Click library

  • Author : MikroE Team
  • Date : Dec 2019.
  • Type : I2C type

Software Support

We provide a library for the Charger2 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 Charger2 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void charger2_cfg_setup ( charger2_cfg_t *cfg );

  • Initialization function.

    CHARGER2_RETVAL charger2_init ( charger2_t ctx, charger2_cfg_t cfg );

  • Click Default Configuration function.

    void charger2_default_cfg ( charger2_t *ctx );

Example key functions :

  • This function writes one byte data to the register.

    uint8_t charger2_write_reg ( charger2_t *ctx, uint8_t register_address, uint8_t transfer_data );

  • This function reads the desired data from data registers and converts this data to the appropriate unit.

    uint8_t charger2_read_data ( charger2_t ctx, uint8_t data_mode, uint32_t data_out );

  • This function checks is conversion cycle for battery current, or for battery voltage and temperature, finished, and if is not, waits until one of this conversions be finished.

    uint8_t charger2_check_conv_cycle( charger2_t *ctx, uint8_t conv_mode );

Examples Description

This app charges the battery.

The demo application is composed of two sections :

Application Init

Initializes device.


void application_init ( void )
{
    log_cfg_t log_cfg;
    charger2_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.

    charger2_cfg_setup( &cfg );
    CHARGER2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    charger2_init( &charger2, &cfg );

    Delay_ms ( 500 );

    charger2_reset( &charger2, CHARGER2_RESET_COUNTER_MODE );
    Delay_ms ( 1000 );
    charger2_write_reg( &charger2, CHARGER2_REG_MODE, CHARGER2_AUTO_DETECT | CHARGER2_14_BITS_RESOLUTION | CHARGER2_OPERATING_MODE );
    log_printf( &logger, "Charger 2 is initialized \r\n" );
    log_printf( &logger, "------------------------------ \r\n" );
    Delay_ms ( 300 );
}

Application Task

Reads the all necessary information for the battery charging status and logs this results on UART. Repeats operation every second. The LED diodes are used to indicate the Vcc presence when this voltage is in operating range, and to show the charging status.


void application_task ( void )
{
    charger2_read_data( &charger2, CHARGER2_GAS_GAUGE_CHARGE_DATA, &battery_data );
    results_logger( &charger2 );
    charger2_read_data( &charger2, CHARGER2_CONV_NUMBER, &battery_data );
    results_logger( &charger2 );
    charger2_read_data( &charger2, CHARGER2_SHUNT_VOLTAGE, &battery_data );
    results_logger( &charger2 );
    charger2_read_data( &charger2, CHARGER2_BATTERY_VOLTAGE, &battery_data );
    results_logger( &charger2 );
    charger2_read_data( &charger2, CHARGER2_TEMPERATURE, &battery_data );
    results_logger( &charger2 );
    charger2_read_data( &charger2, CHARGER2_BATTERY_CURRENT, &battery_data );
    results_logger( &charger2 );

    log_printf( &logger, "------------------------------ \r\n" );
    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.Charger2

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.
