Hey! So I recently got a new sensor, the BNO08X Sensor, and did I2C connections on this sensor to run a QuaternionYawPitchRoll example provided by Adafruit. However, even after doing the connections on a breadboard listed by Adafruit ( Overview | Adafruit 9-DOF Orientation IMU Fusion Breakout - BNO0…

The default I2C address for the BNO08x is 0x4A which is what the library uses as default. The address can be switched to 0x4B by pulling the DI pin high to VCC ➜ may be your module is using 0x4B? Have you tried running an I2C scan?

Hm interesting No I haven't ran an I2C scan. How do you do an I2C scan?

there are codes online like @robtillaart multispeed I2C Scanner Arduino/sketches/MultiSpeedI2CScanner at master · RobTillaart/Arduino Arduino libraries, code and applications. Contribute to RobTillaart/Arduino development by creating an account on GitHub.

I have a question, so what will the I2C scan return as a result?

Update: I scanned and found that my address is 0x4B. However, my sensor does not have a DI pin. This is because I didn't buy the sensor from Adafruit, and it's a purple-colored sensor I am using. Is there a way to still switch the address? Let me upload a picture to show how the sensor looks: [202…

@J-M-L Ignore my last message, I think I figured it out. I edited the header file of the library. Let me test to see if it retrieves data now.

Great - that was likely your issue. The pin might be just hardwired on your module. Changing the library is one way to do it but if one day you download an update of the library or install a new PC then your code will go back to the default. Double check the library example and .h file, the funct…

Thanks @J-M-L . I might need your help on another issue I just encountered. Now my I2C is displaying data, but I want to try using SPI for faster data. So I made the connections as listed in this link (except with DI being connected as MOSI): Overview | Adafruit 9-DOF Orientation IMU Fusion Breakout …

The same issue occurs with UART as well. If someone can assist me with UART or SPI, that would be great!

does your module have level shifting circuitry to adjust to 5V? for example for UART more, Adafruit uses 3.3V for Vin [image]
