ADC 14 Click

ADC 14 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.

• Date : Aug 2023.
• Type : SPI type

Software Support

Example Description

This example demonstrates the use of the ADC 14 Click board™ by reading results of AD conversion by using SPI serial interface.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.ADC14

Example Key Functions

• adc14_cfg_setup Config Object Initialization function.

void adc14_cfg_setup ( adc14_cfg_t *cfg );

• adc14_init Initialization function.

err_t adc14_init ( adc14_t *ctx, adc14_cfg_t *cfg );

• adc14_get_voltage ADC 14 get voltage function.

err_t adc14_get_voltage ( adc14_t *ctx, float *voltage );

• adc14_read_conversion_data ADC 14 read conversion data function.

err_t adc14_read_conversion_data ( adc14_t *ctx, uint16_t *adc_data );

• adc14_set_vref ADC 14 set voltage reference function.

err_t adc14_set_vref ( adc14_t *ctx, float vref );

Application Init

Initialization of SPI module and log UART and enabled internal voltage reference.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    adc14_cfg_t adc14_cfg;  /**< Click config object. */

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @note If USB_UART_RX and USB_UART_TX 
     * are defined as HAL_PIN_NC, you will 
     * need to define them manually for log to work. 
     * See @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );

    // Click initialization.
    adc14_cfg_setup( &adc14_cfg );
    ADC14_MAP_MIKROBUS( adc14_cfg, MIKROBUS_POSITION_ADC14 );
    if ( SPI_MASTER_ERROR == adc14_init( &adc14, &adc14_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
    Delay_ms ( 100 );
}

Application Task

The demo application gets the voltage levels from analog input and displays the results. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void )
{
    float voltage = 0.0;
    if ( ADC14_OK == adc14_get_voltage( &adc14, &voltage ) )
    {
        log_printf( &logger, " Voltage : %.2f [mV]\r\n", voltage );
        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.
