Software Support

We provide a library for the ECG_3 Click on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Library Description

Library can perform a control of the ECG 3 Click board. Offers a choice to check registers, write to the registers, read ECG and RTOR Data. Also library performs a calculations necessary to get Heart Rate in BPM value, and R - R Data in ms value. For more details check documentation.

Key functions :

• uint8_t ecg3_writeReg( uint8_t regAddr, uint32_t dataIn ) - Function writes data to the register.
• uint8_t ecg3_readReg( uint8_t regAddr, uint32_t *dataOut ) - Function reads data from the register.
• void ecg3_getECG( uint32_t *outECG ) - Function reads ECG data from FIFO register.
• void ecg3_getRTOR( uint16_t *outHR, uint16_t *outRR ) - Function reads Heart Rate and R - R data and calculates Heart Rate data to BPM, and R - R data to ms.

Examples Description

The application is composed of three sections :

• System Initialization - Initializes peripherals and pins.
• Application Initialization - Initializes SPI interface and performs the all necessary configuration for device to work properly.
• Application Task - (code snippet) - Reads ECG Data every 8ms and sends this data to the serial plotter.

void applicationTask()
{
    ecg3_getECG( &ecgData );
    
    plotECG();
}

Additional Functions :

• void plotECG() - 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 found on our LibStock page.

Other mikroE Libraries used in the example:

• Conversions
• SPI
• UART

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.
