Hello there,
I am using a Xiao with an expansion board to read and display blood oxygen measurements. The sensor is MAXREFDES 117 which I have connected to pin 0, SDA, SCL, 3.3v, and GND.
I also use the Arduini IDE.
Both the display and sensor work when I upload separate examples.
However, When I include the libraries and files below in one .ino file, I get an error and the upload is not successfully complete.
libraries:
#include <Wire.h>
#include “MAX30105.h”
#include “spo2_algorithm.h”
#include <Servo.h>
#include <pitches.h>
#include <Arduino.h>
#include <U8x8lib.h>
The error:

I am wondering if someone could guide me through fixing this issue.
