Simple Arduino library for the Bosch BMI270 inertial measurement unit over the SPI bus

bmi270-spi's Issues

Getting error -9 on example sketch: bmi270_init failed with code -9: CONFIG_LOAD

Hello,

Thanks for developing this library, I have been looking for hours for something I could use with my sensor and it seems that this will be perfect for it. I am trying to use the library to connect the MikroE 6DOF IMU 12 Click board to an Arduino Nano Every. I have made the proper connections between the boards and I am running the included Standard example sketch. After flashing, I get the following error in the serial monitor:

bmi270_init failed with code -9: CONFIG_LOAD

Is there some additional configuration file that I should be using? How should I go about fixing this error?

The exact code I'm trying to run is as follows:

        printval(imu.getRawGyroX(), "gx");

        Serial.println();
    }

    delay(10);
