processing Preferences. If you haven’t made a “libraries” sub-folder, create one.)
3. Run Arduino, open the Examples > Firmata > StandardFirmata sketch, and upload it to the Arduino board.
4. Configure Processing for serial:http://processing.org/reference/libraries/serial/
5. In Processing, open one of the examples that comes with with the Arduino library(in the same folder that we just unzipped).
6. Edit the example code to select the correct serial port.
7. Run the example.

Path…/Library/Java/Extensions

This should be added as an external Jar file in properties of your project at Eclipse.

background color for your layout :
add the following code to your layout XML code(#ff32cf is the color code)

android:background="#ff23cf"

Background Image for your layout :
1- Add the image you want to the layout folder of your project.
2- Add the following code to your layout XML code

android:background="@drawable/bbg"

EditText features :
one of the features I want to talk about is android:singleLine which is very useful. If you want to get some info from the user, this text box is a good tool to use, but make sure you set the SingleLine variable to true. If not if they paste a 20 lines of text by mistake your whole GUI gets out of shape. Also if you want to use this for example to write an email text, then this should be set to false as you want it to contain several lines. The good thing about several lines EditText is that they do have scrolling function.

<EditText ... android:singleLine="true">//Single Line box for getting email address
</span><span style="font-family: Consolas, Monaco, 'Courier New', Courier, monospace; font-size: 12px; line-height: 18px; white-space: pre;"><EditText ... android:singleLine="false">//Multi Line box for getting email text

in case you want limit the number of lines of an EditText:

<span style="font-family: monospace; font-size: 12px; line-height: 18px; white-space: pre;"><EditText android:layout_width="fill_parent"</span>
<pre><code>            android:layout_height="wrap_content" android:gravity="center"
android:singleLine="false" android:lines="5"
android:layout_marginLeft="10dip" android:layout_marginRight="10dip"
/></code><span style="font-family: Georgia, 'Times New Roman', 'Bitstream Charter', Times, serif; font-size: 13px; line-height: 19px; white-space: normal;">

Simple Item List :
Setting up a simple Item list with an already filled Arrayadapter.

static final String[] COUNTRIES = new String[] {"Afghanistan", "Albania", "Algeria", "American Samoa", "Andorra","Angola", "..."}
<pre>setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, COUNTRIES));
getListView().setTextFilterEnabled(true);</pre>

Drop Down List :
In Android drop down list is a little bit complicated to give value to. You first need to add one Spinner to your layout and then connect it to

 String[] Countries = { "India", "France", "Japan", "China", "U.S" };

// //////////////////Countries Spinner/////////////////////////////////
SpinnerCountries = (Spinner) findViewById(R.id.Spinner01);

// //////////////////////////////////////////////////////////////
// create an arrayAdapter an assign it to the spinner
AdapterCountries = new ArrayAdapter<CharSequence>(this,
android.R.layout.simple_spinner_item);
AdapterCountries
.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
SpinnerCountries.setAdapter(AdapterCountries);

int lenCountries = Countries.length;

for (int i = 0; i < lenCountries; i++) {
// test += Areas[i] + "\n";
AdapterCountries.add(Countries[i]);
}

Disabling the Landscape Mode :
You have two ways to do this, either in the code, or in the XML layout file :

XML :

</span><span style="font-family: monospace; font-size: 12px; line-height: 18px; white-space: pre;"><activity android:name=".SomeActivity"</span>
<pre>
<pre><code>              android:label="@string/app_name"
android:screenOrientation="portrait"></code>

OR in the code :

[/java]

setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);     //  Fixed Portrait orientation[/java]

Layouts in Android :
LinearLayout :
LinearLayout aligns all children in a single direction — vertically or horizontally, depending on how you define the orientation attribute. All children are stacked one after the other, so a vertical list will only have one child per row, no matter how wide they are, and a horizontal list will only be one row high (the height of the tallest child, plus padding). A LinearLayout respects margins between children and the gravity (right, center, or left alignment) of each child.

TableLayout :
TableLayout positions its children into rows and columns. TableLayout containers do not display border lines for their rows, columns, or cells. The table will have as many columns as the row with the most cells. A table can leave cells empty, but cells cannot span columns, as they can in HTML.

RelativeLayout
RelativeLayout lets child views specify their position relative to the parent view or to each other (specified by ID). So you can align two elements by right border, or make one below another, centered in the screen, centered left, and so on. Elements are rendered in the order given, so if the first element is centered in the screen, other elements aligning themselves to that element will be aligned relative to screen center. Also, because of this ordering, if using XML to specify this layout, the element that you will reference (in order to position other view objects) must be listed in the XML file before you refer to it from the other views via its reference ID.
