BUCK 7 Click

BUCK 7 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 demo application controls the voltage at the output using the BUCK 7 Click.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.BUCK7

Example Key Functions

• buck7_cfg_setup Config Object Initialization function.

void buck7_cfg_setup ( buck7_cfg_t *cfg );

• buck7_init Initialization function.

err_t buck7_init ( buck7_t *ctx, buck7_cfg_t *cfg );

• buck7_default_cfg Click Default Configuration function.

void buck7_default_cfg ( buck7_t *ctx );

• buck7_set_output_voltage Function for settings output voltage.

void buck7_set_output_voltage ( buck7_t *ctx, uint16_t voltage );

• buck7_enable Function for enable chip.

void buck7_enable( buck7_t *ctx );

• buck7_set_mode Function for settings chip mode.

void buck7_set_mode( buck7_t *ctx, uint8_t mode );

Application Init

Initializes Driver init, reset chip, enable chip and set mode

void application_init ( void )
{
    log_cfg_t log_cfg;
    buck7_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.

    buck7_cfg_setup( &cfg );
    BUCK7_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    buck7_init( &buck7, &cfg );

    buck7_enable( &buck7 );
    buck7_set_mode( &buck7, BUCK7_MODE_PWM );
}

Application Task

Sets output voltage to 5V, 10V, 15V, 20V, 25V every 3 seconds. It is necessary to set the input voltage on 2.7V + maximum output voltage.

void application_task ( )
{
    buck7_set_output_voltage( &buck7, BUCK7_OUT_VOLTAGE_5V );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    buck7_set_output_voltage( &buck7, BUCK7_OUT_VOLTAGE_10V );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    buck7_set_output_voltage( &buck7, BUCK7_OUT_VOLTAGE_15V );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    buck7_set_output_voltage( &buck7, BUCK7_OUT_VOLTAGE_20V );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    buck7_set_output_voltage( &buck7, BUCK7_OUT_VOLTAGE_25V );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    buck7_set_output_voltage( &buck7, BUCK7_OUT_VOLTAGE_20V );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    buck7_set_output_voltage( &buck7, BUCK7_OUT_VOLTAGE_15V );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    buck7_set_output_voltage( &buck7, 0x0BB8 ); /* 10 V */
    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.
