ADC 2 Click

ADC 2 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 : MikroE Team
  • Date : Jan 2020.
  • Type : SPI type

Software Support

Example Description

This application enables usage of the 22bit ADC.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.Adc2

Example Key Functions

  • adc2_cfg_setup Config Object Initialization function.
void adc2_cfg_setup ( adc2_cfg_t *cfg );
  • adc2_init Initialization function.
err_t adc2_init ( adc2_t *ctx, adc2_cfg_t *cfg );
  • adc2_default_cfg Click Default Configuration function.
void adc2_default_cfg ( adc2_t *ctx );
  • adc2_check_over_high Function is used to check overflow high state.
uint8_t adc2_check_over_high ( adc2_t *ctx );
  • adc2_check_over_low Function is used to check overflow low state.
uint8_t adc2_check_over_low ( adc2_t *ctx );
  • adc2_adc_value_read Function is used to read specific data from ADC convertor.
uint32_t adc2_adc_value_read ( adc2_t *ctx );

Application Init

Initalizes SPI driver and makes an initial log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    adc2_cfg_t cfg;

    /** 
     * 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.

    adc2_cfg_setup( &cfg );
    ADC2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    adc2_init( &adc2, &cfg );

    Delay_ms ( 100 );

    log_printf( &logger, "------------------\r\n" );
    log_printf( &logger, "    ADC 2 Click   \r\n" );
    log_printf( &logger, "------------------\r\n" );
}

Application Task

This is an example that shows the capabilities of the ADC 2 Click

void application_task ( void )
{
    uint32_t adc_val;

    //  Task implementation.

    adc_val = adc2_adc_value_read( &adc2 );

    log_printf( &logger, "Value : %d", adc_val );
    log_printf( &logger, "------------------\r\n" );
    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.
