ECG 4 Click

ECG 4 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 reads and processes data from ECG 4 Clicks.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Ecg4

Example Key Functions

• ecg4_cfg_setup Config Object Initialization function.

void ecg4_cfg_setup ( ecg4_cfg_t *cfg );

• ecg4_init Initialization function.

err_t ecg4_init ( ecg4_t *ctx, ecg4_cfg_t *cfg );

• ecg4_module_reset Reset module function.

void ecg4_module_reset ( ecg4_t *ctx );

• ecg4_uart_isr Function performs the uart interrupt routine, reads a data from uart rx buffer and makes a response from the BMD101 device.

void ecg4_uart_isr ( ecg4_t *ctx, uint8_t rx_dat );

• ecg4_enable_ldo_ctrl Function powers up or down control of LDO (Low Drop Out).

void ecg4_enable_ldo_ctrl ( ecg4_t *ctx, uint8_t state );

• ecg4_generic_read Generic read function.

int32_t ecg4_generic_read ( ecg4_t *ctx, char *data_buf, uint16_t max_len );

Application Init

Initializes the driver, sets the driver handler and enables the Click board.

void application_init ( void )
{
    log_cfg_t log_cfg;
    ecg4_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.

    ecg4_cfg_setup( &cfg );
    ECG4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    ecg4_init( &ecg4, &cfg );

    ecg4.driver_hdl = make_response;
    Delay_ms ( 500 );

    ecg4_module_reset ( &ecg4 );
    ecg4_enable_ldo_ctrl ( &ecg4, ECG4_ENABLE_LDO_CTRL );

    Delay_ms ( 1000 );
}

Application Task

Reads the received data and parses it on the USB UART if the response buffer is ready.

void application_task ( void )
{
    ecg4_process(  );
    if ( ecg4_responseReady( &ecg4 ) )
    {
        process_response( );
    }
}

Note

Use the Serial Plot application for data plotting.

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.
