Charger 8 Click

Charger 8 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.

• MikroSDK.Log
• Click.Charger8

Example Key Functions

• charger8_cfg_setup Config Object Initialization function.

void charger8_cfg_setup ( charger8_cfg_t *cfg );

• charger8_init Initialization function.

err_t charger8_init ( charger8_t *ctx, charger8_cfg_t *cfg );

• charger8_default_cfg Click Default Configuration function.

void charger8_default_cfg ( charger8_t *ctx );

• charger8_get_temperature Functions for read Temperature of the chip.

float charger8_get_temperature( charger8_t *ctx );

• charger8_get_capacity Function for reads the current capacity of the battery.

uint16_t charger8_get_capacity( charger8_t *ctx );

• charger8_get_status Function for reads the Status register.

uint16_t charger8_get_status( charger8_t *ctx );

Application Init

Initialization driver init, enable moduele and default configuration, disable ALERT and USB suspand mode and sets max battery capacity

void application_init ( void )
{
    log_cfg_t log_cfg;
    charger8_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.

    charger8_cfg_setup( &cfg );
    CHARGER8_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    charger8_init( &charger8, &cfg );

    charger8_enable( &charger8, CHARGER8_CHARGER_ENABLE );
    charger8_default_cfg( &charger8 );
    charger8_reset( &charger8 );
    charger8_set_alert( &charger8, CHARGER8_ALERT_DISABLE );
    charger8_set_usb_suspend( &charger8, CHARGER8_USB_SUSPAND_MODE_DISABLE );
    charger8_set_max_battery_capacity( 2000 );
    log_printf( &logger, " --- Charger - Start measurement --- \r\n" );
    Delay_ms ( 1000 );
}

Application Task

Reads battery diagnostics and this data logs to USBUART every 1500 ms.

void application_task ( void )
{
    //  Task implementation.

    float temperature;
    float current;
    float voltage;
    uint8_t soc;
    uint16_t capacity;
    
    log_printf( &logger, " - Battery diagnostics - \r\n" );
    
    temperature = charger8_get_temperature( &charger8 );
    log_printf( &logger, " - Temperature : %f C\r\n", temperature );
    
    current = charger8_get_current( &charger8 );
    log_printf( &logger, " - Current : %f mA\r\n", current);
    
    voltage = charger8_get_voltage( &charger8 );
    log_printf( &logger, " - Voltage : %f mV\r\n", voltage);
    
    capacity = charger8_get_capacity( &charger8 );
    log_printf( &logger, " - Capacity : %d mAh\r\n", capacity );
    
    soc = charger8_get_soc( &charger8 );
    log_printf( &logger, " - SOC : %d %%\r\n", soc );
    
    log_printf( &logger, " -------------------------- \r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 500 );
}

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.
