Ecg 6 Click

Ecg 6 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

ECG 6 Click contain integrated electrocardiogram, pulse oximeter, heart rate monitor sensor module.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Ecg6

Example Key Functions

• ecg6_cfg_setup Config Object Initialization function.

void ecg6_cfg_setup ( ecg6_cfg_t *cfg );

• ecg6_init Initialization function.

err_t ecg6_init ( ecg6_t *ctx, ecg6_cfg_t *cfg );

• ecg6_default_cfg Click Default Configuration function.

void ecg6_default_cfg ( ecg6_t *ctx );

• ecg6_get_sample_data This function gets one sample from FIFO.

void ecg6_get_sample_data ( ecg6_t *ctx, ecg6_element_t *element, uint8_t num_sample );

• plot_ecg_data Sends ECG sensor data to SerialPlot.

static void plot_ecg_data (  uint32_t ecg_data  );

• plot_ppg_data Sends PPG sensor data to SerialPlot.

static void plot_ppg_data (  uint32_t ir_data, uint32_t red_data  );

Application Init

Initialize I2C module and all necessary pins. Checking communication accuracy and running default configuration for measurement.

void application_init ( void )
{
    log_cfg_t log_cfg;
    ecg6_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.

    ecg6_cfg_setup( &cfg );
    ECG6_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ecg6_init( &ecg6, &cfg );
    
    Delay_ms ( 1000 );
    
    DEMO_EXAMPLE = PPG_EXAMPLE;
   
    // Dummy read
    ecg6_check_path_id( &ecg6 );
    Delay_ms ( 100 );
    
    device_check = ecg6_check_path_id( &ecg6 );
    
    if ( device_check != 0 )
    {
       log_printf( &logger, " -- > Device ERROR!!! \r\n" );
       for ( ; ; );
    }
    log_printf( &logger, " -- > Device OK!!! \r\n" );

    if ( DEMO_EXAMPLE == ECG_EXAMPLE )
    {
        ecg6_default_cfg( &ecg6 );
    }
    else
    {
        ecg6_ppg_default_config( &ecg6 );
    }

    log_printf( &logger, " ---- Configuration done ----- \r\n" );
    Delay_ms ( 1000 );

    time_cnt = 0;
}

Application Task

Measures an ECG signal or PPG sensor and draws a graph on a SerialPlot

void application_task ( void )
{
    ecg6_element_t sample;
    
    if ( ecg6_int_pin_state(&ecg6) == 0 ) {
        
        ecg6_get_sample_data( &ecg6, &sample, 0x00 );
    
        if ( DEMO_EXAMPLE == ECG_EXAMPLE )
        {
            plot_ecg_data( sample.element_1 );
        }
        
        else
        {
            plot_ppg_data( sample.element_1, sample.element_2 );
        }
    }
}

Note

When using ECG measurement - PPG measurement must be switched off ... Drawing speeds vary for PPG and ECG sensor.

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.
