Charger 2 Click

Charger 2 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.

• Type : I2C type

Software Support

Example Description

This app charges the battery.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Charger2

Example Key Functions

• charger2_cfg_setup Config Object Initialization function.

void charger2_cfg_setup ( charger2_cfg_t *cfg );

• charger2_init Initialization function.

err_t charger2_init ( charger2_t *ctx, charger2_cfg_t *cfg );

• charger2_default_cfg Click Default Configuration function.

void charger2_default_cfg ( charger2_t *ctx );

• charger2_write_reg 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 );

• charger2_read_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 );

• charger2_check_conv_cycle 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 );

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 );
}

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.
