After installing the EMAC SDK, launch Qt Creator using the EMAC Qt Creator desktop icon.
+
1. Launch Qt Creator using one of the following methods:
 +
* Click the Qt Creator icon on the the desktop
 +
* In the terminal, execute the following commands:
 +
{{cli | username=developer | hostname=ldc | cd ~/EMAC-SDK/emac-QtCreator/bin }}
 +
{{cli | username=developer | hostname=ldc | pwd=~/EMAC-SDK/emac-QtCreator/bin | ./qtcreator.sh }}
  
−

−
2. Put the Qt Creator EMAC icon on the Launcher for easy access.
+
2. To generate a new project from Qt Creator, select '''New Project''' on the opening splash window. The examples being used are all written in the <code>C programming</code> language.

The following page demonstrates the process of getting familiar with EMAC Qt Creator and running it on the target machine.

Background

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.

For more information visit the Qt Project site http://qt-project.org/wiki/Category:Tools::QtCreator.

General Information

Tools Required

These tools should already be installed if you installed the EMAC SDK using the automatic installer.

Setup

  1. Make sure the system has the EMAC OE 5.X SDK and tools installed.
  2. Launch EMAC Qt Creator.

Getting Started with Qt Creator

1. Launch Qt Creator using one of the following methods:

  • Click the Qt Creator icon on the the desktop
  • In the terminal, execute the following commands:
developer@ldc:~# cd ~/EMAC-SDK/emac-QtCreator/bin
developer@ldc:~/EMAC-SDK/emac-QtCreator/bin# ./qtcreator.sh


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

File:QtCreatorGUInew.png
Figure 1: Qt Creator GUI


3. After selecting New Project a new window will pop up. To run a C programming 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 the window to continue to the next page as shown in Figure 3.

Figure 2: Qt Creator EMAC Project


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

Figure 3: Qt Creator Project Location


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

Figure 4: Qt Creator Project Summary


6. The next step is to set up the device you will be using for the Qt Creator examples. Click Tools -> Options



NOTE
The board used for this example is the iPac-9x25. The iPac-9x25 is a 32-bit ARM architecture. Make sure to connect power, Ethernet, and serial to the board.


7. Select Devices from the left pane.

Figure 5: Qt Creator Device Option


8. Click the Add button

9. Select Generic Linux Device, then click Start Wizard.

Figure 6: Qt Creator Wizard Selection


10. Type in a name, the IP address, the user name, and the password for the device. Use the credentials below to sign in.

Username Password
root emac_inc
Figure 7: Qt Creator Configuration Setup


11. Click Next.

12. Click Finish.

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

Figure 8: Qt Creator Device Test


14. Click Close.

15. Click Apply.

16. Navigate to the Projects tab. Here, Qt Creator will ask you to select which kits you will be using with the project. For this example, we made sure the arm kit was selected. Then click Configure Project.

Figure 9: Configureing Qt Project


17. Now, on the left side of Qt Creator, you will see the project icon, which looks like a monitor. Click this and make sure Arm is selected under Kit, Default is selected under Build, and the project is set to be run on the remote device under Run.

Figure 10: Selecting Qt Kit


18. Now, simply press the green play button. The program should run on the target device and yield an output.

Conclusion

This page is a quick getting started tutorial on how to use EMAC Qt Creator for the first time. It shows you how to create an EMAC C Project, how to set up the necessary kits for your target board, how to set up your target board, and how to build and run example projects.
