Hello! I am new to BNO055. I have a BNO055 mounted vertically with: X axes pointing downwards Z axes pointing towards observer horizontally Y axes pointing towards observer's right What should be the Axes Order to obtain Euler angles? The default ZYX works well when the sensor is placed horizontal where Z is the heading, Y is the pitch and X is the roll. But unfortunately when I mount the sensor in vertical position (as required by the application), I am unable to obtain usable values. Pardon my ignorance but in NO_FUSION mode I have tried all 12 combinations and observed that for GYRONLY mode: Calibration status is always s0 g0 a0 m0 All angles never change from zero values despite movement in all coordinate directions If I do not need accelerometer and magnetometer data and want only gyroscope data shouldn't I use NO_FUSION and GYRONLY? Your advice will help me to use the sensor in the correct intended manner. Thanks. Kind regards. ... View more

Hello! I'm a newbie embarking on connecting a BME680 (Schenzen) to a Raspberry Pi board. The BME680 board has the following pins - VCC, GND, SCL, SDA, SDO & CS. Are there any recommendations on the corresponding matching pin on the Raspberry Pi board? I will be using the BoschSensortec C library at GitHub (but don't need any help with that, at least for now). I've used a third party Python library with another variation of a BME680 board and I'm comfortable in reading the data (if I get the hardware connections correct). My current interest would be to leverage C (simply because it can be done!) and not to rely on a 3rd party Python library. I search the community site but could not find any reference. The 3rd party board simply used SDA & SCL pins. I understand the difference between SPI and I2C (just little bit, if I may add but not in current context). My usage several years ago was simply a blind emulation of the instructions. Right now I would like to understand the BME680 a little better with a view to using it as a base level sensor for my projects. I would appreciate it if there is reference recommendation from more experienced/advanced members of this forum to suggest pin connections between the BME680 and a Raspberry Pi (any model will be fine for my limited purposes). Thanks. Kind regards. ... View more
