Adafruit_MLX90614 and MAX30102 Not working

[stevemarple]

At this stage the only advice I can give is to submit more detailed error reports. Wiring details, pins used etc are all useful and sometimes necessary information. The Adafruit_MLX90614 library uses the Wire (hardware I2C) library. I have a library (https://github.com/stevemarple/MLX90614) that supports the MLX90614 and it uses SoftWire.

Thank you for your response. Please find my code below.
I am getting the reading for MAX30102 only but not for MLX90614. both are working on I2C. I did change pin for MAX30102 but still, code is not working.

#include <Wire.h>
#include "MAX30105.h"
#include <Adafruit_MLX90614.h>
MAX30105 particleSensor; // initialize MAX30102 with I2C

TwoWire I2CBME = TwoWire(0);
#define IR1 0x5A
#define I2C_SDA 33 //21
#define I2C_SCL 32 //22
Adafruit_MLX90614 mlx = Adafruit_MLX90614(IR1);
void setup()
{
Serial.begin(115200);
while(!Serial); //We must wait for Teensy to come online
mlx.begin();
I2CBME.begin(I2C_SDA, I2C_SCL, I2C_SPEED_FAST);

delay(100);
Serial.println("");
Serial.println("MAX30102");
Serial.println("");
delay(100);
// Initialize sensor
// if (particleSensor.begin(Wire, I2C_SPEED_FAST) == false) //Use default I2C port, 400kHz speed
if (!particleSensor.begin(I2CBME, I2C_SPEED_FAST ,0x57))
{
Serial.println("MAX30102 was not found. Please check wiring/power. ");
while (1);
}

byte ledBrightness = 70; //Options: 0=Off to 255=50mA
byte sampleAverage = 1; //Options: 1, 2, 4, 8, 16, 32
byte ledMode = 2; //Options: 1 = Red only, 2 = Red + IR, 3 = Red + IR + Green
int sampleRate = 400; //Options: 50, 100, 200, 400, 800, 1000, 1600, 3200

particleSensor.setup(ledBrightness, sampleAverage, ledMode, sampleRate, pulseWidth, adcRange); //Configure sensor with these settings
}

void loop() {
particleSensor.check(); //Check the sensor
while (particleSensor.available()) {
// read stored IR
Serial.print(particleSensor.getFIFOIR());
Serial.print(",");
// read stored red
Serial.println(particleSensor.getFIFORed());

The code you posted uses the Wire library. Does MAX30105.h include or somehow use SoftWire?

[fervidautomation]

I am stuck into this problem to use these 2 sensor on esp32, does softwire, can help me?

[stevemarple]

So you aren't using SoftWire? Please report any software bugs you find to the appropriate place. Do not use abuse issue trackers as a personal helpline. The majority of authors of open-source software contribute their time for free.
