Charger 19 Click

Charger 19 Click is a compact add-on board that contains a battery charger. This board features the nPM1100, an integrated power management IC from Nordic Semiconductor. It has a highly efficient DC/DC buck regulator with automatic selection between hysteretic and PWM modes.

Software Support

We provide a library for the Charger 19 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for Charger 19 Click driver.

Standard key functions :

• charger19_cfg_setup Config Object Initialization function.

  void charger19_cfg_setup ( charger19_cfg_t *cfg );

• charger19_init Initialization function.

  err_t charger19_init ( charger19_t *ctx, charger19_cfg_t *cfg );

• charger19_default_cfg Click Default Configuration function.

  err_t charger19_default_cfg ( charger19_t *ctx );

Example key functions :

• charger19_set_vout Charger 19 set output voltage function.

  err_t charger19_set_vout ( charger19_t *ctx, uint8_t vout_sel );

• charger19_set_ship_mode Charger 19 set Ship mode function.

  void charger19_set_ship_mode ( charger19_t *ctx, uint8_t ship_sel );

• charger19_get_vbat Charger 19 get battery voltage function.

  err_t charger19_get_vbat ( charger19_t *ctx, float *vbat );

Example Description

This example demonstrates the use of Charger 19 Click board by enabling the device and then reading and displaying the battery voltage.

The demo application is composed of two sections :

Application Init

Initializes the driver and enables the device, sets the output voltage to 3 V.

void application_init ( void )
{
    log_cfg_t log_cfg;              /**< Logger config object. */
    charger19_cfg_t charger19_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.
    charger19_cfg_setup( &charger19_cfg );
    CHARGER19_MAP_MIKROBUS( charger19_cfg, MIKROBUS_1 );
    if ( ADC_ERROR == charger19_init( &charger19, &charger19_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    if ( CHARGER19_ERROR == charger19_default_cfg ( &charger19 ) )
    {
        log_error( &logger, " Default configuration." );
        for ( ; ; );
    }

    log_info( &logger, " Application Task " );
}

Application Task

Tracking charging status, reading battery voltage.

void application_task ( void ) 
{
    float voltage = 0;
    if ( CHARGER19_OK == charger19_get_vbat ( &charger19, &voltage ) ) 
    {
        log_printf( &logger, " Battery Voltage : %.3f[V]\r\n\n", voltage );
        Delay_ms ( 1000 );
    }
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.Charger19

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
