Hi, I am trying to connect 2 Sparkfun sensors (temperature and Lidar) without success (they run fine on an Arduino Nano). No errors besides the "Cannot connect to ". Any ideas? I tried in 2 different S3 boards.

`/** Example1_Basic_Temperature_Readings.ino Example for the TMP102 I2C Temperature Sensor Alex Wende @ SparkFun Electronics April 29th 2016 ~

This sketch configures the TMP102 temperature sensor and prints the temperature and alert state (both from the physical pin, as well as by reading from the configuration register.

Resources: Wire.h (included with Arduino IDE) SparkFunTMP102.h

Development environment specifics: Arduino 1.0+

This code is beerware; if you see me (or any other SparkFun employee) at the local, and you've found our code helpful, please buy us a round!

// Include the SparkFun TMP102 library. // Click here to get the library: http://librarymanager/All#SparkFun_TMP102

include // Used to establied serial communication on the I2C bus

include // Used to send and recieve specific information from our sensor

// Connections // VCC = 3.3V // GND = GND // SDA = A4 // SCL = A5 const int ALERT_PIN = A3;

TMP102 sensor0; // Sensor address can be changed with an external jumper to: // ADD0 - Address // VCC - 0x49 // SDA - 0x4A // SCL - 0x4B

void setup() { Serial.begin(115200); Wire.begin(); //Join I2C Bus

pinMode(ALERT_PIN,INPUT); // Declare alertPin as an input

/* The TMP102 uses the default settings with the address 0x48 using Wire.

 Optionally, if the address jumpers are modified, or using a different I2C bus,
 these parameters can be changed here. E.g. sensor0.begin(0x49,Wire1)

 It will return true on success or false on failure to communicate. */

Serial.println("Connected to TMP102!"); delay(100);
