Boost 12 Click

Boost 12 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.

• Date : Dec 2025.
• Type : PWM type

Software Support

Example Description

This example demonstrates the use of the Boost 12 Click board, changing the output voltage by generating a PWM signal whose duty cycle is gradually increased and decreased between 10% and 100%.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Boost12

Example Key Functions

• boost12_cfg_setup This function initializes Click configuration structure to initial values.

  void boost12_cfg_setup ( boost12_cfg_t *cfg );

• boost12_init This function initializes all necessary pins and peripherals used for this Click board.

  err_t boost12_init ( boost12_t *ctx, boost12_cfg_t *cfg );

• boost12_default_cfg This function executes a default configuration of Boost 12 Click board.

  err_t boost12_default_cfg ( boost12_t *ctx );

• boost12_pwm_start This function starts the PWM module output.

  err_t boost12_pwm_start ( boost12_t *ctx );

• boost12_set_duty_cycle This function sets the PWM duty cycle in percentages ( Range[ 0..1 ] ).

  err_t boost12_set_duty_cycle ( boost12_t *ctx, float duty_cycle );

Application Init

Initializes the logger and Boost 12 Click driver and applies the default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  
    boost12_cfg_t boost12_cfg;  

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    boost12_cfg_setup( &boost12_cfg );
    BOOST12_MAP_MIKROBUS( boost12_cfg, MIKROBUS_1 );
    if ( PWM_ERROR == boost12_init( &boost12, &boost12_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( BOOST12_ERROR == boost12_default_cfg ( &boost12 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Adjusts the PWM duty cycle in 1% steps, logs the current value, and smoothly oscillates the duty between minimum and maximum levels.

void application_task ( void )
{
    static int8_t duty_cnt = 10;
    static int8_t duty_inc = 1;
    float duty = duty_cnt / 100.0;
    
    boost12_set_duty_cycle ( &boost12, duty );
    log_printf( &logger, "> Duty: %d%%\r\n", ( int16_t ) duty_cnt );
    
    duty_cnt += duty_inc;
    if ( ( duty_cnt < 10 ) || ( duty_cnt > 100 ) ) 
    {
        duty_inc = -duty_inc;
        duty_cnt += duty_inc;
        duty_cnt += duty_inc;
    }
    Delay_ms ( 1000 );
}

Note

The higher the duty cycle the higher the output voltage. The output voltage range is from VIN to 12V.

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.
