Step Up 2 Click

Step Up 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.

Example Description

This example demonstrates the use of the Step Up 2 Click board by changing the output voltage.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.StepUp2

Example Key Functions

• stepup2_cfg_setup Config Object Initialization function.

void stepup2_cfg_setup ( stepup2_cfg_t *cfg );

• stepup2_init Initialization function.

err_t stepup2_init ( stepup2_t *ctx, stepup2_cfg_t *cfg );

• stepup2_default_cfg Click Default Configuration function.

err_t stepup2_default_cfg ( stepup2_t *ctx );

• stepup2_set_vout This function sets the voltage output level.

err_t stepup2_set_vout ( stepup2_t *ctx, stepup2_vout_t vout );

• stepup2_set_resistance This function sets a desired resistance by writing to the volatile memory register and the wiper position.

err_t stepup2_set_resistance ( stepup2_t *ctx, float res_kohm );

• stepup2_enable This function turns on the power switch and enables the boost mode.

void stepup2_enable ( stepup2_t *ctx );

Application Init

Initialization of I2C module and log UART. After driver initialization, the app executes a default configuration.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    stepup2_cfg_t stepup2_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.
    stepup2_cfg_setup( &stepup2_cfg );
    STEPUP2_MAP_MIKROBUS( stepup2_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == stepup2_init( &stepup2, &stepup2_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( STEPUP2_ERROR == stepup2_default_cfg ( &stepup2 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

The demo application changes the output voltage and displays the current voltage output value. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void ) 
{
    float vout_table[ 15 ] = { STEPUP2_VOUT_LIST };
    for ( stepup2_vout_t vout = STEPUP2_VOUT_5V5; vout <= STEPUP2_VOUT_3V3; vout++ )
    {
        if ( STEPUP2_OK == stepup2_set_vout( &stepup2, vout ) )
        {
            log_printf( &logger, " Voltage: %.2f[V]\r\n\n", vout_table[ vout ] );
            Delay_ms ( 1000 );
            Delay_ms ( 1000 );
            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.
