ECG Click

ECG 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.

Example Description

This example demonstrates the use of ECG Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Ecg

Example Key Functions

• ecg_cfg_setup Config Object Initialization function.

void ecg_cfg_setup ( ecg_cfg_t *cfg );

• ecg_init Initialization function.

err_t ecg_init ( ecg_t *ctx, ecg_cfg_t *cfg );

• ecg_default_cfg Click Default Configuration function.

void ecg_default_cfg ( ecg_t *ctx );

• ecg_generic_read This function read ADC data.

ecg_data_t ecg_generic_read ( ecg_t *ctx );

• ecg_default_cfg This function executes default configuration for ECG Click.

void ecg_default_cfg ( ecg_t *ctx );

• ecg_init This function initializes all necessary pins and peripherals used for this Click.

err_t ecg_init ( ecg_t *ctx, ecg_cfg_t *cfg );

Application Init

Initializes Click board.

void application_init ( void )
{
    log_cfg_t log_cfg;
    ecg_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.

    ecg_cfg_setup( &cfg );
    Delay_ms ( 200 );
    ECG_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ecg_init( &ecg, &cfg );
    Delay_ms ( 200 );

    time_read = 0;
}

Application Task

Reads ADC sends results on serial plotter.

void application_task ( void )
{
    time_read++;
    read_adc = ecg_generic_read( &ecg );
    plot_res( read_adc , time_read);

    Delay_ms ( 5 );
}

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.
