DAC 24 Click

DAC 24 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

Example Description

This example demonstrates the control of DAC output voltage using the DAC 24 Click board. The application sequentially increases the DAC output voltage on all channels in equal steps.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.DAC24

Example Key Functions

• dac24_cfg_setup This function initializes Click configuration structure to initial values.

  void dac24_cfg_setup ( dac24_cfg_t *cfg );

• dac24_init This function initializes all necessary pins and peripherals used for this Click board.

  err_t dac24_init ( dac24_t *ctx, dac24_cfg_t *cfg );

• dac24_set_power_down This function sets the device in the selected power down mode.

  err_t dac24_set_power_down ( dac24_t *ctx, uint8_t pwr );

• dac24_set_dac_value This function writes the 8-bit DAC code value to one or more channels.

  err_t dac24_set_dac_value ( dac24_t *ctx, uint8_t channel, uint8_t value );

• dac24_set_dac_voltage This function sets the output voltage (in millivolts) for one or more channels.

  err_t dac24_set_dac_voltage ( dac24_t *ctx, uint8_t channel, uint16_t voltage_mv );

Application Init

Initializes the driver and logger.

void application_init ( void )
{
    log_cfg_t log_cfg;  
    dac24_cfg_t dac24_cfg;  

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    dac24_cfg_setup( &dac24_cfg );
    DAC24_MAP_MIKROBUS( dac24_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == dac24_init( &dac24, &dac24_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Gradually increases the DAC output voltage on all channels in equal steps every 2 seconds.

void application_task ( void )
{
    uint16_t step = DAC24_VCC_LEVEL / NUMBER_OF_STEPS;
    uint16_t output_voltage = step;
    for ( uint8_t cnt = 0; cnt < NUMBER_OF_STEPS; cnt++ )
    {
        if ( DAC24_OK == dac24_set_dac_voltage ( &dac24, DAC24_CHANNEL_ALL, output_voltage ) )
        {
            log_printf ( &logger, " All channels output voltage set to %u mV\r\n", output_voltage );
        }
        output_voltage += step;
        Delay_ms ( 1000 ); 
        Delay_ms ( 1000 );
    }
}

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
