Smart Buck Click

Smart Buck 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 : Dec 2019.
• Type : I2C type

Software Support

Example Description

This application reads voltage, current, and power from all available channels.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.SMARTBUCK

Example Key Functions

• smartbuck_cfg_setup Config Object Initialization function.

void smartbuck_cfg_setup ( smartbuck_cfg_t *cfg );

• smartbuck_init Initialization function.

err_t smartbuck_init ( smartbuck_t *ctx, smartbuck_cfg_t *cfg );

• smartbuck_default_cfg Click Default Configuration function.

void smartbuck_default_cfg ( smartbuck_t *ctx );

• smartbuck_send_cmd_PAC Function performs the desired command for PAC1934.

uint8_t smartbuck_send_cmd_PAC ( smartbuck_t *ctx, uint8_t command );

• smartbuck_get_data Function reads and calculates the voltage, current and power data from PAC1934 activated channels.

void smartbuck_get_data ( smartbuck_t *ctx,  float *voltage, float *current, float *power );

• smartbuck_block_read_PAC Function reads the desired number of bytes from the PAC1934 registers.

uint8_t smartbuck_block_read_PAC ( smartbuck_t *ctx, uint8_t reg_addr, uint8_t *data_out, uint8_t n_bytes );

Application Init

Initializes I2C interface and logger and peforms the Click default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;
    smartbuck_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.

    smartbuck_cfg_setup( &cfg );
    SMARTBUCK_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    smartbuck_init( &smartbuck, &cfg );
    smartbuck_default_cfg( &smartbuck );
}

Application Task

Sends command for updating data registers with new converted data, then waits 500ms and after that reads new data from data registers. In this way we can get voltage, current and power data from activated channels. Results are being logged on USB UART.

void application_task ( void )
{
    smartbuck_send_cmd_pac( &smartbuck, SMARTBUCK_REFRESH_V_CMND );
    Delay_ms ( 500 );
    smartbuck_get_data( &smartbuck, &voltage_res[ 0 ], &current_res[ 0 ], &power_res[ 0 ] );
    
    check_byte = 0x80;
    idx = 0;
    
    for ( cnt = 0; cnt < 4; cnt++ )
    {
        if ( ( smartbuck.enabled_chann & check_byte ) == 0 )
        {
            channel_log();
            
            log_printf( &logger, "U: %.2f V    ", voltage_res[ idx ] );
            log_printf( &logger, "I: %.2f mA    ", current_res[ idx ] );
            log_printf( &logger, "P: %.2f mW    ", power_res[ idx ] );
            
            idx++;
        }
        check_byte >>= 1;
    }
    
    log_printf( &logger, "\n");
}
 

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.
