Click library

• Author : MikroE Team
• Date : Dec 2019.
• Type : GPIO type

Software Support

We provide a library for the Charger13 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for Charger13 Click driver.

Standard key functions :

• Config Object Initialization function.

void charger13_cfg_setup ( charger13_cfg_t *cfg );

• Initialization function.

CHARGER13_RETVAL charger13_init ( charger13_t *ctx, charger13_cfg_t *cfg );

• Click Default Configuration function.

void charger13_default_cfg ( charger13_t *ctx );

Example key functions :

• This function enable battery charging by cleared to LOW state of the EN ( PWM ) pin of the Charger 13 click board.

void charger13_enable ( charger13_t *ctx );

• This function disable battery charging by sets to HIGH state of the EN ( PWM ) pin of the Charger 13 click board.

charger13_disable ( charger13_t *ctx );

• This function check if the battery is charging of the Charger 13 click board.

uint8_t charger13_check ( charger13_t *ctx );

Examples Description

This demo application charges the battery.

The demo application is composed of two sections :

Application Init

Initialization device.

void application_init ( void )
{
    log_cfg_t log_cfg;
    charger13_cfg_t cfg;

    /** 
     * 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 ----\r\n" );

    //  Click initialization.

    charger13_cfg_setup( &cfg );
    CHARGER13_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    charger13_init( &charger13, &cfg );

    Delay_100ms( );

    charger_flag = 2;
    enable_flag = 0;

    log_printf( &logger, "-------------------------\r\n" );
    log_printf( &logger, "      'E' : Enable       \r\n" );
    log_printf( &logger, "      'D' : Disable      \r\n" );
    log_printf( &logger, "-------------------------\r\n" );
    log_printf( &logger, "Charging Status : Disable\r\n" );
    log_printf( &logger, "-------------------------\r\n" );
    Delay_100ms( );
}
  

Application Task

This is an example which demonstrates the use of Charger 13 click board. This example shows the automatic control of the Charger 13 click, waits for valid user input and executes functions based on a set of valid commands and check the battery charge status. Results are being sent to the Usart Terminal where you can track their changes. All data logs on usb uart for approximately every 1 sec when the data value changes.

void application_task ( void )
{
    if ( enable_flag == 0 )
    {
        enable_flag = 1;
        charger13_enable( &charger13 );
        log_printf( &logger, "Charging Status : Enabled\r\n" );
        log_printf( &logger, "-------------------------\r\n" );
    }
    else if ( enable_flag == 1 )
    {
        enable_flag = 0;
        charger13_disable( &charger13 );
        log_printf( &logger, "Charging Status : Disable\r\n" );
        log_printf( &logger, "-------------------------\r\n" );
    }
    status_flag = charger13_check( &charger13 );

    if ( status_flag != charger_flag )
    {   
        charger_flag = charger13_check( &charger13 );

        if ( charger_flag == 0 )
        {
            log_printf( &logger, "   Battery is charging   \r\n" );
            log_printf( &logger, "-------------------------\r\n" );
        }
        else
        {
            log_printf( &logger, " Battery does not charge \r\n" );
            log_printf( &logger, "-------------------------\r\n" );
        }
    }    
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

• MikroSDK.Board
• MikroSDK.Log
• Click.Charger13

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. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
