Charger 18 Click

Charger 18 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 18 Click board by controlling the status of the charger as well as the LDO and BUCK regulators.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Charger18

Example Key Functions

• charger18_cfg_setup Config Object Initialization function.

void charger18_cfg_setup ( charger18_cfg_t *cfg );

• charger18_init Initialization function.

err_t charger18_init ( charger18_t *ctx, charger18_cfg_t *cfg );

• charger18_buck_control This function controls the buck regulator enable state of Charger 18 Click board.

void charger18_buck_control ( charger18_t *ctx, uint8_t state ); 

• charger18_ldo_control This function controls the low dropout (LDO) regulator enable state of Charger 18 Click board.

void charger18_ldo_control ( charger18_t *ctx, uint8_t state );

• charger18_suspend_control This function controls the suspend charging mode state of Charger 18 Click board.

void charger18_suspend_control ( charger18_t *ctx, uint8_t state ); 

Application Init

Initializes the driver and enables the chip with the charger, LDO and BUCK regulators disabled.

void application_init ( void )
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    charger18_cfg_t charger18_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.
    charger18_cfg_setup( &charger18_cfg );
    CHARGER18_MAP_MIKROBUS( charger18_cfg, MIKROBUS_1 );
    if ( DIGITAL_OUT_UNSUPPORTED_PIN == charger18_init( &charger18, &charger18_cfg ) ) 
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }
    
    charger18_power_control( &charger18, CHARGER18_CONTROL_ENABLE );
    log_printf( &logger, " POWER   : ON\r\n" );
    charger18_suspend_control( &charger18, CHARGER18_CONTROL_ENABLE );
    log_printf( &logger, " CHARGER : OFF\r\n" );
    charger18_buck_control( &charger18, CHARGER18_CONTROL_DISABLE );
    log_printf( &logger, " BUCK    : OFF\r\n" );
    charger18_ldo_control( &charger18, CHARGER18_CONTROL_DISABLE );
    log_printf( &logger, " LDO     : OFF\r\n" );
    
    log_info( &logger, " Application Task " );
}

Application Task

This function enables the charger, BUCK and LDO in the span of 25 seconds, and displays the status of each feature on the USB UART.

void application_task ( void )
{
    charger18_suspend_control( &charger18, CHARGER18_CONTROL_DISABLE );
    log_printf( &logger, " CHARGER : ON\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    charger18_suspend_control( &charger18, CHARGER18_CONTROL_ENABLE );
    log_printf( &logger, " CHARGER : OFF\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    charger18_buck_control( &charger18, CHARGER18_CONTROL_ENABLE );
    log_printf( &logger, " BUCK    : ON\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    charger18_buck_control( &charger18, CHARGER18_CONTROL_DISABLE );
    log_printf( &logger, " BUCK    : OFF\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    charger18_ldo_control( &charger18, CHARGER18_CONTROL_ENABLE );
    log_printf( &logger, " LDO     : ON\r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    charger18_ldo_control( &charger18, CHARGER18_CONTROL_DISABLE );
    log_printf( &logger, " LDO     : OFF\r\n\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    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.
