ECG GSR click

ECG GSR click is a complete solution for PPG, ECG and GSR application development, utilizing a specialized IC with a clinical-grade analog front-end (AFE) and electrical front-end. ECG GSR click uses the AS7030B IC, an ultra-low power, multi-channel bio-sensor, which features a wide range of different options, making it an ideal solution for development of blood oxygen level, heart rate and galvanic skin response monitoring applications, fitness applications, for the ECG bio-authentication, and similar applications related to heart monitoring. ECG GSR click is also equipped with the 3.5mm electrodes connectors, making it ready to be used out of the box.

Click library

  • Author : MikroE Team
  • Date : Jan 2021.
  • Type : I2C type

Software Support

We provide a library for the ECG GSR 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 compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for ECG GSR Click driver.

Standard key functions :

  • Config Object Initialization function.

    void ecg_gsr_cfg_setup ( ecg_gsr_cfg_t *cfg );

  • Initialization function.

    ecg_gsr_err_t ecg_gsr_init ( ecg_gsr_t *ctx, ecg_gsr_cfg_t *cfg );

  • Click Default Configuration function.

    void ecg_gsr_default_cfg ( ecg_gsr_t *ctx );

Example key functions :

Examples Description

This click is made for PPG, ECG and GSR, equipped with an ultra-low power, multi channel, integrated biopotential AFE and EFE.

The demo application is composed of two sections :

Application Init

Initializes driver, performs SW reset of all the registers, which puts the registers in their initial state.

void application_init ( void )
{
log_cfg_t log_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, "---- Application Init ----" );
// Click initialization.
ecg_gsr_init( &ecg_gsr, &ecg_gsr_cfg );
Delay_1sec();
Delay_1sec();
}

Application Task

Depending on the user selection, application measures: value of oxygen level in human's blood or heartrate or galvanic skin response

{
// ------------------------------------------------------------
// Check the presence of the ECG GSR Click by reading device ID.
// ------------------------------------------------------------
ecg_gsr_read_dev_id(&ecg_gsr, ECG_GSR_ID_REG, &dev_id , 1);
if ( dev_id != ECG_GSR_DEV_ID )
{
}
// ------------------------------------------------------------
// Enable desired functionality of the ECG GSR Click.
// ------------------------------------------------------------
{
{
{
} else
{
}
return ecg_gsr_ok;
}

Note

The full application code, and ready to use projects can be installed directly from compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.ECG_GSR

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.
