ADC 10 Click

ADC 10 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 is an example that demonstrates the use of the ADC 10 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Adc10

Example Key Functions

• adc10_cfg_setup Config Object Initialization function.

  void adc10_cfg_setup ( adc10_cfg_t *cfg );

• adc10_init Initialization function.

  err_t adc10_init ( adc10_t *ctx, adc10_cfg_t *cfg );

• adc10_default_cfg Click Default Configuration function.

  void adc10_default_cfg ( adc10_t *ctx );

• adc10_start_sync ADC 10 Start the synchronization function.

  void adc10_start_sync ( adc10_t *ctx );

• adc10_get_ch_output ADC 10 Get the channel output function.

  int32_t adc10_get_ch_output ( adc10_t *ctx, uint8_t sel_ch );

• adc10_calc_voltage ADC 10 Calculate the voltage function.

  float adc10_calc_voltage ( adc10_t *ctx, int32_t adc_data, float vref, uint8_t gain );

Application Init

Initialization driver enables - UART, select analog input channel 0, perform a hardware and software reset and set the default device configuration, also, write a log.

void application_init ( void ) 
{
    log_cfg_t log_cfg;      
    adc10_cfg_t adc10_cfg;  

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_printf( &logger, "\r\n-------------------------\r\n" );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
 
    adc10_cfg_setup( &adc10_cfg );
    ADC10_MAP_MIKROBUS( adc10_cfg, MIKROBUS_1 );
    err_t init_flag  = adc10_init( &adc10, &adc10_cfg );
    if ( init_flag == UART_ERROR ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );
 
        for ( ; ; );
    }
    
    select_ch = ADC10_ANALOG_INPUT_CH_3;
    
    // Hardware reset.
    
    adc10_hw_reset( &adc10 );
    Delay_ms ( 100 );
    
    // Software reset.
    
    adc10_reset( &adc10 );
    Delay_ms ( 1000 );
 
    // Click default configuration.
    
    adc10_default_cfg ( &adc10 );
    log_info( &logger, " Application Task " );
    Delay_ms ( 100 );
}

Application Task

In this example, we monitor and display 24-bits of data ( from 0 to 8388607 ) of ADC and voltage ( from 0 mV to 2048 mV ) on the selected channel ( CH-0, CH-1, CH-2 or CH-3 ). Results are being sent to the Usart Terminal where you can track their changes. All data logs write on USB uart changes approximately for every 1 sec.

void application_task ( void ) 
{   
    adc10_start_sync( &adc10 );
    Delay_ms ( 1 );
 
    while ( adc10_check_drdy( &adc10 ) == ADC10_NEW_DATA_NOT_READY );
 
    out_data = adc10_get_ch_output( &adc10, select_ch );
    log_printf( &logger, "-------------------------\r\n" );
    log_printf( &logger, "  ADC CH-%u : %.0f\r\n", ( uint16_t ) select_ch, ( float ) out_data );
 
    voltage = adc10_calc_voltage( &adc10, out_data, ADC10_VREF_INTERNAL, ADC10_GAIN_1 );
    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.
