Buck-Boost Click

Buck-Boost 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

The demo application change output voltage from 2500 mV to 15000 mV every 5 seconds.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.BuckBoost

Example Key Functions

• buckboost_cfg_setup Config Object Initialization function.

void buckboost_cfg_setup ( buckboost_cfg_t *cfg );

• buckboost_init Initialization function.

err_t buckboost_init ( buckboost_t *ctx, buckboost_cfg_t *cfg );

Application Init

Initialization device and set default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;
    buckboost_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 ----\r\n");

    //  Click initialization.

    buckboost_cfg_setup( &cfg );
    BUCKBOOST_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    buckboost_init( &buckboost, &cfg );

    buckboost_default_cfg( &buckboost );

Application Task

This is a example which demonstrates the use of Buck Boost Click board. Change output voltage from 2500 mV to 15000 mV every 5 seconds. All data logs write on usb uart for aproximetly every 5 sec.

void application_task ( void )
{
    log_printf(&logger, " Set Output Voltage of  2500 mV \r\n");
    log_printf(&logger, "--------------------------------\r\n");

    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    log_printf(&logger, " Set Output Voltage of  3300 mV \r\n");
    log_printf(&logger, "--------------------------------\r\n");
    buckboost_set_3300mv( &buckboost );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    log_printf(&logger, " Set Output Voltage of  6900 mV \r\n");
    log_printf(&logger, "--------------------------------\r\n");
    buckboost_set_6900mv( &buckboost );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    log_printf(&logger, " Set Output Voltage of  8200 mV \r\n");
    log_printf(&logger, "--------------------------------\r\n");
    buckboost_set_8200mv( &buckboost );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    log_printf(&logger, " Set Output Voltage of  12000 mV \r\n");
    log_printf(&logger, "--------------------------------\r\n");
    buckboost_set_12000mv( &buckboost );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    log_printf(&logger, " Set Output Voltage of  15000 mV \r\n");
    log_printf(&logger, "--------------------------------\r\n");
    buckboost_set_15000mv( &buckboost );
    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.
