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;
 }
 }
 }
}

Other mikroE Libraries used in the example:

  • UART
  • Conversions
  • I2C

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.

Angle 9 click

0

Angle 9 Click is a compact add-on board that detects the absolute position of a permanent magnet. This board features the AAS33001, a precision angle sensor with incremental and motor commutation outputs and on-chip linearization from Allegro Microsystems. It is a contactless angle sensor for 0° to 360° angular position, rotation speed, and directional measurement. Support for incremental output interface (ABI) and motor commutation (UVW) is also available. The same goes for the on-chip EEPROM for storing factory and customer calibration parameters.
