Click library

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

Software Support

We provide a library for the Current3 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 Current3 Click driver.

Standard key functions :

  • current3_cfg_setup Config Object Initialization function.

    void current3_cfg_setup ( current3_cfg_t *cfg ); 
  • current3_init Initialization function.

    err_t current3_init ( current3_t *ctx, current3_cfg_t *cfg );
  • current3_default_cfg Click Default Configuration function.

    void current3_default_cfg ( current3_t *ctx );

Example key functions :

  • current3_get_temperature The function get the temperature by read multiple data bytes from a group of contiguous registers

    float current3_get_temperature ( current3_t *ctx, uint8_t temp_sel );
  • current3_get_source_voltage The function source voltage registers store the voltage measured at the SENSE+ pin

    float current3_get_source_voltage ( current3_t *ctx );
  • current3_get_current The function current measurement measure the direction of current flow ( from SENSE+ to SENSE- or from SENSE- to SENSE+ )

    float current3_get_current ( current3_t *ctx );

Examples Description

Current 3 Click can be used to measure current ranging up to 8000mA, and display temperature, voltage and current data - using I2C comunication.

The demo application is composed of two sections :

Application Init

Initialization driver enables - I2C, check communication and set sense sampling configuration, also write log.


void application_init ( void )
{
    log_cfg_t log_cfg;
    current3_cfg_t cfg;
    uint8_t read_data;

    /** 
     * 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.

    current3_cfg_setup( &cfg );
    CURRENT3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    current3_init( &current3, &cfg );

    Delay_ms ( 100 );
    log_printf( &logger, "     Driver init. done     \r\n" );
    log_printf( &logger, "---------------------------\r\n" );

    current3_generic_read( &current3, CURRENT3_REG_PRODUCT_ID, &read_data, 1 );
    if (  read_data == CURRENT3_DEV_ID )
    {
        log_printf( &logger, "     Communication OK      \r\n" );
        log_printf( &logger, "---------------------------\r\n" );
    }
    else
    {
        log_printf( &logger, "    Communication ERROR    \r\n" );
        log_printf( &logger, "     Reset the device      \r\n" );
        log_printf( &logger, "---------------------------\r\n" );
        for ( ; ; );
    }

    current3_default_cfg( &current3, sense_cfg_data );
}

Application Task

This is an example which demonstrates the use of Current 3 Click board. Current 3 Click board can be used to measure current ranging up to 8000mA, and display temperature, voltage and current data. All data logs write on USB uart changes for every 2 sec.


void application_task ( void )
{
    temperature = current3_get_temperature( &current3, CURRENT3_TEMP_INTERNAL_DIODE );
    log_printf( &logger, " Temperature = %.2f C\r\n", temperature );

    voltage = current3_get_source_voltage( &current3 );
    log_printf( &logger, " Voltage     = %.2f V\r\n", voltage );

    current = current3_get_current( &current3 );
    log_printf( &logger, " Current     = %.2f mA\r\n", current );
    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.Current3

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.

BATT Boost Click is a compact add-on board that expands a coin battery cell's lifetime and current capability, like the CR2032 and lithium thionyl batteries. This board features the NBM5100A, a coin-cell battery life booster with adaptive power optimization from Nexperia. It is a battery energy management device designed to maximize usable capacity from non-rechargeable, primary batteries when used in low-voltage, low-power applications requiring burst current loads. The devices overcome voltage drop and battery life limitations associated with extracting high pulse currents.
