Charger 23 Click

Charger 23 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.

Software Support

Example Description

This example demonstrates the use of Charger 23 Click board by enabling the device and then reading and displaying the charger status.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Charger23

Example Key Functions

• charger23_cfg_setup Config Object Initialization function.

void charger23_cfg_setup ( charger23_cfg_t *cfg );

• charger23_init Initialization function.

err_t charger23_init ( charger23_t *ctx, charger23_cfg_t *cfg );

• charger23_enable_device This function enables the device by setting the EN pin to HIGH logic state.

void charger23_enable_device ( charger23_t *ctx );

• charger23_disable_device This function disables the device by setting the EN pin to LOW logic state.

void charger23_disable_device ( charger23_t *ctx );

• charger23_get_charger_state This function returns the charger state.

uint8_t charger23_get_charger_state ( charger23_t *ctx );

Application Init

Initializes the driver and enables the device.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    charger23_cfg_t charger23_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.
    charger23_cfg_setup( &charger23_cfg );
    CHARGER23_MAP_MIKROBUS( charger23_cfg, MIKROBUS_POSITION_CHARGER23 );
    if ( DIGITAL_OUT_UNSUPPORTED_PIN == charger23_init( &charger23, &charger23_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    charger23_enable_device ( &charger23 );
    log_info( &logger, " Application Task " );
}

Application Task

Reads the charger state and displays it on the USB UART on change.

void application_task ( void )
{
    static uint8_t chg_state_old = CHARGER23_STATE_UNKNOWN;
    uint8_t chg_state = charger23_get_charger_state ( &charger23 );
    if ( chg_state_old != chg_state )
    {
        chg_state_old = chg_state;
        log_printf( &logger, "\r\n Charger state: " );
        switch ( chg_state )
        {
            case CHARGER23_STATE_IDLE:
            {
                log_printf( &logger, "Charge completed with no fault (Inhibit) or Standby\r\n" );
                break;
            }
            case CHARGER23_STATE_CHARGING:
            {
                log_printf( &logger, "Charging in one of the three modes\r\n" );
                break;
            }
            case CHARGER23_STATE_FAULT:
            {
                log_printf( &logger, "Fault\r\n" );
                break;
            }
            default:
            {
                log_printf( &logger, "Unknown\r\n" );
                break;
            }
        }
        Delay_ms ( 100 );
    }
}

Note

Depending on the CURR SEL onboard jumper position this Click board is able to charge batteries of 250mAh or 500mAh rated capacity.

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.
