Current 2 Click

Current 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.

Click Library

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

Software Support

Example Description

This application measures current.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Current2

Example Key Functions

• current2_cfg_setup Config Object Initialization function.

void current2_cfg_setup ( current2_cfg_t *cfg );

• current2_init Initialization function.

err_t current2_init ( current2_t *ctx, current2_cfg_t *cfg );

• current2_get_adc Get ADC function.

uint16_t current2_get_adc( current2_t *ctx );

• current2_get_average_adc Get Averaged ADC function.

uint16_t current2_get_average_adc( current2_t *ctx, uint8_t n_samp );

• current2_get_current Get Current function.

uint16_t current2_get_current( current2_t *ctx, uint8_t n_sample );

Application Init

Initializes SPI interface in Mode 0

void application_init ( void )
{
    log_cfg_t log_cfg;
    current2_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.

    current2_cfg_setup( &cfg );
    CURRENT2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    current2_init( &current, &cfg );
    Delay_ms ( 300 );
    log_printf( &logger, "Current 2 is initialized \r\n \r\n" );
}

Application Task

Reads the current averaged result of 20 samples and gets this result in a proper value [mA]. Repeats the current reading every 500ms.

void application_task ( void )
{
    uint16_t tmp;

    tmp = current2_get_current( &current, 20 );

    log_printf( &logger, "Current : %d mA \r\n", tmp );

    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.
