Buck 14 Click

Buck 14 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 app enables usage of high-efficiency step-down converter.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Buck14

Example Key Functions

• buck14_cfg_setup Config Object Initialization function.

void buck14_cfg_setup ( buck14_cfg_t *cfg );

• buck14_init Initialization function.

err_t buck14_init ( buck14_t *ctx, buck14_cfg_t *cfg );

Application Init

Configure device.

void application_init ( void )
{
    log_cfg_t log_cfg;
    buck14_cfg_t cfg;
    uint8_t write_data;
    uint8_t status_data;

    /** 
     * 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.
     */

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

Note

When you send data you should send LSB first. Device input V should be beetween 4.5 - 14 V. Device output V could be from 0.5 - 5 V deepending from limits you set currently it is set to 1V.

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.
