## Using the code example

Create the project and open it using one of the following:

<details open><summary><b>In Eclipse IDE for ModusToolbox&trade; software (recommended)</b></summary>

1. Click the **New Application** link in the **Quick Panel** (or, use **File** > **New** > **ModusToolbox&trade; Application**). This launches the [Project Creator](https://www.infineon.com/ModusToolboxProjectCreator) tool.

2. Select the kit `KIT_XMC13_BOOT_001` from the **XMC&trade; BSPs** list shown in the **Project Creator - Choose Board Support Package (BSP)** dialog.

3. In the **Project Creator - Select Application** dialog, choose the example from the list **Community Code Examples** by enabling the checkbox.

4. (Optional) Change the suggested **New Application Name**.

5. The **Application(s) Root Path** defaults to the Eclipse workspace which is usually the desired location for the application. If you want to store the application in a different location, you can change the *Application(s) Root Path* value. Applications that share libraries should be in the same root path.

6. Click **Create** to complete the application creation process.

7. To build the project, click **Build Application** from the Quick Panel.

8. To start the debugging session to run the motor, click **Generate Launches for "YourApplicationName"** in Quick Panel. Then click to **YourApplicationName Debug (Jlink)**. A debugging window will appear and the session will automatically pause in a breakpoint. Click **Resume** button from the above toolbar to continue the session.

9. While the debugging session is running, open the Micro Inspector Pro application. Click **Open Workspace** button from the upper left corner.

**Note:** This code does not use the Device Configurator in ModusToolbox. All peripheral definitions and initializations are directly integrated within the software using low level drivers by calling the necessary libraries. When the user wants to change a configuration variable or parameter, it should be done within the code in the user config header files rather than in the Device Configurator.

<details open><summary><b>In command-line interface (CLI)</b></summary>


ModusToolbox&trade; software provides the Project Creator as both a GUI tool and the command line tool, "project-creator-cli". The CLI tool can be used to create applications from a CLI terminal or from within batch files or shell scripts. This tool is available in the *{ModusToolbox&trade; software install directory}/tools_{version}/project-creator/* directory.

Alternatively, you can manually create the application using the following steps:

1. Download and unzip this repository onto your local machine, or clone the repository.

2. Use a CLI terminal to invoke the "project-creator-cli" tool. On Windows, use the command line "modus-shell" program provided in the ModusToolbox&trade; software installation instead of a standard Windows command-line application. This shell provides access to all ModusToolbox&trade; software tools. You can access it by typing `modus-shell` in the search box in the Windows menu. In Linux and macOS, you can use any terminal application.

The "project-creator-cli" tool has the following arguments:

Argument | Description | Required/optional
---------|-------------|-----------
`--board-id` | Defined in the `<id>` field of the [BSP](https://github.com/Infineon?q=bsp-manifest&type=&language=&sort=) manifest | Required
`--app-id`   | Defined in the `<id>` field of the [CE](https://github.com/Infineon?q=ce-manifest&type=&language=&sort=) manifest | Required
`--target-dir`| Specify the directory in which the application is to be created if you prefer not to use the default current working directory | Optional
`--user-app-name`| Specify the name of the application if you prefer to have a name other than the example's default name | Optional

<br />

The following example clones the "[BLDC Scalar SL XMC13](https://github.com/Infineon/cce-mtb-xmc-bldc-scalar-sl)" application with the desired name "cce-mtb-xmc-bldc-scalar-sl" configured for the *KIT_XMC13_BOOT_001* BSP into the specified working directory, *C:/mtb_projects*:

   ```
   project-creator-cli --board-id KIT_XMC13_BOOT_001 --app-id cce-mtb-xmc-bldc-scalar-sl --user-app-name cce-mtb-xmc-bldc-scalar-sl --target-dir "C:/mtb_projects"
   ```
   
   **Note:** The cloned application contains a default BSP file (*TARGET_xxx.mtb*) in the *bsps* folder. Use the [Library Manager](https://www.infineon.com/ModusToolboxLibraryManager) (`make modlibs` command) to select or add a different BSP file, if required. If the selected kit does not have the required resources or is not supported, the application may not work.

3. Import the required libraries by executing the `make getlibs` command.

Various CLI tools include a `-h` option that prints help information to the terminal screen about that tool. For more details, see the [ModusToolbox&trade; software user guide](https://www.infineon.com/ModusToolboxUserGuide) (locally available at *{ModusToolbox&trade; software install directory}/docs_{version}/mtb_user_guide.pdf*).

</details>

<details open><summary><b>In third-party IDEs</b></summary>

**Note:** Only VS Code is supported.

1. Follow the instructions from the **In command-line interface (CLI)** section to create the application, and import the libraries using the `make getlibs` command.

2. Export the application to a supported IDE using the `make <ide>` command.

   For a list of supported IDEs and more details, see the "Exporting to IDEs" section of the [ModusToolbox&trade; software user guide](https://www.infineon.com/ModusToolboxUserGuide) (locally available at *{ModusToolbox&trade; software install directory}/docs_{version}/mtb_user_guide.pdf*).

3. Follow the instructions displayed in the terminal to create or import the application as an IDE project.
