Step Up Click

Step Up 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.

Click Library

• Author : MikroE Team
• Date : Jan 2020.
• Type : SPI type

Software Support

Example Description

This application enables usage of DC-DC step-up (boost) regulator.>

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.StepUp

Example Key Functions

• stepup_cfg_setup Config Object Initialization function.

void stepup_cfg_setup ( stepup_cfg_t *cfg );

• stepup_init Initialization function.

err_t stepup_init ( stepup_t *ctx, stepup_cfg_t *cfg );

• stepup_default_cfg Click Default Configuration function.

void stepup_default_cfg ( stepup_t *ctx );

• stepup_get_percent This function calculates ouput value in percent.

float stepup_get_percent ( uint16_t out_value );

• stepup_en_set This function sets the EN pin state.

void stepup_en_set ( stepup_t *ctx, uint8_t pin_state );

• stepup_set_out This function sets output value.

uint8_t stepup_set_out ( stepup_t *ctx, uint16_t out_value );

Application Init

Initializes SPI driver, sets config word, initializes and configures the device

void application_init ( void )
{
    log_cfg_t log_cfg;
    stepup_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.

    stepup_cfg_setup( &cfg );
    STEPUP_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    stepup_init( &stepup, &cfg );
    
    stepup_default_cfg( &stepup );

    Delay_ms ( 100 );
    log_info( &logger, "Application Task" );
}

Application Task

Sets 3 different boost precentage value to device, value changes every 10 seconds.

void application_task ( void )
{
    log_info( &logger, "Setting DAC boost to 10%%" );
    stepup_set_percentage( &stepup, 10 );
    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_info( &logger, "Setting DAC boost to 60%%" );
    stepup_set_percentage( &stepup, 60 );
    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_info( &logger, "Setting DAC boost to 30%%" );
    stepup_set_percentage( &stepup, 30 );
    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 );
}

Note

Additional Functions :

stepup_logPercent() - calls 'stepup_getPercent()' function to get output value in expressed as percentage and logs that value.

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.
