ECG 5 Click

ECG 5 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 is an example which demonstrates the use of ECG 5 Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.ECG5

Example Key Functions

• ecg5_cfg_setup Config Object Initialization function.

void ecg5_cfg_setup ( ecg5_cfg_t *cfg );

• ecg5_init Initialization function.

err_t ecg5_init ( ecg5_t *ctx, ecg5_cfg_t *cfg );

• ecg5_set_mode Mode Setting function.

void ecg5_setMode( ecg5_t *ctx, uint8_t state );

• ecg5_check_lod_negative LOD- Checking function.

err_t ecg5_check_LOD_negative( ecg5_t *ctx );

• ecg5_check_lod_positive LOD+ Checking function.

err_t ecg5_check_lod_positive( ecg5_t *ctx );

Application Init

Initializes ADC and GPIO.

void application_init ( void ) 
{
    log_cfg_t log_cfg;  /**< Logger config object. */
    ecg5_cfg_t ecg5_cfg;  /**< Click config object. */

    /** 
     * 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.
    ecg5_cfg_setup( &ecg5_cfg );
    ECG5_MAP_MIKROBUS( ecg5_cfg, MIKROBUS_1 );
    if ( ADC_ERROR == ecg5_init( &ecg5, &ecg5_cfg ) ) {
        log_error( &logger, " Application Init Error. " );
        log_info( &logger, " Please, run program again... " );

        for ( ; ; );
    }
    log_info( &logger, " Application Task " );
}

Application Task

Reads ADC value and sends results on serial plotter every 5 ms.

void application_task ( void ) 
{
    uint16_t ecg5_an = 0;
    if ( ecg5_read_an_pin_value( &ecg5, &ecg5_an ) == ADC_SUCCESS ) {
        log_printf( &logger, " %u,%lu\r\n ", ecg5_an, time );
    }
    time += 5;
    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.
