            Choose which DAC channels will be used:
            - CH0: GPIO25 (ESP32) / GPIO17 (ESP32-S2)
            - CH1: GPIO26 (ESP32) / GPIO18 (ESP32-S2)
            - Both CH0 and CH1: Both channels active simultaneously.

        config WAVEU_DAC_CHANNEL_CH0
            bool "CH0 only"

                Enable only DAC Channel 0 for output (GPIO25 on ESP32, GPIO17 on ESP32-S2).

                Enable only DAC Channel 1 for output (GPIO26 on ESP32, GPIO18 on ESP32-S2).

        bool "Enable digital signal 1 for waveform data generation on GPIO"
        default n
        help
            Enable this option to output a digital signal reflecting waveform data generation
            to a GPIO pin. Useful for debugging and performance analysis.

    if WAVEU_DEBUG_PRODUCER_GPIO

                Specify the GPIO pin number to use for debugging.
                Ensure the specified GPIO pin is valid for your board.

    config WAVEU_DEBUG_CONSUMER_GPIO
        bool "Enable digital signal 2 for DAC transfer on GPIO"
        default n
        help
            Enable this option to output a digital signal reflecting DAC data transfer to a GPIO pin.
            Useful for debugging and ensuring real-time transfer correctness.

        help
            Specify how the DAC channels should interpret the data in the buffer:
            - Simultaneous mode: Both channels output identical data.
            - Alternate mode: Channels alternate data values in the buffer, e.g.,
            Channel 0: A, C, E; Channel 1: B, D, F.

            The DAC outputs data continuously using DMA or timer-driven transfer.

        range 1 20

        help
            Specify the priority of the waveform generation task. Higher values
            indicate higher priority. Valid range: 1 (lowest) to 20 (highest).

        bool "Run DAC transfer task on Core 0"
        default y
        help
            Select this option to pin the DAC transfer task to Core 0.
            If disabled, the task will run on Core 1.

        range 1 20
        default 10
        help
            Specify the priority of the DAC transfer task. Higher values indicate
            higher priority. Valid range: 1 (lowest) to 20 (highest).

    choice WAVEU_LUT_TYPE
        prompt "Select Lookup Table (LUT) data type"
        help
            Specify the data type used for the waveform LUT:
            - int16_t: 16-bit signed integer.
            - uint16_t: 16-bit unsigned integer.
            - uint8_t: 8-bit unsigned integer (uses less memory, but lower resolution).
