using i2c hall sensor

[Bfreak]

Hi. I am trying to use a hall sensor module with sim7080g.

The documentation is not very clear on connections for i2c device, according to pinout on website, I have SDA on pin 13 and SDL on pin 21. What is the address to use i2c device on these pins? The following sketch cannot find i2c device succesfully

`#include "Adafruit_MLX90393.h"

Adafruit_MLX90393 sensor = Adafruit_MLX90393();

define MLX90393_CS 13

void setup(void) { Serial.begin(115200);

/ Wait for serial on USB platforms. / while (!Serial) { delay(10); }

Serial.println("Starting Adafruit MLX90393 Demo");

if (! sensor.begin_I2C()) { // hardware I2C mode, can pass in address & alt Wire //if (! sensor.begin_SPI(MLX90393_CS)) { // hardware SPI mode Serial.println("No sensor found ... check your wiring?"); while (1) { delay(10); } } Serial.println("Found a MLX90393 sensor");

sensor.setGain(MLX90393_GAIN_1X); // You can check the gain too Serial.print("Gain set to: "); switch (sensor.getGain()) { case MLX90393_GAIN_1X: Serial.println("1 x"); break; case MLX90393_GAIN_1_33X: Serial.println("1.33 x"); break; case MLX90393_GAIN_1_67X: Serial.println("1.67 x"); break; case MLX90393_GAIN_2X: Serial.println("2 x"); break; case MLX90393_GAIN_2_5X: Serial.println("2.5 x"); break; case MLX90393_GAIN_3X: Serial.println("3 x"); break; case MLX90393_GAIN_4X: Serial.println("4 x"); break; case MLX90393_GAIN_5X: Serial.println("5 x"); break; }

// Set resolution, per axis. Aim for sensitivity of ~0.3 for all axes. sensor.setResolution(MLX90393_X, MLX90393_RES_17); sensor.setResolution(MLX90393_Y, MLX90393_RES_17); sensor.setResolution(MLX90393_Z, MLX90393_RES_16);

// Set oversampling sensor.setOversampling(MLX90393_OSR_3);

// Set digital filtering sensor.setFilter(MLX90393_FILTER_5); }

void loop(void) { float x, y, z;

// get X Y and Z data at once if (sensor.readData(&x, &y, &z)) { Serial.print("X: "); Serial.print(x, 4); Serial.println(" uT"); Serial.print("Y: "); Serial.print(y, 4); Serial.println(" uT"); Serial.print("Z: "); Serial.print(z, 4); Serial.println(" uT"); } else { Serial.println("Unable to read XYZ data from the sensor."); }

delay(500);

/ Or....get a new sensor event, normalized to uTesla / sensors_event_t event; sensor.getEvent(&event); / Display the results (magnetic field is measured in uTesla) / Serial.print("X: "); Serial.print(event.magnetic.x); Serial.print(" \tY: "); Serial.print(event.magnetic.y); Serial.print(" \tZ: "); Serial.print(event.magnetic.z); Serial.println(" uTesla ");

delay(500); }`

fixed with wire.begin
