POWER BANK Click

PowerBank 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 is an example which demonstrates the usage of Power Bank Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.PowerBank

Example Key Functions

• powerbank_cfg_setup Config Object Initialization function.

void powerbank_cfg_setup ( powerbank_cfg_t *cfg );

• powerbank_init Initialization function.

err_t powerbank_init ( powerbank_t *ctx, powerbank_cfg_t *cfg );

• powerbank_read_data Read data function.

uint16_t powerbank_read_data ( powerbank_t *ctx );

• powerbank_read_voltage Read voltage function.

uint16_t powerbank_read_voltage ( powerbank_t *ctx, uint16_t v_ref );

Application Init

Initalizes I2C driver and makes an initial log.

void application_init ( void )
{
    log_cfg_t log_cfg;
    powerbank_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 ----" );

    //  Click initialization.

    powerbank_cfg_setup( &cfg );
    POWERBANK_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    powerbank_init( &powerbank, &cfg );

    Delay_ms ( 100 );
    log_printf( &logger, "------------------------\r\n" );
    log_printf( &logger, "     PowerBank Click    \r\n" );
    log_printf( &logger, "------------------------\r\n" );
}

Application Task

This example shows the capabilities of the PowerBank Click by measuring voltage of the connected battery. In order to get correct calculations user should change "v_ref" value to his own power supply voltage.

void application_task ( void )
{
    uint16_t voltage;
    uint16_t v_ref = 5075;

    voltage = powerbank_read_voltage( &powerbank, v_ref );
    log_printf( &logger, "Battery voltage: %d mV\r\n", voltage );
    
    log_printf( &logger, "------------------------\r\n" );
    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.
