ADC 13 Click

ADC 13 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 use of ADC 13 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.ADC13

Example Key Functions

• adc13_cfg_setup Config Object Initialization function.

void adc13_cfg_setup ( adc13_cfg_t *cfg );

• adc13_init Initialization function.

err_t adc13_init ( adc13_t *ctx, adc13_cfg_t *cfg );

• adc13_default_cfg Click Default Configuration function.

err_t adc13_default_cfg ( adc13_t *ctx );

• adc13_measure_voltage This function starts ADC conversation, reads RAW ADC data then calculates the voltage using the input vref for calculations.

err_t adc13_measure_voltage ( adc13_t *ctx, float vref, float *voltage );

• adc13_measure_temperature This function measures the internal temperature in Celsius.

err_t adc13_measure_temperature ( adc13_t *ctx, float *temperature );

• adc13_set_input_channel This function sets the ADC input positive and negative channels.

err_t adc13_set_input_channel ( adc13_t *ctx, uint8_t pos, uint8_t neg );

Application Init

Initializes the driver and performs the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;      /**< Logger config object. */
    adc13_cfg_t adc13_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.

    adc13_cfg_setup( &adc13_cfg );
    ADC13_MAP_MIKROBUS( adc13_cfg, MIKROBUS_1 );
    err_t init_flag  = adc13_init( &adc13, &adc13_cfg );
    if ( SPI_MASTER_ERROR == init_flag ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }
    
    adc13_default_cfg ( &adc13 );
    log_info( &logger, " Application Task " );
}

Application Task

Reads the voltage between AIN0 and AIN1 channels, and the module internal temperature as well. All values are being displayed on the USB UART where you can track their changes.

void application_task ( void )
{
    float voltage = 0;
    float temperature = 0;
    
    adc13_measure_voltage ( &adc13, ADC13_VREF_INTERNAL, &voltage );
    log_printf( &logger, " Voltage: %.3f V\r\n", voltage );
    adc13_measure_temperature ( &adc13, &temperature );
    log_printf( &logger, " Temperature: %.2f C\r\n", temperature );
    log_printf( &logger, " ---------------------------\r\n" );
    
    Delay_ms ( 500 );
}

Note

An internal 2.5V reference is set by default. If you want, you can change it using the adc13_set_voltage_reference function.

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.
