Charger 25 Click

Charger 25 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 example demonstrates the use of Charger 25 Click board™ by enabling battery charging and displaying battery voltage and charging status.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Charger25

Example Key Functions

• charger25_cfg_setup Config Object Initialization function.

void charger25_cfg_setup ( charger25_cfg_t *cfg );

• charger25_init Initialization function.

err_t charger25_init ( charger25_t *ctx, charger25_cfg_t *cfg );

• charger25_default_cfg Click Default Configuration function.

err_t charger25_default_cfg ( charger25_t *ctx );

• charger25_get_vbat Charger 25 get VBAT function.

err_t charger25_get_vbat ( charger25_t *ctx, uint16_t *vbat );

• charger25_get_status Charger 25 get charging status function.

err_t charger25_get_status ( charger25_t *ctx, charger25_status_t *status );

• charger25_get_vbat_lim Charger 25 get battery voltage limit function.

err_t charger25_get_vbat_lim ( charger25_t *ctx, uint16_t *vtg_lim );

Application Init

Initialization of I2C module and log UART. After driver initialization, the app executes a default configuration.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    charger25_cfg_t charger25_cfg;  /**< Click config object. */

    /** 
     * 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.
    charger25_cfg_setup( &charger25_cfg );
    CHARGER25_MAP_MIKROBUS( charger25_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == charger25_init( &charger25, &charger25_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( CHARGER25_ERROR == charger25_default_cfg ( &charger25 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
    log_printf( &logger, " ----------------\r\n" );
    Delay_ms ( 100 );
}

Application Task

The demo application reads and displays the results of the battery voltage, minimal system voltage, battery voltage limit and charging status. Results are being sent to the UART Terminal, where you can track their changes.

void application_task ( void ) 
{
    static uint16_t vtg_data = 0;
    if ( CHARGER25_OK == charger25_get_status ( &charger25, &status ) )
    {
        charger25_display_status( );
    }
    Delay_ms ( 100 );
    
    if ( CHARGER25_OK == charger25_get_vbat( &charger25, &vtg_data ) )
    {
        log_printf( &logger, " VBAT: %u [mV]\r\n", vtg_data );
    }
    Delay_ms ( 100 );
    
    if ( CHARGER25_OK == charger25_get_vsys_min( &charger25, &vtg_data ) )
    {
        log_printf( &logger, " VMIN: %u [mV]\r\n", vtg_data );
    }
    Delay_ms ( 100 );
    
    if ( CHARGER25_OK == charger25_get_vbat_lim( &charger25, &vtg_data ) )
    {
        log_printf( &logger, " VLIM: %u [mV]\r\n", vtg_data );
    }
    log_printf( &logger, " ----------------\r\n" );
    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.
