# PSoC™ 6 MCU: CSD current output digital-to-analog converter (IDAC)
This code example demonstrates using the CSD hardware-block-based current digital-to-analog converter (CSDIDAC) as a current source and a current sink. CSDIDAC supports two channels - A and B. Channel A is configured as a current source. The current increases when a switch is pressed. Once the output reaches its maximum value, it resets to zero and starts to increase the value again. The last current output value is maintained when the switch is not pressed. UART displays the current value for which the CSDIDAC is configured. Channel B is configured for sinking current and used for driving an LED. The firmware enables or disables the IDAC channel to toggle the LED every second. This project uses [CSDIDAC middleware library](https://github.com/Infineon/csdidac).

## Operation
1. Connect the board to your PC using the provided USB cable through the KitProg3 USB connector.
2. Open a terminal program and select the KitProg3 COM port. Set the serial port parameters to 8N1 and 115200 baud.
3. Program the board using one of the following:
<details><summary><b>Using Eclipse IDE for ModusToolbox&trade;</b></summary>
1. Select the application project in the Project Explorer.
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>
4. After programming, the application starts automatically. Confirm that the UART terminal displays the following.
**Figure 1. Terminal output**
![](images/terminaloutput_1.png)
5. Press the user button. The terminal should show the new current value for which the IDAC current source is configured, as shown in **Figure 2**. Calculate the current by measuring the voltage across the resistor connected between P10[0] and the ground (GND). The current value should match the value shown on the terminal.
**Figure 2. Terminal output when button pressed**
![](images/terminaloutput_2.png)
## 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&trade; user guide](https://www.infineon.com/MTBEclipseIDEUserGuide).
**Note:** **(Only while debugging)** On the CM4 CPU, some code in `main()` may execute before the debugger halts at the beginning of `main()`. This means that some code executes twice – once before the debugger stops execution, and again after the debugger resets the program counter to the beginning of `main()`. See [KBA231071](https://community.infineon.com/docs/DOC-21143) to learn about this and for the workaround.
## Design and implementation
CSDIDAC supports two channels (A and B) IDAC with 7-bit resolution. Configure both channels independently for sourcing or sinking current. See [CSDIDAC middleware library](https://github.com/Infineon/csdidac) for more details. In this code example, channel A is configured for sourcing current; firmware controls the current value. Channel B is configured for sinking current and used for driving the LED. The CSDIDAC could be configured by the ModusToolbox&trade; CSD personality. See the [Configuration considerations section](https://infineon.github.io/csdidac/csdidac_api_reference_manual/html/index.html#group_csdidac_configuration) in the API reference guide for configuring the CSDIDAC.
The CSDIDAC is not enabled in the default board configuration provided by the BSP. This example overrides the `BSP_DESIGN_MODUS` component provided with the BSP to enable and configure the CSDIDAC. See the "Overriding the BSP Configuration files" section of the [ModusToolbox™ user guide](https://www.infineon.com/ModusToolboxUserGuide): *{ModusToolbox&trade; install directory}/ide_{version}/docs/mtb_user_guide.pdf*
The *design.modus* file containing the custom device configuration used in this application is present under the respective kit's folder: *\<application_folder>/templates/TARGET_\<BSP-NAME>/config/design.modus*.
## Enabling the CSDIDAC functionality
This section guides how to set up the CSDIDAC middleware for the CSDIDAC operation using ModusToolbox&trade;.
1. Launch the **Device configurator** tool from the Quick Panel of the IDE. This opens the design.modus file located in *\<application_folder>/templates/TARGET_\<BSP-NAME>/config/design.modus*.
2. On the **System** tab, configure the **CLK_PERI** frequency to achieve the desired frequency. This is the clock input to the CSDIDAC.
3. On the **Peripherals** tab (#1 in **Figure 2**), enable the **CSD** personality under **System** (#2 in **Figure 3**) and enter the **Alias** (#3 in **Figure 3**).
4. Go to the **Parameters** pane and configure the CSD personality:
1. Assign the peripheral clock divider by using the **Clock** combo box (#4 in **Figure 3**). Any free divider can be used.
2. Set the **Enable CSDIDAC** check box (#5 in **Figure 3**).
3. Configure the CSDIDAC parameters (#5 in **Figure 3**).
4. Assign the CSDIDAC channels to pins (#6 in **Figure 3**).
5. Select **File** > **Save** to generate the initialization code. This is executed as part of the `init_cycfg_all()` function, which is called by `cybsp_init()`.
