Charger 24 Click

Charger 24 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 : Stefan Filipovic
• Date : Apr 2025.
• Type : GPIO type

Software Support

Example Description

This example demonstrates the use of the Charger 24 Click board. The application initializes the device, enables battery charging, and continuously monitors the charging and USB power status. It displays whether the battery is currently charging, fully charged, or if no input is detected, as well as whether the USB power is valid.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Charger24

Example Key Functions

• charger24_cfg_setup This function initializes Click configuration structure to initial values.

  void charger24_cfg_setup ( charger24_cfg_t *cfg );

• charger24_init This function initializes all necessary pins and peripherals used for this Click board.

  err_t charger24_init ( charger24_t *ctx, charger24_cfg_t *cfg );

• charger24_enable_charging This function enables battery charging on the Charger 24 Click board.

  void charger24_enable_charging ( charger24_t *ctx );

• charger24_get_iok_pin This function returns the logic state of the IOK pin.

  uint8_t charger24_get_iok_pin ( charger24_t *ctx );

• charger24_get_status This function checks the battery charging status by polling the STAT pin.

  uint8_t charger24_get_status ( charger24_t *ctx );

Application Init

Initializes the logger and the Charger 24 Click driver and enables charging while disabling boost mode.

void application_init ( void )
{
    log_cfg_t log_cfg;  
    charger24_cfg_t charger24_cfg;  

    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, " Application Init " );
 
    // Click initialization.
    charger24_cfg_setup( &charger24_cfg );
    CHARGER24_MAP_MIKROBUS( charger24_cfg, MIKROBUS_POSITION_CHARGER24 );
    if ( DIGITAL_OUT_UNSUPPORTED_PIN == charger24_init( &charger24, &charger24_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
 
    charger24_disable_boost ( &charger24 );
    charger24_enable_charging ( &charger24 );
    
    log_info( &logger, " Application Task " );
}

Application Task

Periodically reads and logs the charging and USB power status.

void application_task ( void )
{
    uint8_t status = charger24_get_status ( &charger24 );
    
    log_printf( &logger, "\r\n Charging status: " );
    switch ( status )
    {
        case CHARGER24_STATE_NO_INPUT:
        {
            log_printf( &logger, "No input or fault\r\n" );
            break;
        }
        case CHARGER24_STATE_CHARGING:
        {
            log_printf( &logger, "Trickle, precharge, fast charge\r\n" );
            break;
        }
        case CHARGER24_STATE_CHARGE_DONE:
        {
            log_printf( &logger, "Top-off and done\r\n" );
            break;
        }
        default:
        {
            log_printf( &logger, "Unknown\r\n" );
            break;
        }
    }
 
    log_printf( &logger, " USB status: " );
    if ( charger24_get_iok_pin( &charger24 ) )
    {
        log_printf( &logger, "No power\r\n" );
    }
    else
    {
        log_printf( &logger, "Power good\r\n" );
    }
}

Note

Ensure a valid USB input source and battery are connected to observe status transitions.

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.
