Resolved! Coordinate transformation from g-sensor frame to world frame?
Dear Sir,Generally speaking, the coordinates of the g-sensor on the PCB board have an angular deviation from the world coordinates. Assume that the coordinates of the g-sensor are (Xs, Ys, Zs) and the world coordinates (X, Y, Z) have alpha, beta and...
Resolved! Aligning the coordinate systems of accelerometer and vehicle?
I have an accelerometer located in an arbitrary position on a car. As the accelerometer already has a coordinate system by default, I want to find some method that allows transforming the data I have from the sensor and aligning them with the coordin...
Resolved! MotionFX with Third-Party Arm Cortex M4F
Hello,My team is developing a product that integrates the LSM6DSM and IIS2MDC, and we would like to use the MotionFX library for sensor fusion. How can we accomplish this, given that we are using a third-party ARM Cortex M4F processor (not STM)?I hav...
g-sensor value on Z direction is negative when Z-axis is downwards?
Dear SIR,I found that LSM6DSR got negative value when X-axis is upwards, got negative value when Y-axis is upwards.Why only Z-direction got postivie value when Z is upwards?That seems break the right-hand-rule direction. Is ther any reason for that?T...
Why doesn't the SensorTile show up when scanning with bluetooth?
Hi, I am developing a STM32L476JG using a STM32 Nucleo for analysis of raw accelerometer data. I wanted to use the ST BLE Sensor app to do some testing, but I am not able to get the device to show up on the list of Bluetooth devices on the app. The b...
Not getting interrupts on INT1 or INT2 pins.#LSM6DSOX.
I am interfacing LSM6DSOX with NRF52, I am trying to get interrupt on INT1 pin but couldn't.I am getting IS_TILT on EMB_FUNC_STATUS_MAINPAGE.I am using the code application note as follows.Can you please guide me on where I am doing wrong
