ADC 11 Click

ADC 11 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.

Click Library

  • Author : Nenad Filipovic
  • Date : Feb 2021.
  • Type : SPI type

Software Support

Example Description

This library contains API for ADC 11 Click driver. The library contains drivers for measuring ADC values
and for calculation voltage.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Adc11

Example Key Functions

  • adc11_cfg_setup Config Object Initialization function.
void adc11_cfg_setup ( adc11_cfg_t *cfg );
  • adc11_init Initialization function.
err_t adc11_init ( adc11_t *ctx, adc11_cfg_t *cfg );
  • adc11_default_cfg Click Default Configuration function.
void adc11_default_cfg ( adc11_t *ctx );
  • adc11_generic_read ADC 11 data reading function.
err_t adc11_generic_read ( adc11_t *ctx, uint16_t *adc_data );
  • adc11_set_calibration ADC 11 set calibration function.
err_t adc11_set_calibration ( adc11_t *ctx, adc11_calibration_data_t *adc_val );
  • adc11_get_voltage ADC 11 get voltage function.
err_t adc11_get_voltage ( adc11_t *ctx, adc11_calibration_data_t *adc_val, float *voltage );

Application Init

Initializes SPI driver and triggers the built-in calibration.

void application_init ( void ) 
{
    log_cfg_t log_cfg;      /**< Logger config object. */
    adc11_cfg_t adc11_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 );

    // Click initialization.

    adc11_cfg_setup( &adc11_cfg );
    ADC11_MAP_MIKROBUS( adc11_cfg, MIKROBUS_1 );
    err_t init_flag  = adc11_init( &adc11, &adc11_cfg );
    if ( init_flag == SPI_MASTER_ERROR ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }
    
    log_printf( &logger, "---------------------------\r\n");
    log_printf( &logger, "        Calibration        \r\n");
    log_printf( &logger, "- - - - - - - - - - - - - -\r\n");
    log_printf( &logger, "> Turn OFF the Power unit <\r\n");
    log_printf( &logger, "- - - - - - - - - - - - - -\r\n");
    log_printf( &logger, "  In the following 5 sec.  \r\n");
    log_printf( &logger, " turn OFF the Power Supply \r\n");
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    
    log_printf( &logger, "-------------------------\r\n");
    log_printf( &logger, "    Start calibration    \r\n");
    
    if ( adc11_set_calibration( &adc11, &avg_adc_data ) == ADC11_OK ) {
        log_printf( &logger, "---------------------------\r\n");
        log_printf( &logger, "    Calibration  Done    \r\n");
        Delay_ms ( 1000 );    
    }
    
    log_printf( &logger, "---------------------------\r\n");
    log_printf( &logger, "    Start measurements :   \r\n");
    log_printf( &logger, "---------------------------\r\n");
}

Application Task

This is an example that demonstrates the use of the ADC 11 Click board. In this example, we monitor and display voltage [ V ]. Results are being sent to the Usart Terminal, where you can track their changes. All data logs write on USB UART changes every 2 sec.

void application_task ( void ) 
{
    adc11_get_voltage( &adc11, &avg_adc_data, &voltage );
    log_printf( &logger, "     Volatge : %.3f V      \r\n", voltage );
    log_printf( &logger, "---------------------------\r\n");
    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.
