Qt Creator is a cross-platform Open Source Integrated Development Environment (IDE) that can be used to develop software for many different languages. It includes a visual debugger and an integrated GUI layout and forms designer. See the Qt Project site for more information http://qt-project.org/wiki/Category:Tools::QtCreator.

After installing EMAC SDK, launch the EMAC Qt Creator desktop icon.

1. Press the Windows key and search for '''Qt Creator EMAC'''

2. Put the Qt Creator EMAC icon on the Launcher for easy access.

<br clear=all>

3. To generate a new project from Qt Creator, select '''New Project''' on the opening splash window. The examples being used are all written in <code> C programming </code> language.

[[File:Qtcreator_gui.png|600px|left|thumb|Figure 2: Qt Creator GUI]]
<br clear=all>

4. After selecting '''New Project''' a new window will pop up. To run a <code> C programming </code> example using EMAC hardware, select '''EMAC Project''' under the Projects tab. Then select '''EMAC C Project (CMake Build)'''. Click the '''Choose''' button on the bottom right of window to continue to the next page as shown in Figure 3.

[[File:EMAC_C_Project.png|600px|left|thumb|Figure 3: Qt Creator EMAC Project]]
<br clear=all>

5. The next page will be '''Introduction and Project Location'''. Select a name for the <code> C </code> project. Once the project name is given, choose a a directory to store the project. Note: It is highly recommended to store your project other than the default location. For this example, we used ''/home/developer/Projects''.

[[File:Project_location1.png|600px|left|thumb|Figure 4: Qt Creator Project Location]]
<br clear=all>

6. The next page summarizes the '''EMAC C Project'''. Click '''Finish''' to continue.

[[File:Project_summary1.png|600px|left|thumb|Figure 5: Qt Creator Project Summary]]
<br clear=all>

7. Next, it will prompt you to the '''CMake Wizard Build Location'''. Click '''Next''' to continue. Note: It is highly recommended to use the default build directory as stated below in Figure 6. 

[[File:Build_location.png|600px|left|thumb|Figure 6: Qt Creator Build Location]] 
<br clear=all>

8. '''CMake Wizard''' will then prompt you to '''Run CMake'''. For setting up the Desktop Kit, click '''Run CMake''' and the output should be similar to Figure 7 below. Click '''Finish''' to start new project.

[[File:Run_cmake1.png|600px|left|thumb|Figure 7: Qt Creator Run CMake]]
<br clear=all>

9. The next step is to setup your device which you'll be using for the Qt Creator examples. Click Tools -> Options
{{note|The board being used will be the iPac-9x25. The iPac-9x25 is a 32-bit ARM architecture.}}

10. Select '''Devices''' from the left pane.

[[File:Options_devices.png|600px|left|thumb|Figure 8: Qt Creator Device Option]]
<br clear=all>

11. Press the '''Add''' button

12. Select Generic Linux Device, then press '''Start Wizard'''.

14. Click '''Next'''.

15. Click '''Finish'''.

16. A connection will be established with the target device.

[[File:Device_test.png|600px|left|thumb|Figure 11: Qt Creator Device Test]]
<br clear=all>

17. Click '''Close'''.

18. Click '''Apply'''.

19. Once the Desktop Kit is configured, and the device is setup the hardware architecture kit needs to be installed. Navigate to '''Add Kit''' in the '''Projects''' tab. Under '''Add Kit''' select the architecture for the board being used. Click '''EMAC OE 5.0 arm'''.  


[[File:Add_kit_arm.jpg|600px|left|thumb|Figure 12: Qt Creator Add Kit]]
<br clear=all>

20. As previously stated in step 7 it will prompt you to the '''CMake Wizard Build Location'''. Click '''Next''' to continue. Note: It is highly recommended to use the default build directory as stated below in Figure 13.

[[File:Add_arm.png|600px|left|thumb|Figure 13: Qt Creator Add Kit Build Location]]
<br clear=all>

21. '''CMake Wizard''' will then prompt you to '''Run CMake'''. For setting up the iPac-9x25 arm kit, click the box next to '''Arguments'''. Copy and paste the string below:   
 ''-DARCH:STRING=arm''

[[File:Arm_argument_string.png|600px|left|thumb|Figure 14: Qt Creator Argument String]]
<br clear=all>

EMAC SDK provides another architectural kit for x86 hardware. If using an x86 architecture, copy and paste the argument string below in the '''Arguments''' box.  
 ''-DARCH:STRING=x86''  

22. Once the arguments string is pasted in the box, click '''Run CMake''' and the output should be similar to Figure 15 below. Click '''Finish''' to add the arm kit to the current project.

[[File:Run_arm_cmake.png|600px|left|thumb|Figure 15: Qt Creator Run CMake]]
<br clear=all>

23. To confirm if the kits installed correctly, click on the '''Kit Selector''' tab (Monitor symbol) on the left hand side of the Qt Creator window as shown in Figure 16. Both '''Desktop''' and '''OE 5.0 arm''' kit will be present.

[[File:Arm_kit.jpg|600px|left|thumb|Figure 16: Qt Creator Kits Installed]]
<br clear=all>

24. To run the example projects on the target board remotely, you'll need to add it to the '''Run Configuration'''. Click on '''Projects'''.

25. Select '''Run''' under the '''OE 5.0 arm''' tab.

26. Next to '''Run Configuration''', click on '''Add''' and select your project name (on Remote Generic Linux Host). In this case, our project name is Prime_Numbers (on Remote Generic Linux Host).

You are now all set up to run the examples below on Qt Creator.

{{:Templateimpl:examples | initials=BS | title=Getting Started with Qt Creator | desc=The following page can be used to get familiarized with EMAC Qt Creator. | project=OE 5.0 }}
This section will show how to run <code> C programming </code> examples through the Qt Creator IDE.  The example board will be the iPac-9x25. 

The first example is a basic <code> hello c </code> example project. 

1. After creating a new project and installing the necessary kits for the target board, navigate to the '''Edit''' tab on Qt Creator. Qt Creator will automatically have the <code> hello c </code> example uploaded as shown in Figure 18.

<syntaxhighlight lang="c">
#include <stdio.h>
#include <stdlib.h>

int main(int argc, char * argv[])
{
    printf("Hello EMAC OE!\n");
   
    exit(EXIT_SUCCESS);
}
</syntaxhighlight>

[[File:Edit_window.png|600px|left|thumb|Figure 18: Qt Creator Edit Window]] 
<br clear=all>

2. Before executing the example, you must build the program first. Click on the build icon (hammer symbol) on the bottom left of Qt Creator. If the build was successful, a green bar will fill on the bottom right of the window.

3. Once the program successfully builds, you can now run the program. Click on the run icon (green arrow symbol) on the left hand side of Qt Creator. The program prints <code> Hello EMAC OE! </code> in the '''Application Output''' terminal. 

[[File:Final_output.png|600px|left|thumb|Figure 19: Qt Creator Edit Window]]
<br clear=all>

The second example will show how to run a <code> c programming </code> project on a target board. This example will show all prime numbers from 1 - 100 and output it on Qt Creator remote terminal.

1. Create a new project and install the necessary kits for the target board just as shown before. Call this project <code> Prime_Numbers </code>. Then Navigate to the '''Edit''' tab on Qt Creator. Copy and paste the following code below to the Qt Creator terminal. 

<syntaxhighlight lang="c">
#include <stdio.h>
#include <stdlib.h>

int main(int argc, char * argv[])
{ 
  int i;
  int j;

  for (i = 2; i <= 100; i++)
  {
    for (j = 2; j <= i; j++)
    {
      if (i%j==0)
      {
        break;
      }
    }
    if (i == j)
    {
      printf ("%d is a prime number. \n", i);
    }
  }
  return 0;
}
</syntaxhighlight>

2. Click on the build icon (hammer symbol) on the bottom left of the Qt Creator. If the build was successful, a green bar will fill on the bottom right of Qt Creator.

3. Click on the run icon (green arrow symbol) on the left hand side of Qt Creator. The program prints all prime numbers from 1 - 100 in the '''Application Output''' terminal.
