Charger 30 Click

Charger 30 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.

• Type : I2C type

Software Support

Example Description

This example demonstrates the use of the Charger 30 Click board by reading and logging the charging status, input and battery voltage, current consumption, and fault diagnostics. The demo configures the default setup and then periodically polls for system status and fault information.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Charger30

Example Key Functions

• charger30_cfg_setup This function initializes Click configuration structure to initial values.

  void charger30_cfg_setup ( charger30_cfg_t *cfg );

• charger30_init This function initializes all necessary pins and peripherals used for this Click board.

  err_t charger30_init ( charger30_t *ctx, charger30_cfg_t *cfg );

• charger30_default_cfg This function executes a default configuration of Charger 30 Click board.

  err_t charger30_default_cfg ( charger30_t *ctx );

• charger30_read_status This function reads multiple status and monitoring registers and stores the values into the provided status structure.

  err_t charger30_read_status ( charger30_t *ctx, charger30_status_t *status );

Application Init

Initializes the logger and the Charger 30 Click driver and applies the default configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;  
    charger30_cfg_t charger30_cfg;  

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    charger30_cfg_setup( &charger30_cfg );
    CHARGER30_MAP_MIKROBUS( charger30_cfg, MIKROBUS_1 );
    if ( I2C_MASTER_ERROR == charger30_init( &charger30, &charger30_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    if ( CHARGER30_ERROR == charger30_default_cfg ( &charger30 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }
    
    log_info( &logger, " Application Task " );
}

Application Task

Periodically reads and logs charger status and fault registers along with voltage, current.

void application_task ( void )
{
    charger30_status_t status;
    if ( CHARGER30_OK == charger30_read_status ( &charger30, &status ) )
    {
        charger30_display_status ( status.status );
        charger30_display_fault ( status.fault );
        log_printf ( &logger, " VBAT: %u mV\r\n", status.vbat );
        log_printf ( &logger, " VSYS: %u mV\r\n", status.vsys );
        log_printf ( &logger, " NTC: %.1f %%\r\n", status.ntc );
        log_printf ( &logger, " VIN: %u mV\r\n", status.vin );
        log_printf ( &logger, " Ichg: %.1f mA\r\n", status.ichg );
        log_printf ( &logger, " Iin: %.1f mA\r\n", status.iin );
        log_printf ( &logger, " Iin_dpm: %u mA\r\n\n", status.iin_dpm );
    }
    Delay_ms ( 1000 );
}

Note

Ensure a valid power supply and a battery are connected for proper functionality.

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.
