I2C issue with BNO055 from Adafruit #81
Description
Tried to connect the ESP32 with the sensor BNO055 from adafruit (https://learn.adafruit.com/adafruit-bno055-absolute-orientation-sensor/wiring-and-test).
Used the latest commit of arduino-esp32, downloaded the libraries from adafruit, and used their code as well:
#include <Wire.h> #include <Adafruit_Sensor.h> #include <Adafruit_BNO055.h> #include <utility/imumaths.h> Adafruit_BNO055 bno = Adafruit_BNO055(55); void setup(void) { Serial.begin(9600); Serial.println("Orientation Sensor Test"); Serial.println(""); /* Initialise the sensor */ if(!bno.begin()) { /* There was a problem detecting the BNO055 ... check your connections */ Serial.print("Ooops, no BNO055 detected ... Check your wiring or I2C ADDR!"); while(1); } delay(1000); bno.setExtCrystalUse(true); } void loop(void) { /* Get a new sensor event */ sensors_event_t event; bno.getEvent(&event); /* Display the floating point data */ Serial.print("X: "); Serial.print(event.orientation.x, 4); Serial.print("\tY: "); Serial.print(event.orientation.y, 4); Serial.print("\tZ: "); Serial.print(event.orientation.z, 4); Serial.println(""); delay(100); } I get the following error message on serial: "Ooops, no BNO055 detected ... Check your wiring or I2C ADDR!" and if I check the SCL / SDA with the scope I get the following result:
Mention: I double checked the wiring!
I don't know what the issue might be, any help would be great.
