Click library

  • Author : Stefan Ilic
  • Date : Aug 2021.
  • Type : ADC type

Software Support

We provide a library for the ECG5 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 from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for ECG5 Click driver.

Standard 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 );

Example key functions :

  • 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 );

Example Description

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

The demo application is composed of two sections :

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 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

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

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. UART terminal is available in all MikroElektronika compilers.

Accel 24 Click

0

Accel 24 Click is a compact add-on board that contains an acceleration sensor. This board features the MXC6655XA, a 12-bit three-axis accelerometer from MEMSIC. It allows selectable full-scale acceleration measurements in ranges of ±2g, ±4g, or ±8g in three axes with a compatible I2C serial interface with 400KHz fast mode operation. Alongside low offset and temperature signal with high accuracy, the MXC6655XA also detects six orientation positions, X/Y shake, and shake directions with an appropriate interrupt signal for these states.

DIGI POT 13 Click is a compact add-on board that contains a digitally controlled potentiometer. This board features the MAX5419, a 256-tap non-volatile digital potentiometer from Analog Devices. On this Click board™, one digitally I2C-controlled potentiometer is realized with typical end-to-end resistance values of 200kΩ. It can operate from both 3.3V and 5V power supplies and provides a low 35ppm/ºC end-to-end nominal resistance temperature coefficient and only 5ppm/ºC ratiometric.
