Heart Rate click carries a MAX30100 integrated pulse oximetry and heart-rate sensor. It’s an optical sensor that derives its readings from emitting two wavelengths of light from two LEDs, then measuring the absorbance of pulsing blood through a photodetector. Uses 3.3V power supply.

Library Description Key functions:
- uint8_t heartrate_readIrRed(uint16_t *ir_buff, uint16_t *red_buff ); - This function reads IR and RED values.
- void heartrate_init(); - This function restarts and initializes the Heartrate chip.
- uint8_t heartrateDataReady() - This function checks if the data is ready for reading.
Examples Description
- System Initialization - Initializes GPIO INT as the input pin, I2C, and UART for logging.
- Application Initialization - Initializes heartrate driver and Click board™.
- Application Task - reading the value from both Ir and Red diode displaying their average values.
void applicationTask()
{
if (heartrateDataReady())
{
sample_num = heartrate_readIrRed( &ir_buff, &red_buff );
if ( sample_num >= 1 )
{
ir_average = 0;
red_average = 0;
for ( counter1 = 0; counter1 < sample_num; counter1++ )
{
ir_average += ir_buff[counter1];
red_average += red_buff[counter1];
}
ir_average /= sample_num;
red_average /= sample_num;
counter2++;
if(counter2 > 100)
{
mikrobus_logWrite("Average value of Red LED sensor per 100 samples:",
_LOG_TEXT);
WordToStr(red_average, text);
mikrobus_logWrite(text,_LOG_LINE);
mikrobus_logWrite("Average value of IR LED sensor per 100 samples:",
_LOG_TEXT);
WordToStr(ir_average, text);
mikrobus_logWrite(text,_LOG_LINE);
counter2 = 0;
}
}
}
}

Additional notes and information 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.
