Error

[simtcrom]

I am running below,

#include "MAX30100.h" #include <Wire.h>

MAX30100* pulseOxymeter;

void setup() { Wire.begin(); Serial.begin(115200); Serial.println("Pulse oxymeter test!");

//pulseOxymeter = new MAX30100( DEFAULT_OPERATING_MODE, DEFAULT_SAMPLING_RATE, DEFAULT_LED_PULSE_WIDTH, DEFAULT_IR_LED_CURRENT, true, true ); pulseOxymeter = new MAX30100(); pinMode(2, OUTPUT);

}

void loop() { //You have to call update with frequency at least 37Hz. But the closer you call it to 100Hz the better, the filter will work. pulseoxymeter_t result = pulseOxymeter->update();

if( result.pulseDetected == true ) { Serial.println("BEAT");

Serial.print( "BPM: " );
Serial.print( result.heartBPM );
Serial.print( " | " );

Serial.print( "SaO2: " );
Serial.print( result.SaO2 );
Serial.println( "%" );

} }

getting error

any one can help to fix?

Hi could you fix it?

Hello.

Quickly glancing it seems you have 3 pulseoxymeter libraries installed and they inconveniently have the same name. The linker is not able to figure out which one to use.

So either rename the libraries or delete the ones you don't use and it should work.
