I'm new in using arduino IDE and I have a code for Pulse Oximeter Max30100, NodeMCU ESP8266 and OLED screen, but I have Pulse Oximeter Max30102 -it was available is market- instead of Max30100.
When I changed the library, some members doesn't work.
this is the code:
#include <Wire.h>
//#include "MAX30100_PulseOximeter.h" // this was the previous library
#include "MAX30102.h" // this is the library I added instead of the above one
#define BLYNK_PRINT Serial
#include <Blynk.h>
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include "Wire.h"
#include "Adafruit_GFX.h"
#include "OakOLED.h"
#define REPORTING_PERIOD_MS 1000
OakOLED oled;
char auth[] = "Iewd2gc7QynNOsT_3ZMAnWo8sU9uffU9"; // You should get Auth Token in the Blynk App.
char ssid[] = "*****"; // Your WiFi credentials.
char pass[] = "*********";
// Connections : SCL PIN - D1 , SDA PIN - D2 , INT PIN - D0
//PulseOximeter pox; // and this also was the original line for the next line
MAX30102 pox; // this is the line I've added
float BPM, SpO2;
uint32_t tsLastReport = 0;
const unsigned char bitmap [] PROGMEM=

Please help me fixing this I have to fix it cause it's my graduation project
Please help me
