| # HAL: DAC using HAL | |
| This code example demonstrates the use of the [CTDAC HAL](https://infineon.github.io/mtb-hal-cat1/html/group__group__hal__dac.html) driver to generate a sine wave using the CTDAC component.In this example, the project uses a combination of device configurator and PDL APIs to achieve this. The voltage reference used as the reference for the CTDAC is the internal band-gap reference. The reference is buffered through internal CTBm opamps before before acting as CTDAC reference. | |

| The sine-wave output is available in pin 9[6]. | |
| ## Software setup | |
| Install a terminal emulator if you don't have one. Instructions in this document use [Tera Term](https://ttssh2.osdn.jp/index.html.en). | |
| This example requires no additional software or tools. | |
| ## Using the code example | |
| Create the project and open it using one of the following: | |
| <details><summary><b>In Eclipse IDE for ModusToolbox™ software</b></summary> | |
| 1. Click the **New Application** link in the **Quick Panel** (or, use **File** > **New** > **ModusToolbox™ Application**). This launches the [Project Creator](https://www.infineon.com/ModusToolboxProjectCreator) tool. | |
| 2. Pick a kit supported by the code example from the list shown in the **Project Creator - Choose Board Support Package (BSP)** dialog. | |
| When you select a supported kit, the example is reconfigured automatically to work with the kit. To work with a different supported kit later, use the [Library Manager](https://www.infineon.com/ModusToolboxLibraryManager) to choose the BSP for the supported kit. You can use the Library Manager to select or update the BSP and firmware libraries used in this application. To access the Library Manager, click the link from the **Quick Panel**. | |
| You can also just start the application creation process again and select a different kit. | |
| If you want to use the application for a kit not listed here, you may need to update the source files. If the kit does not have the required resources, the application may not work. | |
| 3. In the **Project Creator - Select Application** dialog, choose the example 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. | |
| For more details, see the [Eclipse IDE for ModusToolbox™ software user guide](https://www.infineon.com/MTBEclipseIDEUserGuide) (locally available at *{ModusToolbox™ software install directory}/docs_{version}/mtb_ide_user_guide.pdf*). | |
| </details> | |
| <details><summary><b>In command-line interface (CLI)</b></summary> | |
| ModusToolbox™ 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™ software install directory}/tools_{version}/project-creator/* directory. | |
| Use a CLI terminal to invoke the "project-creator-cli" tool. On Windows, use the command line "modus-shell" program provided in the ModusToolbox™ software installation instead of a standard Windows command-line application. This shell provides access to all ModusToolbox™ 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 "[mtb-example-hal-adc-basic](https://github.com/Infineon/mtb-example-hal-adc-basic)" application with the desired name "AdcBasic" configured for the *CY8CPROTO-062-4343W* BSP into the specified working directory, *C:/mtb_projects*: | |
| ``` | |
| project-creator-cli --board-id CY8CPROTO-062-4343W --app-id mtb-example-hal-adc-basic --user-app-name AdcBasic --target-dir "C:/mtb_projects" | |
| ``` | |
| **Note:** The project-creator-cli tool uses the `git clone` and `make getlibs` commands to fetch the repository and import the required libraries. For details, see the "Project creator tools" section of the [ModusToolbox™ software user guide](https://www.infineon.com/ModusToolboxUserGuide) (locally available at *{ModusToolbox™ software install directory}/docs_{version}/mtb_user_guide.pdf*). | |
| To work with a different supported kit later, use the [Library Manager](https://www.infineon.com/ModusToolboxLibraryManager) to choose the BSP for the supported kit. You can invoke the Library Manager GUI tool from the terminal using `make library-manager` command or use the Library Manager CLI tool "library-manager-cli" to change the BSP. | |
| The "library-manager-cli" tool has the following arguments: | |
| Argument | Description | Required/optional | |
| ---------|-------------|----------- | |
| `--add-bsp-name` | Name of the BSP that should be added to the application | Required | |
| `--set-active-bsp` | Name of the BSP that should be as active BSP for the application | Required | |
| `--add-bsp-version`| Specify the version of the BSP that should be added to the application if you do not wish to use the latest from manifest | Optional | |
| `--add-bsp-location`| Specify the location of the BSP (local/shared) if you prefer to add the BSP in a shared path | Optional | |
| <br /> | |
| Following example adds the CY8CPROTO-062-4343W BSP to the already created application and makes it the active BSP for the app: | |
| ``` | |
| library-manager-cli --project "C:/mtb_projects/AdcBasic" --add-bsp-name CY8CPROTO-062-4343W --add-bsp-version "latest-v4.X" --add-bsp-location "local" | |
| library-manager-cli --project "C:/mtb_projects/AdcBasic" --set-active-bsp APP_CY8CPROTO-062-4343W | |
| ``` | |
| </details> | |
| <details><summary><b>In third-party IDEs</b></summary> | |
| Use one of the following options: | |
| - **Use the standalone [Project Creator](https://www.infineon.com/ModusToolboxProjectCreator) tool:** | |
| 1. Launch Project Creator from the Windows Start menu or from *{ModusToolbox™ software install directory}/tools_{version}/project-creator/project-creator.exe*. | |

| 2. In the **Quick Panel**, scroll down, and click **\<Application Name> Program (KitProg3_MiniProg4)**. | |
| </details> | |
| <details><summary><b>Using CLI</b></summary> | |
| From the terminal, execute the `make program` command to build and program the application using the default toolchain to the default target. The default toolchain is specified in the application's Makefile but you can override this value manually: | |
| ``` | |
| make program TOOLCHAIN=<toolchain> | |
| ``` | |
| Example: | |
| ``` | |
| make program TOOLCHAIN=GCC_ARM | |
| ``` | |
| </details> | |
| 3. After programming, the application starts automatically. Ensure that output pin 9[6] is connected to oscilloscope. | |
| 4. You can observe the generated sine wave | |
| **Figure 1. Oscilloscope image** | |
|  | |
| ## Debugging | |
| You can debug the example to step through the code. In the IDE, use the **\<Application Name> Debug (KitProg3_MiniProg4)** configuration in the **Quick Panel**. For details, see the "Program and debug" section in the [Eclipse IDE for ModusToolbox™ software user guide](https://www.infineon.com/MTBEclipseIDEUserGuide). | |
| ## Design and implementation | |
| In this example, | |
| All the components are configured in design.modus | |
| CTDAC is reference is set as internal Vref buffered through internal opamp. | |
| CTBm block opamp is set as to act as buffer for internal reference to be connected to CTDAC as source. | |
| DMA is configured to transfer 100 elements in the form of a descriptor, which transfers one element on each trigger. | |
| The lookup table for sine wave is stored in 12 bit unsigned mode. | |
| The components are initialized and enabled. | |
| The DMA source and destination address are set as Lookup table address and CTDAC buffer address respectively. | |
| The descriptor is looped back to itself for continuous wave generation | |
| The maximum amplitude of the waveform will be dependent on the reference provided. Higher amplitude references can be provided (VDDA/External), keeping in mind that it is within maximum specifications | |
