ECG 3 Click is a complete solution for ECG and HR application development, utilizing a specialized IC with a clinical-grade analog front-end (AFE). ECG 3 Click uses the MAX30003 IC, an ultra-low power, single-channel bio-sensor, which features a wide range of different options, making it an ideal solution for development of heart rate and ECG monitoring applications, fitness applications, for the ECG bio-authentication, and similar applications related to heart monitoring. ECG 3 Click is also equipped with the 3.5mm electrodes connector, making it ready to be used out of the box.

Click library

  • Author : MikroE Team
  • Date : Jan 2020.
  • Type : SPI type

Software Support

We provide a library for the Ecg3 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 Ecg3 Click driver.

Standard key functions :

  • Config Object Initialization function.

    void ecg3_cfg_setup ( ecg3_cfg_t *cfg );

  • Initialization function.

    ECG3_RETVAL ecg3_init ( ecg3_t ctx, ecg3_cfg_t cfg );

  • Click Default Configuration function.

    void ecg3_default_cfg ( ecg3_t *ctx );

Example key functions :

  • Function reads ECG data from FIFO register.

    void ecg3_get_ecg ( ecg3_t ctx, uint32_t out_ecg );

  • Function checks a status flag for the desired interrupt.

    uint8_t ecg3_check_status ( ecg3_t *ctx, uint32_t bit_mask );

  • Function reads Heart Rate and R - R data and calculates HR data to BPM, and RR data to ms.

    void ecg3_get_rtor ( ecg3_t ctx, uint16_t out_hr, uint16_t *out_rr );

Examples Description

This Click is made for ECG and HR, equipped with an ultra-low power, single channel, integrated biopotential AFE, with the ECG and R-to-R detection functionality.

The demo application is composed of two sections :

Application Init

Initializes SPI interface and performs the all necessary configuration for device to work properly.


void application_init ( void )
{
    log_cfg_t log_cfg;
    ecg3_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.

    ecg3_cfg_setup( &cfg );
    ECG3_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ecg3_init( &ecg3, &cfg );

    ecg3_sw_reset( &ecg3 );
    ecg3_fifo_reset( &ecg3 );
    Delay_ms ( 100 );

    ecg3_default_cfg ( &ecg3 );
    Delay_ms ( 300 );
}

Application Task

Reads ECG Data every 8ms and sends this data to the serial plotter.


void application_task ( void )
{
    ecg3_get_ecg( &ecg3, &ecg_data );

    plot_ecg( );
} 

Note

Additional Functions :

  • void plot_ecg() - Sends ECG Data to the serial plotter.
  • void logrtor() - Sends Heart Rate and R - R Data to the uart terminal.

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.Ecg3

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.
