Step Down 2 Click

Step Down 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 showcases how to initialize and use the Step Down 2 Click. The Click is a step-down monolithic switching regulator able to deliver up to 2 A (DC).

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.StepDown2

Example Key Functions

• stepdown2_cfg_setup Config Object Initialization function.

void stepdown2_cfg_setup ( stepdown2_cfg_t *cfg );

• stepdown2_init Initialization function.

err_t stepdown2_init ( stepdown2_t *ctx, stepdown2_cfg_t *cfg );

• stepdown2_default_cfg Click Default Configuration function.

void stepdown2_default_cfg ( stepdown2_t *ctx );

• stepdown2_digital_read_rst This function reads the digital signal from the RST pin.

uint8_t stepdown2_digital_read_rst ( stepdown2_t *ctx );

• stepdown2_digital_write_cs This function writes the specified digital signal to the CS pin.

void stepdown2_digital_write_cs ( stepdown2_t *ctx, uint8_t signal );

Application Init

This function initializes and configures the logger and Click modules.

void application_init ( )
{
    log_cfg_t log_cfg;
    stepdown2_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.

    stepdown2_cfg_setup( &cfg );
    STEPDOWN2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    stepdown2_init( &stepdown2, &cfg );

    stepdown2_digital_write_cs( &stepdown2, 1 );
    Delay_100ms( );
}

Application Task

This function checks error input on the RST pin and reports if the device is working properly or not. It does so every second.

void application_task ( )
{
    if ( stepdown2_digital_read_rst( &stepdown2 ) )
    {
        log_printf( &logger, " * The device works as it should. *\r\n" );
    }
    else 
    {
        log_printf( &logger, " * The device does not work as it should. *\r\n" );
    }

    Delay_1sec( );
} 

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.
