POWER BANK Click

PowerBank Click is a USB charging expansion board which can be used for creating power bank devices or adding charging option to your device. For battery charging management this board uses MP2632B a highly integrated 3A Lu-ion and Li-polymer battery charger from Microchip. In addition to battery charger PowerBank Click also has a MCP3221 analog to digital converter, which is serving for monitoring battery voltage over I2C interface.

Click library

  • Author : MikroE Team
  • Date : Feb 2020.
  • Type : I2C type

Software Support

We provide a library for the PowerBank 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 PowerBank Click driver.

Standard key functions :

  • Config Object Initialization function.

    void powerbank_cfg_setup ( powerbank_cfg_t *cfg );

  • Initialization function.

    POWERBANK_RETVAL powerbank_init ( powerbank_t ctx, powerbank_cfg_t cfg );

Example key functions :

  • Read data function

    uint16_t powerbank_read_data ( powerbank_t *ctx );

  • Read voltage function

    uint16_t powerbank_read_voltage ( powerbank_t *ctx, uint16_t v_ref );

Examples Description

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

The demo application is composed of two sections :

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 );
}  

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.PowerBank

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.
