Charger 16 Click

Charger 16 Click is a compact add-on board that represents a single-cell battery charger. This board features the LT1571, a constant-current/constant-voltage battery charger with preset voltage and termination flag from Analog Devices.

• Type : GPIO type

Software Support

We provide a library for the Charger16 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 Charger16 Click driver.

Standard key functions :

• charger16_cfg_setup Config Object Initialization function.

  void charger16_cfg_setup ( charger16_cfg_t *cfg );

• charger16_init Initialization function.

  err_t charger16_init ( charger16_t *ctx, charger16_cfg_t *cfg );

• charger16_default_cfg Click Default Configuration function.

  err_t charger16_default_cfg ( charger16_t *ctx );

Example key functions :

• charger16_enable_charging Charger 16 enable charging function.

  err_t charger16_enable_charging ( charger16_t *ctx );

• charger16_disable_charging Charger 16 disable charging function.

  err_t charger16_disable_charging ( charger16_t *ctx );

Example Description

This library contains API for the Charger 16 Click driver. This demo application shows use of a Charger 16 Click board™.

The demo application is composed of two sections :

Application Init

Initialization of GPIO module and log UART. After driver initialization the app set default settings.

void application_init ( void ) 
{
    log_cfg_t log_cfg;              /**< Logger config object. */
    charger16_cfg_t charger16_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.

    charger16_cfg_setup( &charger16_cfg );
    CHARGER16_MAP_MIKROBUS( charger16_cfg, MIKROBUS_1 );
    if ( charger16_init( &charger16, &charger16_cfg ) == DIGITAL_OUT_UNSUPPORTED_PIN ) 
    {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }
    charger16_default_cfg ( &charger16 );
    log_info( &logger, " Application Task " );
    Delay_ms ( 100 );
}

Application Task

This is an example that shows the use of an Charger 16 Click board™. The app turns the battery charge on and off every 10 seconds. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void ) 
{
    log_printf( &logger, "-----------------\r\n" );
    log_printf( &logger, " Enable charging \r\n" );
    charger16_enable_charging( &charger16 );
    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 );

    log_printf( &logger, "------------------\r\n" );
    log_printf( &logger, " Disable charging \r\n" );
    charger16_disable_charging( &charger16 );
    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 );
}

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.Charger16

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.
