ECG 5 Click

ECG 5 Click can be used for the development of ECG and Heart-Rate (HR) applications. The Click boardâ„¢ features the AD8232, an integrated bio-signal front end. This IC has many features necessary for providing accurate ECG measurements, including very high common-mode rejection ratio, high gain with DC blocking capability, adjustable high-pass and low-pass filters, integrated right leg drive (RLD), etc.

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 :

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.

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;
ecg5_cfg_t ecg5_cfg;
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.
