DigiVref Click

DigiVref 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.

Software Support

Example Description

This app changes the reference output voltage.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.DigiVref

Example Key Functions

• digivref_cfg_setup Config Object Initialization function.

void digivref_cfg_setup ( digivref_cfg_t *cfg );

• digivref_init Initialization function.

err_t digivref_init ( digivref_t *ctx, digivref_cfg_t *cfg );

• digivref_default_cfg Click Default Configuration function.

void digivref_default_cfg ( digivref_t *ctx );

• digivref_set_output_voltage This function sets reference output voltage.

void digivref_set_output_voltage ( digivref_t *ctx, uint8_t v_ref );

Application Init

Initialization device.

void application_init ( void )
{
    log_cfg_t log_cfg;
    digivref_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.

    digivref_cfg_setup( &cfg );
    DIGIVREF_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    digivref_init( &digivref, &cfg );
}

Application Task

Changes the reference output voltage every 3 seconds.

void application_task ( void )
{
    digivref_set_output_voltage( &digivref, DIGIVREF_REF_VOLTAGE_4096mV );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    digivref_set_output_voltage(  &digivref, DIGIVREF_REF_VOLTAGE_3072mV );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    digivref_set_output_voltage( &digivref, DIGIVREF_REF_VOLTAGE_2048mV );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    digivref_set_output_voltage( &digivref, DIGIVREF_REF_VOLTAGE_1024mV );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    digivref_set_output_voltage( &digivref, DIGIVREF_REF_VOLTAGE_2048mV );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    digivref_set_output_voltage( &digivref, DIGIVREF_REF_VOLTAGE_3072mV );
    Delay_ms ( 1000 );
    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.
